The?primary current?generator is the necessary equipment for the electric power and electrical industry that needs?primary current?during commissioning. The device has the characteristics of convenient use and maintenance, superior performance, safe and reliable use, beautiful appearance and structure, sturdy and durable, and easy to move. It is the equipment for power supply enterprises, large factories, metallurgy, power plants, railways, etc. that need power maintenance departments, so what is the main purpose of the?primary current?generator? And what aspects should be paid attention to when using it? Today?HV Hipot?will give you a detailed answer.

The primary-current generator adopts advanced microelectronic processing technology, and the entire use process can be set in advance, with a full Chinese interface, and the operation is simple and clear. After all the test items are set, the test will be carried out automatically without manual intervention.

Precautions for use

1. There should be no less than two people in the testing work, one person operates and the other supervises the operation to ensure safety.

2. The casing must be grounded, and do not neglect the prevention of personal safety accidents because of low voltage. The instrument must be well grounded, and the step-up transformer and operating table must be reliably grounded in use to ensure safety.

3. The lead wire from the secondary of the current booster to the tested product should not be too long, and the cross-sectional area should be sufficient (the current density can be considered as 6-8A). The contact surface should be cleaned (can be brightened with fine gauze), otherwise the joint will heat up, and the current will even rise. Less than 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 the normal work.

5. There should be no flammables on the job site. Sufficient fire extinguishing equipment should be prepared for the temperature rise test.

6. For the continuity (heating) test, someone should be on duty at the site. And regularly check the heating conditions of the ascending current source equipment, wires, and connectors, and make records. Due to the fluctuation of grid voltage, pay attention to adjust TD in order to maintain the rated test current. During the test, once abnormal phenomena are found, the power supply of the air switch should be cut off immediately, and the test should be carried out after finding out the cause. After the test, the voltage regulator must be returned to zero, press the air switch to cut off the power supply, cut off the working power supply, and remove the test wiring in the direction to ensure safety.

7. The test work of the large current generator should abide by the relevant provisions of the safety work regulations of the electrical industry and formulate practical safety measures. The instrument is designed for short-term work, so it is not allowed to work under the rated capacity for a long time, especially not allowed to exceed the rated current to prevent overheating.
