Partial Discharge Management System

ISAAC-PDS-PDMS

Product Overview
Insulation defects caused by prolonged operation of power facilities including switchboards, power cables, and GIS are some of the main causes of power plant failure. Insulation defects result in partial discharge, which causes the insulation to deteriorate, leading to power outage.

ISAAC-PDS-PDMS functions for inputting and transmitting HFCT sensors by attaching them to a ground wire to detect isolation of ultra high-pressure cables to higher operating systems and data management.

It receives window type and drain valve insertion type UHF sensor signal for partial discharge diagnosis of transformer and transmitting it to upper operating system and data management.

Capable of receiving window type UHF sensor and noise sensor signals for diagnosis of partial discharge of GIS, transmitting them to higher operating system, and data management.

Also on HFCT, TEV, AE, TEV / AE complex, noise sensor signals for diagnosis of partial discharge of cable connection and internal part of ultra high voltage switchboard and transmitting them to the upper operating system and data management.
