03. Sound PD - Handheld Switchgear Partial Discharge Detector

The Sonus PD

Handheld Switchgear Partial Discharge Detector

IRISS

The SONUS PD is specifically designed for Partial Discharge (PD) and Airborne Emission (AE) detection on Medium and High Voltage Switchgear. The unit detects Transient Earth Voltage (TEV) signals generated by internal partial discharge as well as ultrasound acoustic discharge generated by surface tracking, arcing or corona. PD detection can be utilized to detect early warning signs of equipment insulation failure. Inspections can be performed quickly and safely by maintenance personnel with minimal training. Fast and accurate diagnosis of problems using the SONUS PD will help you prevent unexpected outages.

IRISS

TEV and Ultrasound Detection in One Unit

With the ability of the unit to detect either TEV (Transient Earth Voltage) or AE (Airborne Emission), the Sonus PD is ideal for use in facilities with higher voltages. The TEV feature is an effective tool for detection of defects and micro voids in insulation that yield partial discharge while the AE feature allows for the detection of Corona, Treeing (Tracking), Arcing and Loose Connections in electrical gear.

Easy to Use With a Minimal Learning Curve

The Sonus XT units require a minimal amount of training to get an inspection program up and running on your critical assets. Easily transition from an Electrical Inspection to a Motor Bearing Inspection by swapping the airborne probe for the contact probe without any complicated menu setting adjustments.

IRISS

Built-In Bluetooth Functionality

The SONUS PD is unique in PD detection by using a built-in Bluetooth module which allows the SONUS PD to connect with an Android smartphone running the SONUS PD App. The user may then take and store readings in real time. For clients with concerns about security of blue-tooth connections, a version of the SONUS PD is available without blue-tooth connectivity.
