Interturn Overvoltage Tester

According to the provisions of "GB 1208-2006 Current Transformers", the transformers need to be subjected to a turn-to-turn overvoltage test.

The HMKL-H Interturn overvoltage tester is a special device for detecting the peak value of the open circuit voltage of the current transformer. This instrument adopts modular design technology. It adopts the mature and reliable peak detection circuit of the factory, and has a high impact resistance and anti-interference design. , To ensure the high reliability of this instrument.

This instrument can also measure the peak value of power frequency voltage, continuous pulse voltage peak, harmonics, etc. It is an instrument with a high cost performance.

The HMKL-H Interturn overvoltage tester is a portable instrument suitable for measuring voltage peaks in laboratories, workshops and other occasions.

The maximum test value of the HMKL-H Interturn overvoltage tester can reach 4500V (peak value).

The HMKL-H Interturn overvoltage tester has an overvoltage alarm function to avoid overvoltage damage to the experimental equipment.

HMKL-H Interturn overvoltage tester adopts 1024X768 large screen TFT color touch screen, which is more user-friendly operation.

The HMKL-H Interturn overvoltage tester has the 15th harmonic analysis function, which is a better analysis parameter for users.

LCD screen: 8-inch high-definition color touch screen, resolution 1024X768

Power consumption of the whole machine: <20W

The instrument must be grounded reliably;

The test voltage should not be higher than 6000V (peak value). Excessive voltage may damage the instrument.

There should be no source of strong magnetic field in the measurement site;

Please do not operate with electricity, turn off the power when wiring;

Do not touch the high-voltage input wire and input terminal during measurement.

When not in use, the instrument should be placed in a ventilated and dry place, protected from moisture, dust, and corrosion.

The turn-to-turn overvoltage tester and large current generator are integrated, which can meet the requirements of current transformer test voltage and up-current test.
