NRDT-10A Ground Conductor Continuity Tester_Wuhan NANR Electric Co., Ltd

Electric power industry standard DL/T475-2006 "Guide for measurement of grounding connection parameter" stipulates that electrical continuity should be measured with a special instrument with a resolution of 1mΩ and an accuracy of not less than 1.0%. NRDT-10A grounding conductor continuity tester developed by our company based on this standard is a portable tester with a high degree of automation. It is applicable to continuity resistance test between the grounding conductor of power equipment and grounding grid (or adjacent equipment), and is also applicable to the measurement of low resistance. Its technical indexes meet or exceed the requirements of relevant standards. The instrument has the advantages of simple and convenient operation, high precision, fast test speed, good retestability and intuitive reading. It is an ideal special instrument that meets the requirements of the specification, which greatly facilitates the development of test items and improves the work efficiency rate.

Product Characteristics

● Power supply technology: it adopts the latest power supply technology outputs 10A current can work continuously for a long time overcomes the disadvantages of instantaneous current produced by pulse power supply can effectively break through the oxide film of contact and obtain good test results.
● Strong anti-interference ability: Under severe interference conditions the last digit of the LCD screen can be stabilized within ±1 words with stable readings and good repeatability.
● Long service life: All high-precision resistors are used to effectively eliminate the influence of ambient temperature on the measurement results. At the same time the use of military connectors enhances the anti-vibration performance.
● Simple operation: just press the “Test” key to get the measured result. The backlight LCD displays the test result the reading is intuitive and the repeatability is good.
● Convenient to carry: It adopts portable design small size and light weight. The panel and the chassis are integrated into a structure which has good shock resistance.
