Product Introduction

With the development of power system, the capacity of running equipment is increasing. For example, Thermal generator group, the single capacity has exceeded 1000MW, and hydrodynamo group, the maximum capacity has reached 800MW. If traditional test equipment (power frequency test transformer) is used for the ac power frequency withstand Voltage test of these devices, the regulator is very bulky because of the large test capacity required, and the high-capacity test power supply is difficult to solve in the field, so the field test is extremely inconvenient. The Power frequency withstand voltage tester host, no matter from test Power supply capacity, equipment weight, the waveform and has advantages in such aspects as investment. The Power frequency withstand voltage tester host focuses on the potential of capacity of 250 mw and below hydrodynamo ac withstand voltage test of the design and manufacture.
