Primary Current Injection Tester

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.

A Primary Current Injection Tester is an essential tool for electrical engineers and technicians. It plays a vital role in maintaining the safety and reliability of electrical systems by ensuring that protective devices function correctly under fault conditions.The  HZ5376 High Current Generator (hereinafter referred to as the current booster) is a testing equipment independently developed by our company.

A Primary Current Injection Tester is a specialized device used in the electrical engineering field to test and verify the performance of protective relays, circuit breakers, and other electrical equipment. This testing method involves injecting a high current directly into the primary circuit of the device under test, allowing engineers to assess its operational integrity and response to fault conditions.

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.

Adopted technology of ARM chip controlling output and toroidal transformer with high-capacity and equipped with LCD display meter, the HZ-109S2 Primary Current Injection Tester could simultaneously display primary current, secondary current and turn ratio. The product possesses the characteristics of nice appearance, large output capacity, small size, light weight and so on with external aluminum alloy case and PC panel. It is mainly suited for CT turn ratio and contact resistance tests of power system and other occasions needed high current test.

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.
