Huazheng Electric HZ5375 5000A Primary Current Injection Test System

1.purpose

HZ5375 5000A Primary Current Injection Tester (referred to as upconverter), our own self-developed test equipment, it combines the advantages of similar products at home and abroad, using CNC technology, strong anti-interference ability, compared with the previous generation upconverter Because of the use of low-power, large-capacity self-coupling voltage regulator and high permeability iron core converter, it has the advantages of large output power, small size and light weight. Mainly used in primary bus protection and various current transformer transformation ratio test projects, it is widely used in electric power, railway, petrochemical, metallurgy and mining companies such as scientific research, production and electrical test site.

2.Performance characteristics
