The instrument adopts self-made precision three-phase inverter power supply, which has high and low voltage reverse connection protection, transformer inter-turn short circuit protection, tap switch failure protection, and output full short circuit protection, which increases the stability of the instrument. After inputting the rated parameters, the transformer ratio, error value and tap position of the tap changer can be automatically measured, especially for the tap changer with asymmetrical taps, the exact position of the transformer tap changer can also be accurately measured. Tap changer with 99 tap points.
The instrument adopts a 7-inch high-definition color touch screen LCD, with modular display. Each operation step has Chinese prompts. No manual is required, and the instrument operation can be completed only by looking at the LCD prompts. And the measurement data can be printed by an external printer, which is convenient for paperless office.
