In order to conform to the specified operating rules, the equipment design includes the following principle:

The product does not emit electromagnetic wave (electromagnetic compatibility). 

The product is not influenced by external electromagnetic interference (EMI).

The product is provided with electrostatic discharge (ESD) protection.

Product Technical Parameter1.Applicable scope: the non-intrusive mode is adopted to detect and locate the partial discharge defects of the high-voltage electric equipment.

2.Detection principle: UHF (Ultra High Frequency) method, UA (Ultrasonic Analysis) method and TEV (Transient Earth Voltage) method.

3.Detection frequency band: the UHF detection frequency band is 300~2000(MHz) and the ultrasonic detection frequency band is 20~200(KHz).

4.Measurement range: the UHF measurement range is -80~10dBm and the ultrasonic measurement range is -90~80dB.

5.Sensitivity: the minimum sensitivity is 10pC (specifically determined by the distance between the sensor and the discharge source).

6.Sensor:

a)UHF sensor: 300~2000(MHz), with directional reception characteristic;

b)Ultrasonic sensor: 20~200(kHz);

c)EV (Transient Earth Voltage) sensor: 5 ~ 100MHz.

7.Embedded ultrasonic sensor and TEV & UA integrated sensor: such components as transformer dedicated sensor, GIS dedicated sensor and cable dedicated sensor can be selected;

8.Software function:

a)Continuously detect UHF, TEV and ultrasonic signals to judge whether there is any partial discharge;

b)Display the variation tendency of the detected signal in a real-time manner to intuitionally judge the development of the partial discharge signal;

c)Field data storage function;

9.Instrument characteristics:
