FAQs:

Q:What is the UHV-8003 Handheld Ultrasonic Partial Discharge Detector? 

A:The UHV-8003 is a portable partial discharge detection instrument designed to detect and analyze partial discharge signals from high-voltage electrical equipment. It can be used for equipment such as transformers, GIS, motors, cables, insulators, and overhead lines.

Q:What is partial discharge (PD)? 

A:Partial discharge is a localized electrical discharge that occurs in part of an insulation system without completely bridging the insulation between conductors. Continuous or severe partial discharge may indicate insulation defects and can contribute to insulation deterioration.

Q:Can the UHV-8003 perform non-invasive testing? A:Yes. The product uses a non-invasive detection method and is designed to detect partial discharge without requiring an additional high-voltage test source. According to the manufacturer's product information, certain detection applications can be performed without shutting down the equipment.
