GIS partial discharge counter

Device that detects the presence of partial discharge of GIS

Device that detects the presence of partial discharge of GIS. It consists of PD Counter, external UHF Sensor, Noise Sensor, and BRF (Band Rejection Filter). A built in algorithm to recognize and determine partial discharge pattern and type is also present. By applying a noise sensor and a BRF to remove noise signal according to the operation level and the reference density setting, accurate partial discharge can be determined. Up to three PD sensors can be connected, making it possible to see the effect of 3 units in one, greatly reducing the cost and allowing easy remote monitoring using communication function (contact point, RS485, LAN)

ZCP System

As a railway protection monitoring system, opening and closing are possible by a 3-phase interlocking system, by differentiating it from a disconnector that operates only when there is no load. It is installed and used in domestic high-speed railways.
