Indicators of short-circuit are designed for localisation of the damaged area on overhead lines of power distribution networks with voltage 6-35 kV, network frequency 50 Hz and 60 Hz, with any type of neutral (blind-earthed, resistive, compensated isolated) with one-sided power supply, ring lines with two-sided power supply. The set consists of three indicators: IKZ-V53L-Master (1 pc.) and IKZ-V53L-S (Slave 2 pcs.), controls and continuously monitors the current and voltage in each phase wire of the overhead line, provides joint data processing, and data transfer to the data acquisition server.
The IKZ-V53L-U3 detects short circuits from 20 A, short-circuit faults from 2 A. IKZ-V53L do not require a separate unit for data transmission via GSM-network, SMS notification of accidents with GPS coordinates can be organised.
All indicators of the set are equipped with radio channels of BLE standard, IKZ-B53L-Master is equipped with GSM-channel of data transmission. IP 68
