HZ-109S 1000A Primary Current Injection Test Set

Overview
The HZ-109S Primary Current Injection Test Set utilizes ARM chip control technology for output management and a high-capacity toroidal transformer. Equipped with an LCD display meter, it can simultaneously display the primary current, secondary current, turn ratio, and the actuation time of the stopwatch connection (electric potential). Housed in an external aluminum alloy case with a PC panel, the product offers a nice appearance, large output capacity, small size, and light weight. It is primarily suited for CT turn ratio tests, contact resistance tests, and other applications requiring high-current testing in power systems.

Safety Precautions
1. In order to ensure the safe operation of test, the instrument should be grounded reliably before the test.
2. The power supply voltage should be set as 220V±10%. Do not input 380V power supply into the instrument, or the instrument will be severely damaged.
3. Connecting or disconnecting the test wire is strictly prohibited when the test is conducting.
4. For the test set, the cable cross-section of input power should be greater than 2mm2, and the cable cross-section of high current output connection should be greater than 70mm2, and the cable length of the output connection should be kept as short as possible.
5. Use paralleling output wherever possible, if only the demand of output current is met.
6. Avoid continuous output in a long time.
