The Primary Current Injection Test Set is a necessary equipment in the power and electrical industries where high current is required during debugging. The device is equipped with a high-strength aluminum alloy chassis, which is convenient to use and maintain, superior in performance, safe and reliable in use, beautiful in structure, sturdy and durable, and convenient to move. And other characteristics; can output large current for a long time, and can also output the maximum value continuously for a short time.
To test thermal relays, switches, transformers, AC contactors, protection circuits, etc., directly measure the transformation ratio and polarity of CT, and switch action time, which is a destructive test for bad test products. It is necessary equipment for power supply companies, large factories, metallurgy, power plants, railways and other departments that need power maintenance.
Precautions for Primary Current Injection Test Set:
1. The stand-alone equipment is heavier; when testing and moving: pay attention to personal safety. The test work should not be less than two people, one person to operate, and one person to supervise the operation to ensure safety. The test personnel and the tested product should keep a corresponding safe distance. The test personnel wear protective gear and set up a warning area.
2. The shell must be grounded. Don't neglect to prevent personal safety accidents due to low voltage. The instrument must be well grounded, and the step-up transformer and the console must be reliably grounded during use to ensure safety.
3. The lead from the secondary to the tested product should not be too long, and the cross-sectional area should be sufficient and the contact surface should be cleaned (it can be brightened with fine gauze), otherwise the joint will heat up and the current will even fall below the rated value.
4. Before working, check that the power supply has sufficient capacity, otherwise the power cord will heat up and the voltage will drop, which will affect normal operation.
5. There should be no flammable materials at the work site. Sufficient fire extinguishing equipment should be prepared for the temperature rise test.
