JF-2004 Portable Transformer Partial Discharge Detector

JF-2004 Portable Transformer Partial Discharge Detector

Introduction:

• Application: non-intrusive detection methods to detect and locate partial discharge defects in high-voltage electrical equipment.

• Working principle: Ultra-high frequency method (UHF), ultrasonic method (UA) and terrestrial electric wave method (TEV).

• Detection frequency range: UHF is 300～1500(MHz), ultrasonic is 20～200(KHz).

• Measuring range: UHF is -80～-20dBm, and ultrasonic is 0～90dB.

• Sensitivity: 10pC minimum (depending on the distance between the sensor and the discharge source).

Sensor:

JF-2004 Partial Discharge Detector has a built-in ultrasonic sensor, a two-in-one sensor for geo-electric wave and ultrasonic;

1. UHF sensor: 300～2000(MHz), with directional receiving characteristics;

2. Ultrasonic sensor: 20～200(kHz);

3. Earth electric wave (TEV): 10 ~ 70MHz;

Software function:

1. Continuously detect ultra-high frequency, terrestrial electric wave and ultrasonic signals to determine whether there is partial discharge;
2. Real-time display of the change trend of the measured signal, which can make a more intuitive judgment on the development of the partial discharge signal;
3. Have on-site data storage function.
