The TKJF-208 hand-held partial discharge detector is used to detect the local discharge power supply in medium and high voltage equipment.If no discharge is detected it does not mean that there is no discharge activity in medium and high voltage equipment.Power discharges often have an incubation period and the insulation may fail for reasons other than partial discharge.If a significant discharge is detected in equipment connected to the medium-high voltage power system the equipment maintenance department should be notified immediately.

Optional: transformer special sensor network GIS specialUHF sensor high voltage cable special sensor can also be customized according to user requirements.

2.Detection principle: UA TEV and UHF

3.Detection frequency band:

               UA: 40～200KHz

              TEV: 3~100MHz

              UHF: 300～2000MHz.

5.Measurement range:

b)TEV (Transient Earth Voltage) sensor: 5 ~ 100MHz;

c) UHF sensor: 300～2000(MHz) with directional reception characteristic.

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

9.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 intuitively judge the development of the partial discharge signal;

c) Field data storage function;
