Grounding Continuity TesterZC-413

A reliable and effective connection between the grounding down-conductors of power equipment and the ground grid serves as the fundamental safeguard for the equipment’s safe operation. The grounding down-conductor acts as the connecting link between the power equipment and the ground grid; however, during the equipment’s prolonged operation, factors such as moisture exposure may cause corrosion or even fracture at the connection points. This leads to an increased contact resistance between the down-conductor and the main ground grid, thereby failing to meet the requirements of relevant power regulations. Consequently, the equipment harbors potential safety hazards during operation, and in severe cases, may result in the equipment operating without a proper ground connection.
The ZC-413 Grounding Continuity Tester is a highly automated, portable testing instrument developed by our company for measuring the continuity resistance values ​​of grounding down-conductors associated with various power equipment within substations. Controlled by a high-performance microcontroller, the instrument features an intelligent testing process. It is characterized by its compact size, portability, simple operation, high accuracy, rapid testing speed, excellent repeatability, and intuitive display readings, making it an ideal specialized instrument fully compliant with regulatory requirements.
