Partial Discharge Detector XDP-013-014

The Differential Sensor with Double Spatula allow reducing ambient noise and handling when measuring partial discharge on MV/HV cable elbows. The sensor is used with the XDP, an online Partial Discharge Detection System for underground cable accessories and equipment for security/maintenance purposes.

The XDP-014 has been specially designed for cable elbows (XLPE/EPR type of insulation). Both spatulas are installed on the elbow to locate partial discharge activities. It has been designed taking into consideration the different cable geometry of an elbow to give the most accurate value. The sensor provides the level of noise, in dB. The sensor also gives the result of the subtraction of both values in a way to reduce significantly the ambient noise habitually present.

Advantages:

• On-line Partial Discharge Detection.
• Eliminates the ambient noise by a factor of 3 to 5 to allow the detection of a problem even in a noisy environment.
• Easy to handle.
• Detects any problems having a relative value in dB higher than the ambient noise.
