The Sonus PD Alert is an asset-mounted device for indicating the presence of partial discharge in high voltage switchgear, ring main units (RMUs) and transformers. Designed for use in small substations, the instrument can activate local and remote alarms in addition to local indication. The Sonus PD Alert is built into a tough case that magnetically mounts to the RMU. Installation is very quick and simple with only a power connection required to get the system operational. Alarms can be configured to operate either locally with SCADA or remotely using an optional integrated modem. The system incorporates algorithms that distinguish noise from real PD, significantly reducing the likelihood of getting false alarms. The status and PD levels are displayed on a bright OLED display at the front of the unit.
Early warning about defects that can lead to failure
Designed for large scale roll out across distributed assets, the monitoring system allows for a decrease in man-hours usually associated with inspection rounds.
Implement as part of a Condition Based Maintenance program to monitor assets and receive notifications to inspect for possible faults before failure strikes.
