HZJF-9008 cable partial discharge test kit equipment of generator

1.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:

a)Screen display: high-contrast 3.5"TFT color screen.

b)Data storage: 4000 groups of test data can be stored.

c)Working power supply: embedded 8.4V lithium battery for 8h's continuous operation.

d)Power supply: input 100-240VAC, output 8.4V/3A, charging time 3~4h.

e)Boundary dimension: 220 * 100 * 40.

f)Instrument weight: 1.5kg.

g)Environment temperature: -25℃~45℃.

h)Storage temperature: -35℃~60℃.

10.Complete configuration: host machine, sensor, AC adapter, connecting cable and transport case.
