  • Page 8 2388-MANUL-V13.04.00-UltraTEV Plus² Operating Manual General Description The UltraTEV ® Plus² (UTP2) is a versatile hand-held tool used to easily detect and classify Partial Discharge (PD) in a wide range of electrical equipment. The UTP2 uses inbuilt TEV and Ultrasonic sensors and external accessories to detect the presence of potentially damaging PD in switchgear, cables and overhead line equipment.
  • Page 9 2388-MANUL-V13.04.00-UltraTEV Plus² Operating Manual The most sensitive method of detection is using an airborne ultrasonic Microphone centred at 40 kHz. This method is very successful at detecting partial discharge activity provided there is an air passage between the source and the Microphone. Electromagnetic Discharge Activity When partial discharge activity occurs within high voltage switchgear, it generates electromagnetic waves in the radio frequency range which can only escape from the inside of the switchgear through openings in the...
