The electrical integrity of the grounding device refers to the grounding device should be grounded between the various electrical equipment, the grounding device of the various parts and the electrical connectivity between the equipment, that is, the DC resistance value, also known as electrical conductivity. Power equipment grounding lead wire and ground network is reliable, effective connection is the fundamental guarantee of the safe operation of the equipment. Grounding lead is the connection part of the power equipment and ground network, in the long operation of power equipment, the connection may be affected by moisture and other factors, node corrosion, or even fracture and other phenomena, resulting in increased resistance of the grounding lead and the main grounding network connection point, which can not meet the requirements of the electric power regulations, so that the equipment in the operation of the existence of insecure hidden danger, will cause serious equipment out of ground operation. Grounding device underground grounding electrode and its connection part may also appear corrosion, or even fracture phenomenon. Therefore, regular electrical integrity testing of grounding devices is necessary.
Power industry standard DL/T475-2006 "Measurement Guidelines for Characteristic Parameters of Earthing Devices" stipulates that the electrical conductivity should be measured by a specialized instrument with a resolution of 1mΩ and an accuracy of not less than 1.0 level.The instrument developed by our company according to the standard is a portable tester with high degree of automation, which is specially used for the electrical integrity test of grounding device, and its technical indexes have reached or are better than the requirements of relevant standards. The instrument is easy and convenient to operate, high precision, fast test speed, good re-testing, intuitive readings, is the ideal special instrument in line with the requirements of the regulations, which greatly facilitates the development of the test program and improves work efficiency.
1. Power supply technology:adopting the latest power supply technology,output 10A current,canwork continuously for a long time,overcoming the drawbacks of instantaneous current of pulse power supply,which can effectively penetrate the contact oxidized film andget good test results.
2. Strong anti-interference ability:under serious interference conditions,the last data of the LCD screen can be stabilized within the range of±1 word,stable reading and good repeatability
3. Long service life:All adopt high-precision resistors,effectively eliminating the influence of ambient temperature on the measurement results,while the use of connectors enhancesthe anti-vibration performance.
4. Simple operation:just press the measurement key to get the measurement result.Measurement results are displayed by LED,intuitive reading,good repeatability.
