TKZZ-5A DC DC resistance measurement of transformer winding resistance tester is a very important test project, I produced a TKZZ-5A Transformer DC Resistance Tester quickly in the "power equipment testing procedures", which ranked in the order of the transformer pilot project The second, "order" in the transformer provides handover, overhaul, minor repairs, change the tap position, troubleshooting and pre-test, etc., must be measured transformer winding DC resistance, and its purpose is to: ① Check the internal winding wires and welding wire quality; ② check each tap-position contact is good; ③ check whether the winding or lead at the break; ④ check the correctness of the parallel branch, if there are several parallel by winding wire wound into one or several occur ⑤ Check the floor, turn to turn short-circuit phenomenon; is disconnected. Products nickname DC resistance Tachometer, transformer DC resistance tester, transformer winding DC resistance tester, transformer direct resistance Tachometer, transformer direct resistance rapid tester, inductive load DC resistance Tachometer, inductive load DC resistance rapid tester inductive load DC resistance tester http://www.whgdmk.com/aspcms/product/2014-4-30/55.html product features a microcomputer control of intelligent instruments, test results can be stored in two large-screen backlit characters LCD display, easy operation, clear display and user-friendly human-computer interaction, measurement and instrumentation work prompted the state to fully clear 3, the DC resistance rapid tester uses a current source linear compensation technology, test stability, high accuracy, speed, improved measuring efficiency, reduce the intensity of the operator 4, technically a "four-terminal" measurements, eliminating lead and contact resistance measurement errors caused 5, panel printer can quickly print measurement results (optional) 6, overvoltage protection , to prevent the impact of counter-electromotive force 7, small size, light weight, easy to carry 8, of the DC resistance rapid tester for various types of electrical transformers, transformers and other inductive winding, measurement and analysis of low-value resistor http: // www .whgdmk.com
