The IRISS Sonus PD is a family of handheld instruments designed for detecting partial discharge (PD) activity in medium and high voltage switchgear. PD is a type of electrical discharge that occurs within insulation due to defects or deterioration. It can be a precursor to catastrophic equipment failure, so early detection is crucial for preventive maintenance.
There are two main models in the Sonus PD family:

Sonus PD Family:
- Sonus PD Pro: This is the more advanced model, offering four operational ranges for PD detection, live level and scatter plot screens for data visualization, and advanced noise rejection for accurate results in even noisy environments. It can also detect airborne emission (AE) in addition to TEV signals.
- Sonus PD-X: This is a more basic model, but it still offers three operational ranges, a live level screen, and basic noise rejection. It is a good option for users who need a more affordable PD detector or who do not need the advanced features of the Sonus PD Pro.
Methods for Detecting:
- Transient Earth Voltage (TEV) detection: TEVs are small voltage pulses that are generated by PD activity and travel along the surface of the equipment. The Sonus PD uses capacitive sensors to pick up these TEVs.
- Ultrasound detection: PD activity can also generate high-frequency sound waves. The Sonus PD uses a piezoelectric sensor to detect these sound waves.
Benefits:
Here are some of the benefits of using the IRISS Sonus PD:
- Early detection of PD activity:Â This can help to prevent catastrophic equipment failure and save money on repairs.
- Improved maintenance planning: By knowing the condition of your equipment, you can plan your maintenance activities more effectively.
- Reduced risk of safety hazards: PD activity can lead to arcing and fires, so early detection can help to reduce the risk of these hazards.
If you are looking for a reliable and easy-to-use PD detector, the IRISS Sonus PD is a great option.
