1. Can **measure the capacity of various distribution transformers, passive measurement, convenient and accurate
2. Can measure the no-load current, no-load loss, short-circuit voltage, and short-circuit (load) loss of transformers
3. The instrument automatically switches ranges internally, allowing a wide range of voltage and current measurements, and simple wiring
4. When testing the no-load and load of three-phase transformers, the instrument can automatically determine whether the wiring is correct and display the vector diagram of three-phase voltage and current
5. A single unit can complete1000KVA and below distribution transformer load test measurement under full current; at one-third of rated current, it can complete
3150KVA and below distribution transformer load test measurement (at one-third of rated current, the instrument can convert to load loss at rated current
loss parameters)
6. All test results are automatically corrected. The instrument can automatically perform various corrections such as waveform correction, temperature correction, non-rated voltage correction, non-rated current
correction, etc., making the test results more accurate
