SXHGQ-H automatic high-voltage three-phase combined

SXHGQ-H automatic high-voltage three-phase combined transformer calibration station, also known as transformer calibration station, transformer calibration device, transformer calibration device, transformer detection device, SXHGQ-H automatic

The combined transformer verification device changes the current traditional single-phase inspection method, realizes the verification of the combined transformer, meets the requirements of the current national standards and industry standards (test guidelines), and is easy to implement

Inspection, it does not require multiple wiring tests in the current single-phase method, which can save a lot of manpower and material resources and improve work efficiency. It consists of a combination of transformer error data management software, transformer calibrator,

It is composed of voltage and current load box, electronic power source and standard transformer. RS485 communication is adopted between the components to realize the automatic verification of the multi-phase voltage and current of the three-phase combined transformer in turn.

It is suitable for measurement and test centers of power grid companies, power management and measurement departments of power supply companies, national measurement and test institutions at all levels, and large industrial and mining enterprises.
