17. Requirements to the radio-frequency cable for joining hf apparatus to the hf highway

• Construction of radio-frequency cable must provide the requirement of his technical descriptions.

• A cable must be intended for exploitation in climatic terms in accordance with the variant of implementation of U1 for GOST 15150-69 and to maintain without the change of descriptions influence of sun radiation during all period of exploitation.

• On-the-spot radio-frequency cable, marking in accordance with the requirements of operating document must be inflicted. Marking must be steady to external climatic influences. All inscriptions must be clear and well visible.

• Gasket cable from HF vehicles (receiver, transmitter) to the filters of joining must be carried out one assembling long (without connectors).

18. Requirement to the devices of determining damage location (ddl) by a wave method

• Simultaneous work with lines/feeders of different class of tension of SS (110 kV and 330 kV).

• Possibility of treatment to 8 connected lines/feeders (24 phases).

• Frequency of discretization / selections on every connected channel must be influenced in a range 1.25 – 20 Mhz. Possibility of selection must be well-to-do with frequency of 20MGc for every connected phase without worsening of index at the increase amount of the connected lines to 8.

• Exactness of location damage not worse +/-100m regardless of length line and type of damage.

• Synchronization of time with GPS by means of built-in receiver not worse what 100nsec.

• Two discrete entrances for every three-phase line for control of basic / reserve defense with the purpose of signaling/filtration of disconnecting a line.

• Connecting must be carried out on the second current chains of TT RP through sectional linear touch-controls.

• Built-in liquid display, management keys and light-emitting diodes of indication of basic indexes.

• Two built-in ports of Ethernet, Rs-485, USB ports of connection.

19. Complete set for the transmission of command rp and sa on fcl

Functional possibilities

• Architecture of the system is module, opened with possibility of configuration on the base of the programmable software.

• Grant physical interfaces of user (including the dedicaded lines of communication) with completion in the signals of high capacity (SDH) and integration in the highway of Stm-1 of a transport network on a base SDH.

• Presence of building in the system interfaces of communication as fibre-optical and on the base of copper cable, allowing to connect the element of network directly to a transport highway or create a transport network (with the limited carrying capacity).

• Presence of functional block`s and test diagnostics.

• Realization of front-end interfaces of access as plug-in assemblies.

• Presence a multiplex access and cross-commutation signals of 64 kbit/s and signals 2 Mbit/s.

• Presence of inbuilt channel for possibility of remote access to the network element by means of communication of management data through a network.

• Presence of the defense modules and discrete signals for possibility of transmission commands of defense from devices RP and SA and transmissions of any discrete signals.

Module of remote defence must provide:

• Presence of separate entrance and output charts for the independent commands of remote defense in one module (block);

• Module of remote defense in part of interface to conform the requirements of IEC 60834-1;

• Speed and reliability of transmission command must be in a position of optimization of transmission on speed or on reliability;

• The channel of transmission command must be controlled contour tests, refuses must be reported and be in a position of conclusion on the external signaling.

• All events of the module remote defense must be registered in the recorder of events with synchronization at times from the signals of GPS.
