DC resistance tester is referred to as DC resistance measuring instrument, DC resistance meter, transformer DC resistance tester, DC resistance detector, DC digital bridge, etc. DC resistance test is an indispensable experimental item after transformer replacement, overhaul and tap changer modification. The editor of the DC high voltage generator manufacturer will introduce it in detail below.
Under normal circumstances, using traditional methods (bridge and voltage drop methods) to measure the DC resistance of transformer windings and high-power induction equipment may be a time-consuming and labor-intensive task. In order to change this situation, we have developed a high-speed DC resistance tester, which can shorten the measurement time and reduce the burden of the tester. Take high-speed microcontroller as the core.
Built-in rechargeable battery and charging circuit, using high-speed A/D converter and program-controlled current source technology, can achieve unprecedented measurement and highly automated measurement functions, high accuracy, wide measurement range, high stability, data realization, excellent repeatability Sex and interference prevention. Powerful functions and perfect protection. Features such as fast charge and discharge speed.
The instrument is small in size, light in weight and easy to carry. It has the characteristics of fast measurement, high availability and high measurement accuracy. With self-checking and active calibration functions, it reduces the difficulty of using and protecting equipment. It is an ideal equipment for measuring the DC resistance of transformer windings and high-power inductive equipment.
