Performance characteristics
1. Power supply technology: The use of new power supply technology, output 5A current, can work continuously for a long time, overcome the drawbacks of the instantaneous current of the pulse power supply, can effectively break down the oxide film of the contact, and obtain good test results.
2. Strong anti-interference ability: under severe interference conditions, the last data of the LCD screen can be stabilized within the range of ±1 word, with stable reading and good repeatability.
3. Long service life: the use of high-precision resistance, effectively eliminate the impact of ambient temperature on the measurement results, while the use of to enhance the anti-vibration performance.
4. Simple operation: Just press the measurement key to get the measurement result. The measurement results are displayed by LCD backlight, with intuitive reading and good repeatability.
5. Easy to carry: portable design, small size, light weight. The panel is integrated with the chassis, which has good shock resistance.
The electrical integrity of the grounding device refers to the electrical connectivity between various electrical equipment, parts of the grounding device and the equipment that should be grounded in the grounding device, that is, the direct current resistance value, also called electrical conductivity. The reliable and effective connection between the ground lead line of power equipment and the ground network is the fundamental guarantee for the safe operation of the equipment.

The ground lead down is the connection between the power device and the ground network. During the long-term operation of the power device, node corrosion or even fracture may occur at the connection point due to factors such as moisture. As a result, the resistance between the ground lead down line and the connection point of the main ground network increases, which fails to meet the requirements of the power regulations and causes unsafe risks in the operation of the device. In serious cases, the equipment will lose ground operation. The underground grounding electrode of the grounding device and its connecting part may also rust or even break.
The power industry standard DL/T475-2006 "Guidelines for the Measurement of Characteristic Parameters of Grounding devices" stipulates that the electrical conductivity should be measured by a special instrument with a resolution of 1mΩ and an accuracy of not less than 1.0.
KDDT-5A ground lead down conduction tester developed by our company according to this standard is a portable tester with a high degree of automation, which is specially used for the electrical integrity test of grounding devices, and its technical indicators meet or better than the relevant standards. The instrument has the advantages of simple and convenient operation, high precision, fast test speed, good retest and intuitive reading. It is an instrument that meets the requirements of the regulations, which greatly facilitates the development of the test project and improves the work efficiency.
