Insulation problems in the additional parts of the low voltage cables cause wear and rapid life loss in these parts. PDS™ is a useful device for partial discharge detection in low voltage cables in industrial facilities. Based on the results of the PDS™ measurement, preventive maintenance work is organized so that malfunctions that cause high costs occur and energy cuts are prevented. PDS™ provides its users by converting the level of partial discharge intensity detected in low voltage cables from electrical charge (pC) unit to decibel (dB) unit.
