Feature:

HCCT-H Current Transformer Field Tester with recursive method to measure current transformer error, as well as potential difference method to measure voltage transformer error function, convenient for carrying out calibration work of field metering device.

HCCT-H Current Transformer Field Tester without using Standard Current Transformer, Current Source, Load Box, Double Adjustable Control Box and Primary cable, using extremely simple test connection and operation to realize the current transformer test, greatly reduce work intensity and improve the work efficiency, convenient to carry out current transformer field test work.

The interior of HCCT-H Current Transformer Field Tester is equivalent to the measured current transformer with the same ratio of the standard voltage transformer, the accuracy can reach 0.05S, measure accurately the ratio of measured current transformer and load error. Then combined with the impedance and admittance test results to deduce the transformer error.

It adopts variable frequency power supply test which close to the power frequency, preventing the field power frequency electromagnetic radiation and series interference.

Measurement range is wide, can reach to 5A/5A~25000A/5A or 5A/1A~5000A/1A.

It has the function of current transformer ratio, secondary winding resistance test.

It adopts 800×600 high resolution and large screen liquid crystal display, has humanization interface and operation design, uses touch screen for auxiliary operation, make the operation more convenient and swift.
