Transformer Capacity and Load Loss Tester is mainly used to test capacity, No-load current, No-load loss, short circuit(load) loss, impedance voltage for transformers.
Features
Measure the capacity of various distribution transformers, which is convenient and accurate.
Measure transformer No-load current, No-load loss, short circuit voltage and short circuit(load) loss.
Automatic range switching is carried out inside the instrument, which allows a wide range of voltage and current measurements and simple wiring.
When making three phase transformer No-load and load test, the instrument can automatically judge whether the wiring is correct or not, and display the vector diagram of three-phase voltage and current.
Finish load test under 1000kVA below distribution transformer full current for single machine. Finish 3150kVA below distribution transformer load test under 1/3 rated current (Under 1/3 rated current, the instrument can be converted to load loss parameters under rated current.)
All test results are corrected automatically. The instrument automatic correction as follows, waveform correction, temperature correction, non-rated voltage correction and non-rated current correction. The test results are more accurate.
