Device PSC-7 is designed for integrated monitoring of metal oxide surge arrester without gaps (MOSA) under operating voltage. Monitoring is carried out remotely using data collection console. The device is installed in earth circuit of surge arrester.

Distinctive Features

>> Registration of pulses with selection;

>> Measurement of an amplitude of 1, 3 and 5 leakage current harmonics;

>> Measurement of temperature;

>> The collection of data on the status of the surge arrester is fully automated: readings are transmitted once a day to the data acquisition console via radio;

>> High stability – registers pulses up to 100 kA, amount of maximum amplitude pulses – not limited;

>> High level of dust and moisture protection;

>> Failure of device does not affect operation of surge arrester.
