High Voltage Switchgear Partial Discharge Tester 

High Voltage Switchgear Partial Discharge Tester Features

• Built-in imported ultrasonic sensor; electrical faults generate ultrasonic waves at the fault point. In ultrasonic mode, listen to partial discharge ultrasonic signals through headphones, scan an area using the leak detection method, and various characteristic vibration sounds, popping sounds, and buzzing sounds can be associated with different faults.


• Built-in high-precision TEV sensor, couples electromagnetic signals generated by partial discharge to identify potential internal discharge fault risks.


• In Ultrasonic Mode, the main interface displays partial discharge amplitude (dBuv), using yellow, green, and red colors to indicate the severity of partial discharge; the headphone volume (Vol) can also be adjusted.


• In Transient Earth Voltage (TEV) Mode, the main interface displays partial discharge amplitude; the number of pulses per power frequency cycle, total pulse count, and discharge intensity level.


• Powered by rechargeable lithium battery, ensuring continuous operation for more than 6 hours.


• The interface uses true color LCD with real-time battery level indication; physical membrane keys are simple to use and equipped with external high-fidelity noise-canceling headphones.
