| Overview
1. Purpose HZ5374 primary current injection tester, referred to as (upper) is a test equipment developed by our company. It combines the advantages of similar products at home and abroad. It adopts numerical control technology and has strong anti-interference ability. Compared with the previous generation up , due to the low power consumption, large capacity self-coupling voltage regulator and the converter made of high magnetic permeability iron core, it has the advantages of large output power, small size and light weight. It is mainly used for primary busbar protection and various current transformer transformation ratio test items, and is widely used in scientific research, production and electrical test sites of electric power, railway, petrochemical, metallurgical and mining enterprises. 2. Performance characteristics, Beautiful and generous PVC panel Directly display the test value of primary current and secondary current, which is convenient for test observation and recording. Secondary measurement of the transformer, transformation ratio, and polarity are displayed at the same time High measurement accuracy 0.5 level Large power, small size, strong load capacity Small in size and light in weight, the volume is only 30% to 70% of similar products, and it is very convenient to carry. |
