Description
l 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.
l It has high quality chargeable battery, one charge can last for 100 times test continuously.
l Internal digital synthesis standard sine wave (not contravariant AC output), can provide 3-phase precision AC test power, after being amplified.
l When measuring capacity and short-circuit loss, there don’t need auxiliary equipments such as 3-phase test power, regulator and current-upgrading equipment.
l High accuracy rate of capacity test result, 100%!
l Big test range: max. voltage can be 750V!
l 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).
l Large-size LCD displaying, menu operation
l Test data can be printed out at any time
