GD6800 measures the capacitance and dielectric loss factor (tgδ) of high voltage electric equipment. It is integrated structure, built-in dielectric loss test bridge, variable frequency adjustable power supply, boosting transformer and SF6 standard capacitor. Test HV source is generated by anti-transformer inside instrument, which is boosted via transformer then is used for test object. Frequency can be changed into 50Hz, 47.5Hz52.5Hz, 45Hz55Hz, 60Hz, 57.5Hz62.5Hz, 55Hz65Hz.
- 1. Touch LCD screen display.
- 2. Massive data storage
- 3. Scientific advanced data management
- 4. Multiple testing mode, with modes of inside high voltage, outside high voltage, Inner standard, external standard, GST/UST, self-excitation. High voltage(more than 10kV) dielectric loss test can be made in the situation of external standard outside high voltage.
- 5. Test full sealed CVT(Capacitive Voltage Transformer) C1 and C2 dielectric loss and capacitance at the same time. Also test CVT transformation ratio and voltage angle difference.
- 6. No need to dismantle cable to measure dielectric loss and capacitance of CVT.
- 7. The dielectric loss and capacitance value of C0 in the upper end of CVT can be measured by using the reverse shielding method.
- 8. High speed sampling signal. Inverter and sampling circuit inside are digitized controlled. Output voltage is adjusted continuously.
- 9. Multiple protection of input voltage fluctuation, output short circuit, over-voltage, over-current, temperature, secure and reliable. Meanwhile, it has the function of grounding testing, that voltage boost is not permitted for non-grounding equipment.
