BL-830 Partial Discharge Tester

Technical Specifications

    ● Applicable scope: the non-intrusive mode is adopted to detect and locate the partial discharge defects of the high-voltage electric equipment;

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

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

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

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

    ● Sensor:

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

      2. Ultrasonic sensor: 20～200(kHz);

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

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

    ● Software function:

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

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

      3. Field data storage function;

    ● Instrument characteristics:

      1. Screen display: high-contrast 3.5"TFT color screen;

      2. Data storage: 4000 groups of test data can be stored;
