Grounding Continuity TesterZC-413B

A reliable and effective connection between the grounding down-conductors of power equipment and the grounding 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 grounding grid; however, during the prolonged operation of power equipment, the connection points may be compromised by factors such as moisture, leading to issues such as contact corrosion or even breakage. This results in an increased resistance at the junction between the down-conductor and the main grounding grid, thereby failing to meet the requirements of relevant power regulations. Consequently, the equipment faces safety hazards during operation, and in severe cases, may suffer from a complete loss of grounding.
The ZC-413B 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. As such, it serves as an ideal specialized instrument that fully complies with regulatory requirements.
