Simple operation, the instrument is equipped with a high-end full touch LCD screen, super touch interface, and each process is very clear. Operators can use it without additional professional training.
★Mass storage data
The instrument is equipped with a calendar chip and large capacity memory. The test results can be stored in chronological order. Users can view historical data at any time and print it out.
★Multiple test modes
The instrument can be tested by high pressure, high voltage, standard, positive connection method, reverse connection method, self excitation method and other methods.
★CVT test step in place
The instrument can also test the full sealed CVT (capacitor voltage transformer) C1, C2 dielectric loss and capacitance, to achieve the C1, C2 simultaneous test.
★Do not dismantle the high-voltage lead measurement CVT
The instrument can accurately measure the dielectric loss and capacitance of CVT without dismantling the CVT high voltage lead.
★CVT reverse shield method for measuring C0
The instrument can be used to measure the dielectric loss and capacitance value of C0 on the upper end of CVT.
★High speed sampling signal
The inverter and sampling circuit of the instrument are all controlled by digital, and the output voltage is adjustable continuously.
★Multi protection security
The instrument has many protection measures, such as input voltage fluctuation, output short circuit, over voltage, over current and temperature.
