UHF partial discharge detector
WS-CJF-UHF-100
WS-CJF-UHF-100 UHF partial discharge detector relies on electromagnetic wave spatial positioning technology to detect electromagnetic wave signals generated by partial discharge excitation through an omnidirectional UHF sensing antenna.It can receive leaked partial discharge electromagnetic wave signals in space over a wide range (radius 20m), and is used to monitor the operating status of the entire substation/distribution station and cable equipment. The effective monitoring and fault location distance is 5-20 meters.The detection bandwidth is 300MHz ~ 2000MHz, which is a UHF detection method. The bandwidth is better than traditional UHF sensors. The omnidirectional electromagnetic baud high-frequency antenna does not require surface-mounted installation and is open to the environment to be monitored. It is better than traditional ones in operation. The product is safe and does not have any impact on primary equipment.The test results can be viewed on-site through a network cable connected to the host to view real-time monitoring charts (PRPD and PRPS charts). Customers can choose the viewing method.
Main functions and characteristics

1) Strong anti-interference ability and high precision (5pc);

2) Real-time online monitoring (24 hours), maintenance-free, and operation time can reach 10 years;

3) Highly integrated, simple appearance, strong environmental adaptability, using non-contact omnidirectional electromagnetic wave spatial positioning detection technology, without contacting the equipment, it can achieve 360-degree non-dead-angle monitoring of equipment partial discharge, and the monitoring radius is up to 20 meters.
