Brief introduction
DC resistance measurement of transformer winding is an essential test project during transformer delivery, repair and changing tapping switch. You can check the inter- welding quality and whether the winding with short circuit , can detect voltage divider tap each position is good and the actual position of the tap changer position is consistent with the instructions , lead breaks, multi-strand wire there broken stocks and so on. The instrument uses a new power technology, small in size, light weight, high output current, repetitive good, strong anti-jamming capability, and the perfect protection function and so on. The machine is controlled by a high-speed single-chip, high degree of automation, with automatic discharge and discharge alarm function, high precision, easy to operate, enabling rapid measurement of transformer DC resistance.
Products features
