This is a high precision integrated test instrument, not only for checking out transformer capacity, but also for testing transformer performance such as no-load current, no-load loss, short-circuit voltage, short-circuit loss, impedance voltage, etc. It has high quality chargeable battery, one charge can last for 100 times test continuously. Internal digital synthesis standard sine wave (not contravariant AC output), can provide 3-phase precision AC test power, after being amplified. When measuring capacity and short-circuit loss, there don't need auxiliary equipments such as 3-phase test power, regulator and current-upgrading equipment. High accuracy rate of capacity test result, 100%! Big test range: Max. Voltage can be 750V! Automatically carry out wave distortion rectifying, temperature rectifying and voltage rectifying (no-load test under non-rated voltage), current rectifying (short-circuit under non-rated current).
