UHF PD Plate Sensor UHF-PS1

The UHF PD plate sensor is used for measuring of the electromagnetic radiation from internal PD in ultra-high frequency range (UHF) in transformers. It can be integrated directly into the tank wall at new transformers.

Cigré Working Group WG A2-27 recommends to install DN50 valves or dielectric windows for later fitting of UHF probes. (Recommendations for condition monitoring and condition assessment facilities for transformers, TB 343). The dielectric window of the UHF-PS1 sensor is designed according to Cigré Working Group WG D1-37 (Guidelines for partial discharge detection using conventional and unconventional methods, TB 662).

The sensor consists of a stainless steel welding ring, an oil-durable, temperature stable dielectric window and the UHF antenna, which is inserted into the dielectric window. Plate sensors are mainly used for continuous PD monitoring of transformers. Multiple sensors can be installed at a transformer.
