Product Introduction

The HCJDR-30A Grounding Wire Group DC Resistance Tester was developed in accordance with the *Regulations for Preventive Testing of Electric Power Safety Tools and Equipment*. It is designed to assess the quality of the electrical contact between grounding wire lugs (terminals) and busbar clamps, and the multi-strand flexible copper conductors to which they are connected.

The HCJDR-30A Grounding Wire Group DC Resistance Tester employs the DC voltage-current ratio method and consists of several components, including a low-voltage, high-current constant current source and a measurement system. The constant current source utilizes advanced switching power supply technology, characterized by its strong anti-interference capabilities and high stability. The measurement section features an intuitive, high-brightness digital display meter, ensuring accurate and reliable measurements, while the circuit selection and switching operations are flexible and convenient.
