This device is applicable to the test of no-load & load & capacity of 30 ~ 2500kvA distribution transformer under the high current. At the same time in the absence of an external AC power conditions, the instrument provides an internal low-voltage three-phase sine wave inverter testing power supply, transformer capacity can be tested.In accordance with IEC standards IEC 61010-1. Safety requirements for electrical equipments  used in measurement, control and laboratory.

 (1) Carry on no-load & load test of 30～2500KVA transformer under high current; After the load test, it can carry on the judgment of transformer capacity and transformer type.
  (2) Transformer capacity can be automatically tested through the internal testing power supply.
  (3) To facilitate the measurement, it can be used for the testing of transformer capacity in the non-rated tap.
  (4) Instrument can determine power transformers capacity of a full range , S2, S7, S9, S11 type 10KV and 35KV voltage level and so on, and can determine 10KV level 630 ~ 6300KVA high voltage power transformers and the anti-high-voltage power transformers.
  (5) Save 15 transformers of rated capacity to judge the results and no-load, load test records and parameters, power down is not lost.
