GD6900 Capacitance & Tan Delta Tester
• 7-inch touch LCD screen display.
• Calendar chip and large storage inside. Save testing result according to time order, check history record and print the result.
• The instrument data can be exported through U disk.
• The integrated insulation resistance test module can test polarization index, absorption ratio and insulation resistance.
• Multiple testing mode, with modes of internal high voltage, external high voltage, internal 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.
• 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.
• No need to dismantle cable to measure dielectric loss and capacitance of CVT.
• The dielectric loss and capacitance value of C0 in the upper end of CVT can be measured by using the reverse shielding method.
• High speed sampling signal. Inverter and sampling circuit inside are digitized controlled. Output voltage is adjusted continuously.
• LCR automatic measurement. Inductance, capacitance, resistance can be measured and displayed.
• 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.
• Frequency can be changed into 45Hz, 50Hz, 55Hz, 47.5Hz/52.5Hz, 45Hz/55Hz, 60Hz, 65Hz, 57.5Hz/62.5Hz, 55Hz/65Hz.
