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. This enables the long-term assessment of plant conditions to be carried out quickly and easily, from any remote computer. Suitable for all types of substation equipment, the ASM proves a powerful tool to an asset manager, providing continuous on-line condition data at the touch of a button.
