CABLE CONTROL SYSTEM

Cable control system is an innovative system for power cables integrated monitoring based on PLUTON current developments. Cable control system is provided for internal and external cable insulation resistance values measurement in traction networks up to 1000V DC. The aim of system implementation is to prevent emergency situations in case of power cable insulation properties degradation. Cable control system was designed as a component of traction network monitoring and protection system SMTN-3, but due to discrete signals for control and signaling cable control system can be operated...

Input signals Internal insulation Screen— External insulation Earthing (return wire) ▲ Diagram of cable connection to cable control system module Monitoring principle is based on cable screen voltage measuring relative to earthing, and comparing of this potential to a reference one. Reference voltage is set with resistances built in the module. Cable internal and external insulation resistance is the branch of resistive bridge. The second branch consists of built-in resistors with known ratings. Recalculation of voltage values on the bridge branches in resistances is made according to...

Main technical data of cable control system CABLE CONTROL SYSTEM Discrete outputs NC/NO relay contacts act as output signals. Contacts parameters are given in the table. The module provides three pairs of contacts for the following alarms: • voltage presence (under network voltage from +430 to +1000 V); • external insulation damage; • internal insulation damage; • cable insulation calculated resistance decrease below the setting. Interface output Interface output is provided for serial, asynchronous data transmission via fiber optic cable to SMTN-3 central processing module. Fiber optic...
