HZ5376 6000A Primary Current Injection Test Set

Huazheng HZ5376 6000A Primary Current Injection Test Set is an independently developed testing device. It integrates the strengths of similar domestic and international products, utilizing numerical control technology with strong anti-interference capabilities.
Compared to previous generation models, it features a low-power, high-capacity variable autotransformer and a current transformer with a high-permeability iron core. This design delivers advantages including high output power, compact size, and light weight.
It is primarily used for calibrating thermal relays, motor protectors, contactors, circuit breakers, air switches, switchgear cabinets, and protective screens.
It is also applicable for testing projects such as the ratio of primary busbar protection and various current transformers.
The device is widely used in scientific research, production, and electrical testing sites across multiple industries, including power, railway, petrochemical, metallurgy, and mining.

Main Functions

Can instantaneously output a current of 0～6000A.

The timer stops timing when the current is disconnected.

Can synchronously test the action time of equipment.

Automatically identifies normally open and normally closed contacts.

Can connect multiple calibration devices in series simultaneously to improve work efficiency.

Operational Aspects

(1) After completing the wiring, check it again to ensure there are no wiring errors and that the connectors are in good contact.

(2) During the testing process, if abnormal phenomena such as arcing or no display upon startup occur, immediately turn off the power and recheck the wiring.

(3) In actual wiring, the current output terminals should form a loop; otherwise, the instrument will not output current.

(4) This current booster comes with random output leads; the external copper output leads should be selected according to 10A/mm². (The standard configuration includes two 1-meter test leads.)

(5) The equipment's capacity temperature rise (30 minutes - 24 hours) is configured according to the long-term working temperature rise.
