Dielectric Loss Tester

Darui Electric recommends



I. Product Features:

1. Simple operation

2. Chinese display, printing, easy to use, no conversion needed, built-in high voltage

3. Strong anti-interference capability

4. Short test time, etc.

II. Product Introduction:

The dielectric loss tester is an instrument for measuring dielectric loss and capacitance. It is used to measure the dielectric loss and capacitance of various insulating materials, insulating bushings, power cables, capacitors, transformers, and other high-voltage equipment under power frequency high voltage. It replaces the QSI high-voltage bridge and has advantages such as simple operation, Chinese display, printing, easy use, no conversion needed, built-in high voltage, strong anti-interference capability, and short test time. It is the third-generation intelligent dielectric loss tester of our company.

Structure of the dielectric loss tester: It adopts an integrated structure of voltage boosting and measurement, with output voltage adjustable in five gears from 2.5KV to 10KV to meet various needs. No external equipment is required during measurement. The wiring is similar to that of the QSI bridge but more convenient.

Principle of the dielectric loss tester: The standard circuit consists of a built-in high-voltage stable standard capacitor and a standard resistor network. The computer collects the current amplitude and phase difference of the standard circuit and the test circuit in real time, and calculates the capacitance and dielectric loss of the tested object.

3. Power supply: Voltage: 220V±10%, frequency 50±1Hz

4. Dimensions: Length*Width*Height = 440mm*295mm*360mm

5. Weight: 22.5kg

6. Output power: 1.5KVA

7. Display resolution: 3 digits, 4 digits (internally all 6 digits)

8. Test methods: positive connection method, reverse connection method, external test voltage method

9. Measurement range: Internal test voltage: ≤60000PF (greater than 30000PF at 10KV voltage)

           External test voltage: determined by the output power of the external test transformer

10. Basic measurement error:

       Dielectric loss (tgδ): 1%±0.04%

       Capacitance (Cx): 1%±1pF
