GD6900 Capacitance & Tan Delta Tester
題-113.jpg)
? 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.
