Primary Current Injection Tester

The HZ-109S Primary Current Injection Tester adopts ARM chip technology for controlling output and a high-capacity toroidal transformer, and is equipped with an LCD display meter. It can simultaneously display primary current, secondary current, turn ratio, and the actuation time of the stopwatch connection (electric potential). The product features a sleek design, large output capacity, compact size, and lightweight construction, with an external aluminum alloy case and PC panel. It is primarily suited for CT turn ratio and contact resistance testing in power systems, as well as other applications requiring high current testing.

The HZ-5371L High Current Generator (referred to as the "current riser") is a test device developed by our company. It combines the advantages of similar products both domestically and internationally. Utilizing numerical control technology, it offers strong anti-interference capabilities. Compared to the previous generation of current risers, it features low power consumption, a large-capacity auto-regulator, and a high-permeability core converter, resulting in high output power, compact size, and lightweight construction.

HZDL 130 Primary Current Injection Tester(referred to as the current booster), our company's own research and development equipment, it combines the advantages of similar products at home and abroad, using CNC technology, strong anti-interference ability, compared with the previous generation of current riser Due to the low power consumption, large capacity self-twisting voltage regulator and high magnetic permeability core made of converter, it has the advantages of large output power, small size and light weight. It is mainly used for testing of busbar protection and various current transformers. It is widely used in research, production and electrical test sites of power, railway, petrochemical, metallurgical and mining enterprises.
