Prodcut Features
The product conforms to the following applicable regulations:
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:
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: -25ºC~45ºC.
h)Storage temperature: -35ºC~60ºC.
10.Complete configuration: host machine, sensor, AC adapter, connecting cable and transport case.
