ASM - Online Partial Discharge Permanent Monitoring

Click on Image to Enlarge

The ASM is a permanent PD monitor for cables, switchgear and other high voltage assets. The ASM can be configured with up to 128 PD sensor channels. If excessive discharge is detected, the ASM raises an alarm that can be configured either locally or by email/SMS. This enables the long-term assessment of plant conditions to be carried out quickly and easily, from any remote computer.
Fibre linked monitoring points transmit PD data over long distances to the main monitoring unit, which then processes the data and displays the results on a secure customer web front end.
