Built-in PD Sensor

Name: Built-in PD Sensor
Brand: AUPINS TECHNOLOGY CO., LTD.

Ultra-high frequency (UHF) partial discharge detection technology is a technique used to monitor partial discharge phenomena in high-voltage electrical equipment. When partial discharge occurs within the insulation of power equipment, due to its high insulation strength and breakdown field strength, steep pulse currents are generated, which excite electromagnetic waves with frequencies up to several gigahertz. UHF partial discharge detection is based on this principle, utilizing UHF sensors to receive these ultra-high-frequency electromagnetic wave signals, thereby obtaining relevant information about the partial discharge.

FEATURES

Features of Built-in PD Sensor

Strong anti-interference ability

The detection frequency band is relatively high, which can effectively avoid various electrical interferences such as corona and switching operations in conventional partial discharge measurements

High detection sensitivity

It has a wide detection bandwidth, so its detection sensitivity is very high

Positioning capability

It can identify fault types and locate faults

High security

The ultra-high frequency (UHF) method uses spatial coupling of radio frequency signals via an antenna to eliminate the electrical connection between the monitoring system and the object being monitored, thus providing greater safety for operators and monitoring equipment.
