OWTS MV series cable oscillation wave partial discharge test system
The Cable Oscillator Offset Test System (OWTS) is a device for the partial discharge test of cross-linked polyethylene power cables. For field testing, DC power supply is not suitable for XLPE power cables, and ultra-low frequency (0.1Hz) power supply is used because of the large capacity of the power cable. It is difficult to test the power supply voltage. New flaws. Cable oscillation wave partial discharge detection and positioning technology, is the use of the cable itself, the capacitance characteristics of the attenuation of the oscillation of the AC high-voltage waveform, the power supply equipment is light, and can effectively detect and locate the location of the cable part of the discharge without causing damage to the cable, More widely used.
OWTS MV series cable oscillation wave partial discharge test system is developed by Ningbo Science and Technology Monitoring Technology Co., Ltd. for the detection, positioning and evaluation of cable insulation and accessories in the partial discharge fault products for different voltage levels of low voltage power cable PD test.
