OPERATIONAL NEGOTIATIONS – exchange of information in the process of personal communication between duty, operational and production and production personnel using communication means about the condition of equipment at power facilities, organization of repair work by both the personnel of the oblenergo and other enterprises (licensees, railway, Centrenergo, etc. .), as well as with non-electrical personnel of third-party organizations (Ministry of Emergency Situations, SBU, etc.) on issues related to the production activities of the enterprise ( natural disasters, theft, etc.).
4.2. All operational negotiations must be conducted in Ukrainian or Russian. Before commencing operational switching, duty personnel are required to consider the content and sequence of upcoming negotiations. Operational negotiations must be conducted technically competently, using the technical terms recommended in GKD 34.35.507-96, GKD 34.20.563-96, GKD 34.20.507-2003 and in accordance with the “Instructions for making inscriptions and designations on electrical equipment of electrical networks” . In orders for operational switching, all electrical equipment of substation, overhead lines, RP, TP, CL, relay protection and control devices, SDTU devices must be named in full in accordance with the uniform operational dispatch names, briefly and clearly. Reductions are allowed in accordance with ODS-2.
4.3. At the beginning of the conversation, persons participating in the upcoming negotiations are required to provide the name of their object, position, and introduce themselves by last name. When conducting operational negotiations via dispatch channels, it is allowed to limit oneself to reporting the last name. The following order of negotiations is adopted, namely: the person who received the call is introduced first, and the person calling second. In the future, addresses by name and patronymic are allowed. Friendly relationships are prohibited, i.e. calls by name. When making entries in the operational journal, it is allowed to limit oneself to indicating only the surname, provided that there is no person with a similar surname at this unit.
4.3. When conducting operational negotiations, it is PROHIBITED:
- use cellular communications if it is impossible to record on a magnetic medium;
- conduct conversations of an extraneous, personal nature;
- use “adverbs and particles” (“so”, “too”, “also”, “well”, “yes”, etc.).
4.4. In general, the form of an operational conversation should be structured according to the following scheme:
- Object name;
- position and surname of duty personnel, operational and production personnel, maintenance personnel;
- content of an order, message, request, report, information.
4.5. If the personnel involved in operational switching violates the requirements of this instruction regarding the procedure for conducting negotiations, any of the negotiation participants is obliged to make a remark. A person who has received a remark about a violation of the procedure for conducting operational negotiations, switching, has not responded with an appropriate action, or has entered into an argument-dialogue, is subject to removal from operational negotiations, switching.

GENERAL PROVISIONS
The instructions are compiled in accordance with the "Rules for the operation of consumer electrical installations /PEEP ed. 5th/, instructions for switching in electrical installations /TI-34-70-040-85/, Safety Rules for the operation of consumer electrical installations /4th edition 1994/ , directive materials and is an addition to the current instructions on the production of operational switching, on the prevention and elimination of accidents and abnormal conditions, on the registration of applications for equipment removal for repair.
Knowledge of these instructions is mandatory for operational and operational-repair personnel of the NGKhK energy service, engineering and technical personnel of the industrial sector, and management of the OGE.
OPERATIONAL TERMINOLOGY IN NEGOTIATIONS AND ABBREVIATIONS IN OPERATIONAL RECORDS.
In order to organize records in operational documentation, for all operational personnel of the enterprise it is accepted one system abbreviations and terminology.
Operational terminology of operations.
The operation of closing an electrical circuit with any switching device /switch, disconnector, machine, separator, etc./ is called TURN ON.
The operation of opening an electrical circuit by any switching device is called DISCONNECTING.
The terms "DISCONNECTION" and "CLOSING" also apply to the connection generally located within the substation (for example, a transformer, etc.). In this case, these words mean turning on or off all switches and disconnectors of the connection. In this case, a certain sequence of switching on or off switching devices is observed, which is established by order / command / of a superior duty officer or a switching form. Examples of commands and entries:
Enable / disable / TR-110-1T PS “Stroitelnaya”.
"According to B.P. N04 at the Stroitelnaya substation, put 2T into operation.
"According to B.P. N05 at the Stroitelnaya substation, take out for repair 1 section of 110 kV busbars and TN-110-1.
At the Stroitelnaya substation, assemble a 1T circuit on the 110 kV side.
At the Stroitelnaya substation, assemble a 1T circuit on the 10 kV side.
Disconnecting live parts from the ground is called BY REMOVAL OF GROUNDING. This operation means removing the portable grounding or disconnecting the stationary grounding disconnector from all three phases, unless there is special instructions.
The connection of two or three phases to each other without connection to the ground is called BY SHORTING. Indicating exactly which phases. Reverse operation - REMOVAL OF SHORT SHORT.
For relay protection and automation devices, during operations to put them into operation and take them out of operation, uniform terms are established: " Enter device" And " Withdraw device". Example:
"Bring DZT - 2T to the Stroitelnaya substation»
A change in the reading of any instrument in one direction or the other is called, respectively, " INCREASE" or " DOWNLOAD" indicating the changed value, to what value. Example:
Voltage for 1 sec. from 10 kV dropped to 5.8 kV.
The action of relay protection and automation devices, which is established according to the readings of the corresponding devices / blinkers, illuminated displays, etc. / regardless of the consequences caused / turning off or turning on switches, etc. / is called TRIGGEMENT, indicating the protection or automation device. The activation of protection and automation by operational personnel is recorded in the operational documentation, necessarily listing the panel numbers, dropped blinkers and illuminated light displays. Triggering of an automatic reclosure or automatic reclosure is regarded as SUCCESSFUL, UNSUCCESSFUL or REFUSAL.
The successful operation of an automatic reclosure or automatic transfer system is considered to be one in which the circuit breaker remains in the on position after the action of the automatic reclosing or automatic transfer system on it. Unsuccessful operation of the automatic reclosure or automatic transfer system, in which the circuit breaker, which was turned on by the influence of the automatic reclosing or automatic transfer circuit on it, was again disconnected from the protection.
If, in the event of an emergency and the presence of factors inherent in the operating principle of the automatic reclosure or automatic transfer system, the circuit breaker is not turned on and the operation blinker does not fall out, then in this case it is considered that the automatic reclosure or automatic transfer system has failed.
About any disconnection of the circuit breaker that occurred due to the action of relay protection and automation devices, one should say EMERGENCY DISCONNECTED with the addition of the triggered devices after that. When turning off/on/ the switch with a key, remotely or by personnel acting on the drive, you should say OFF /ON/ manually. When it is turned off/on/without the influence of personnel or protection devices/automation/, it is said to turn OFF/ON/ spontaneously.
The loss of voltage from any piece of equipment is called BY REDEMPTION with a precise indication of exactly which elements have been extinguished: For example: “1 s.sh. 110 kV has been extinguished.” The extinguishing of all buses / of the entire substation / is called IN FULL REPAYMENT, and parts of the accessions PARTIAL REPAYMENT, and the extinguished connections are listed.
Accepted abbreviations in operational records. The text of this chapter provides examples of short names. These abbreviations are used for entries in operational documentation. When reading and conducting operational negotiations, these abbreviations should be considered the full text.

GENERAL PROVISIONS ABOUT NEGOTIATIONS AND RECORDS.
Operational negotiations are an integral part of the most responsible work of the duty personnel in making switching operations and eliminating accidents. Therefore, operational negotiations must be extremely clear and specific. The operational language must exclude the possibility of personnel misunderstanding the nature and content of the dispatcher's orders or the dispatcher misunderstanding messages from facilities.
Having received an order / message about the execution of an order or operational information from a power facility /, the personnel on duty must repeat it so that the first person is convinced that it was understood correctly.
Any operational negotiations of duty personnel should begin with the mutual communication of their position and last name, and when using backup or technological communication channels, in addition to direct operational ones, the object of the speaker should also be reported, examples:
DEM Ivanov,
DEM of the Ivanov OZH site.
DODS SES Kudinov,
14.00 DEM PS “Stroitelnaya” Ivanov.
If the person receiving the order does not understand, then he is obliged to ask again and clarify it with the person giving the order. An order that threatens the lives of people or the safety of equipment WILL NOT BE FOLLOWED. The duty officer informs the person who gave this order /with a brief motivation/ about his refusal to carry out the order, and formalizes this refusal with a corresponding entry in the operational log.
During operational negotiations, the use of abbreviated names, equipment designations and operational actions IT IS STRICTLY PROHIBITED, because When talking on the telephone or radio station, abbreviated names may be distorted and misunderstood. It is permitted, as an exception, during operational negotiations to use abbreviated designations for relay protection and automation devices indicated in Table 2.1..
Requests for meter readings must be specific, for example:
“What is the active load on the 10 kV overhead line L-104 of the Stroitelnaya substation.
“Please report the readings of the ammeters on the 10 kV side of the 1T transformer” at the Stroitelnaya substation.
On-duty personnel of any rank are required to answer all telephone calls, as well as radio calls, temporarily interrupting conversations with other subscribers, and when called by a higher-ranking duty officer/dispatcher/interrupting negotiations with any subscriber, incl. and with leaders of any rank.
PROCEDURE FOR RECORDS ON SHIFT ACCEPTANCE AND DELIVERY AND REPORTS ON ENTRY ON DUTY.

- Used switching forms (including damaged forms) must be stored for at least 1 month. During this time, they must be transferred from all structural divisions and checked at the UDS ES, for TPPs - at the PDS oblenergo. Based on the results of the inspections, measures should be developed within a month to prevent similar errors in the future. Copies of BPs that have errors should be sent weekly to the oblenergo PDS for their analysis and systematization (by fax, courier, e-mail).
- The instructions developed by the production and dispatch service of oblenergos have the symbol DO-No., where No. is the number of the corresponding instruction. The number is followed by the name of the instruction. In every Electrical Networks on the basis of each instruction DO-No., the corresponding local instruction ODS-No. (with the same number) must be developed, taking into account the necessary changes and additions related to the characteristics of the electrical networks in use.
- Instructions “DO”, “ODS” must be constantly located at the workplace of operational personnel, for whom their action is mandatory. They must be printed on paper and a printing device of appropriate quality, ensuring them a long service life, preventing operational personnel from independently replacing sheets, and having a neat appearance. In case of damage or loss of the instructions, a copy of proper quality must be immediately made.
KEEPING AN OPERATIONAL JOURNAL
- Maintaining your own operational log is mandatory for each energy facility, substation 35 kV and above, each substation of the regional power distribution system, substation of the power plant, gas substation of oblenergo, OVB, thermal power plant shop. By decision of the management of power plants, their structural divisions, thermal power plants, the specified list of objects with mandatory maintenance of an operational log can be expanded.
- The operational log is maintained in accordance with the requirements of Section 6 and the additional requirements below.
- The operational log should be reviewed daily:
- in the ES - the head of the UDS or his deputy;
- at the substation – the head of the substation group or his deputy (for remote substations - upon arrival at the substation);
- in RES - chief engineer of RES or deputy. Head of the Distribution Zone for Operations;
- at thermal power plants - shop manager, chief engineer or his deputy,
confirming this by fixing the date and your own signature in the margins of the journal, record your comments in the margins and take the necessary measures to eliminate the identified comments.
- Under normal (non-emergency) conditions, entries in the operational journal are made before the operation is performed, immediately after receiving or issuing an order.
- When eliminating an accident, to speed up switching, it is allowed to make preliminary entries in workbook dispatcher, duty officer or on a separate sheet, and then, if there is free time, immediately transfer them to the operational journal with full description everything done during the liquidation of the accident.
- Entries in the operational journal are kept in chronological order. In the event of a violation of the chronology, a note is made in the margins of the journal: “Missed entry” and the signature of the operational person on shift is affixed.
- Each entry must begin with recording the time of receipt or issuance of an order (permission), or receipt of a message. The text of the record may indicate the times of individual operations, actions of operational personnel, and events. Examples of records for oblenergo DD are given in Appendix No. 2.
- Operational personnel must record in the operational log:
- operational orders received, issued, executed;
- changes in the operational state of equipment, power lines, relay protection and automation devices, SDTUs under its operational control, indicating the position of switching devices and grounding mode;
- results of inspections of equipment at substations, thermal power plants, power lines carried out during the shift;

- orders to limit and disconnect consumers or introduce regulatory measures, indicating the magnitude and reason;
- orders through the Ministry of Emergency Situations;
- start and end times of tests according to approved or agreed upon programs;
- other incidents, violations, events, phenomena that, in the opinion of operational personnel or their management, can have or are having a significant impact on the operational situation.
The specified volume of records is a minimum. Depending on the specific conditions and the importance of the messages, the duty personnel makes records that they deem necessary.
- At power plants, substations, power facilities and control centers of distribution zones, in the operational logs of the fire safety equipment, the installation and removal of all types of grounding must be recorded in the operational log using special stamps. Stamp installations grounding is placed in the left half of the magazine page, and the stamp removing this grounding – directly next to it, on the remaining free right half of the page (see Fig. 6.1). When installing and removing portable grounding, the grounding number is entered in the corresponding field of the stamp. When switching on (off) stationary grounding blades, “SZN” is indicated in the grounding number field.
Figure 6.1 Stamps for installing and removing grounding used in oblenergo
- On the DP ES it is allowed to apply special symbols and stamps in the text and in the fields of the operational journal, opposite the entry about the installation (removal) of groundings, etc. Appearance the indicated symbols and stamps, as well as the procedure for their use, must be specified in the local instructions for maintaining an operational journal.
- At the substation and DP RES, when handing over a shift, the handover recorder lists the number of installed groundings, indicating the numbers and the number of the next blank switching form. If any portable grounding connections are missing (under repair), then this should be mentioned in the grounding records when handing over the shift.
- Leaving duty without registering the change of shift in the operational log is prohibited.
MAINTAINING THE OPERATIONAL SCHEME.
- Each substation of 35 kV and above, each substation of regional power grids, power plants, oblenergos, main control rooms of thermal power plants must be equipped with a mnemonic diagram. In the absence of a mnemonic diagram, each of the above objects must be provided with an operational diagram.
- A mnemonic diagram is a single-line diagram of the primary connections of the corresponding enterprise, division, or electrical installation. It must be equipped with special posters with symbols printed on them that determine the position of switching devices (if models of switching devices with a variable state are not provided), the operational state of the equipment, the location of grounding installations and other necessary posters, based on specific operating conditions.
- The operational diagram is a copy of the approved single-line diagram of the normal operation of the corresponding enterprise, division, or electrical installation.
- The name of the equipment and switching devices displayed on the mnemonic diagram (operational diagram) must correspond to the dispatch names printed on the normal mode diagram.
- The operating personnel maintains a layout diagram (operational diagram), displaying on it all the changes that occur during the shift, immediately after operational switching, and hanging posters with the necessary symbols on the switching devices being adjusted, in all places where grounding is installed, both portable and and stationary. The marks on the operational diagram are made carefully with dark paste using special symbols and symbols. Recording in pencil or permanent ink is strictly prohibited.
- After the commissioning of new equipment or a new power line, reconstruction of the network, appropriate changes must be immediately made to the mnemonic diagram (operational diagram).
- The senior operational person on the shift is responsible for maintaining the layout diagram (operational diagram).
- At the oblenergo gas control center, posters and symbols given in Appendix 3 are used to maintain a mnemonic diagram.
