HZ-109S 1000A Primary Current Injection Test Set
Overview
The HZ-109S Primary Current Injection Test Set is a compact yet powerful instrument designed for high-current testing applications in power systems. At its core, the device utilizes ARM chip control technology for precise output management, complemented by a high-capacity toroidal transformer that delivers stable and reliable current generation.
The instrument is equipped with an LCD display meter that simultaneously shows primary current, secondary current, turn ratio, and the actuation time of the stopwatch connection (electric potential), providing operators with comprehensive real-time test data at a glance.
The HZ-109S is housed in an external aluminum alloy case with a PC panel, offering a sleek and professional appearance while ensuring durability. Despite its large output capacity, the unit maintains a compact footprint and light weight, making it highly portable for field use.
The test set is primarily suited for CT turn ratio tests, contact resistance tests, and other power system applications requiring high-current testing.

Safety Precautions
Grounding: To ensure safe test operation, the instrument must be reliably grounded before testing.
Power Supply Voltage: The power supply voltage must be set to 220 V ± 10%. Do not apply 380 V power to the instrument, as this will cause severe damage.
Test Wire Connection: Connecting or disconnecting test leads is strictly prohibited while the test is in progress.
Cable Cross-Section Requirements: For the test set, the input power cable cross-section should be greater than 2 mm², and the high-current output connection cable cross-section should be greater than 70 mm². The output connection cable length should be kept as short as possible.
Parallel Output: Use parallel output whenever possible, provided it meets the output current requirements.
Continuous Output: Avoid prolonged continuous output operation.
