TransformerDirect resistance test apparatus is a necessary test project of transformer manufacturing for semi-finished products and finished products, including factory test, installation, overhaul, pick up switch, pick up test and preventive test of electric power department. You can check whether the welding of the group pick upquality and the turn-to-turn short-circuit of the winding of the group, check whether the pick up touch is good at various positions of the sub-pick up switch in voltage, and whether the actual position of the sub-pick up switch is consistent with the indicating position, so as to draw out whether the line is broken, and whether the multi-strand guide line and winding are broken, etc. In order to meet the needs of full transformerdc resistance fast measurement, our company develops a transformerDirect resistance test apparatus. TransformerDirect resistance test apparatus adopts new power supply technology, featuring small volume, light weight, large current output, good repeatability, strong anti-interference ability and perfect protection function. The whole machine is controlled by high speed single chip microcomputer, with high degree of automation and automatic discharge and discharge alarm functions. Instrument test precision is high, operation is simple, and transformer direct resistance can be implemented with fast measurement.
