Description
ZC-202A Transformer no-load & load tester can measure the transformer no-load current, no-load loss, short circuit voltage, short circuit (load) loss. Harmonic test can be carried out, analysis to the 31 harmonic. The instrument automatically switches the range, allowing the measurement of voltage, wide current range, simple wiring. Do three-phase transformer no-load, load test, the instrument can automatically determine whether the wiring is correct, and display the three-phase voltage, current vector.
Only need one tester can measure the load experiment under 1000kVA distribution transformer at full current; measuring the load test in 1/3 rated current can be completed under 3150KVA distribution transformers (in the 1/3 of the rated current under the instrument can be converted to the load loss parameters under the rated current). All test results are automatically corrected. The instrument can carry out many kinds of correction, such as waveform correction, temperature correction, non rated voltage correction, non rated current correction and so on.
