ASM-Portable – Portable PD Monitor

The ASM-Portable is a Portable Partial Discharge (PD) Monitor for cables, switchgear, and other high-voltage assets. The unit is part of the IPEC’s wider range of on-line PD monitoring systems. The ASM-P can be configured with up to 32 PD sensor channels. If excessive discharge is detected, the ASM-P raises an alarm that can be configured either locally or by email. This enables the long-term assessment of plant conditions to be carried out quickly and easily, from any remote computer.

Sensors are distributed around the substation according to the monitoring requirements. Both active (with integral amplifiers) and passive transducers are compatible including the following:

• High Frequency CTs – for cable PD detections
• Capacitively Coupled – for TEV (Switchgear) PD detection
• Airborne Acoustic – for Surface tracking or corona
• Temperature and Humidity – environment measurements
• Up to 32 sensors can be monitored by a single ASM-P.
