● Touch LCD screen display.
● Insulation resistance measurement: Built-in insulation resistance test module, can carry out Insulation resistance (IR), absorption ratio (DAR), polarization index (PI) test.
● 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.
● 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.
● 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.
● 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, angle 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.
● No need to dismantle HV lead to measure dielectric loss and capacitance of CVT.
● Frequency can be changed into 50Hz, 47.5Hz/52.5Hz, 45Hz/55Hz, 60Hz, 57.5Hz/62.5Hz, 55Hz/65Hz.
