20A Portable Grounding Conductivity Tester

Product Introduction

，It refers to the electrical connectivity between various electrical equipment that should be grounded in the grounding device, as well as between each part of the grounding device and each equipment, that is, the DC resistance value, also known as electrical conductivity. The reliable and effective connection between the grounding down conductor of power equipment and the grounding grid is the fundamental guarantee for the safe operation of the equipment. The grounding down conductor is the connecting part between power equipment and the grounding grid. During the long-term operation of power equipment, the connection may be affected by factors such as moisture, resulting in node corrosion or even breakage, which increases the resistance of the connection point between the grounding down conductor and the main grounding grid and cannot meet the requirements of power regulations. This poses a safety hazard to the equipment during operation, and in severe cases, it may cause the equipment to lose ground and operate. The underground grounding electrode and its connecting parts of the grounding device may also experience rusting or even breakage. Therefore, it is necessary to regularly conduct electrical integrity tests on grounding devices using grounding downlead continuity testers.

Performance characteristics

1. Power technology: Adopting the latest power technology, it outputs 10A current and can work continuously for a long time, overcoming the drawbacks of instantaneous current in pulse power supply. It can effectively penetrate the contact oxide film and obtain good test results.

2. Strong anti-interference ability: Under severe interference conditions, the last bit of data on the LCD screen can remain stable within ± 1 word range, with stable readings and good repeatability.

3. Long service life: All use high-precision resistors, effectively eliminating the influence of environmental temperature on measurement results. At the same time, the use of Jun connectors enhances the anti vibration performance.

4. Easy to operate: simply press the measurement button to obtain the measurement result. The measurement results are displayed using LCD backlight, with intuitive readings and good repeatability.

5. Convenient to carry: Adopting a portable design, it has a small size and light weight. The panel and chassis are integrated into a structure, which has good seismic resistance.
