DC winding resistance testing is regarded as another essential routine screening tool. It indicates problems such as loose, defective or incorrect connections, which cause enough transformer failures each year to be regarded as a failure category of its own. Winding resistance tests may also reveal problems with a transformer’s tap changer (s), on-load (OLTC) and/ or de-energized (DETC) – a major and, by some statistics – leading, component category that fails in transformers.

JYR-10C/05C use new power supply technology which will prolong working life of the instrument and reduce damage rate greatly, the tester with DC and AC switch which will be suitable for all inductive load measurements such as transformer, PT, CT, etc.


● With inner set high efficiency power source, no fan can avoid the dusts coming in which can increased the life time.

● The measuring range is 0100kΩ

● The Max. output voltage is 24V, the testing speed is high.

● The instrument has permanent calendar, 100 sets of data can be stored, temperature automatic converting function, the data will not be loosen as power failure and convenient for looking up.

With large color touch screen, the data is clear and easy to read.

With thermal printer for printing.

With RS485 communication interface for PC control.

With U disk storage interface for exporting datas.

● With the anti-arcing protection function for the inductive tested products.

● With AC380V misconnection protection function to avoid the damage by incorrect operation.

● With the discharging alarm by sound and the discharging indicating clearly.

JYR-10C Power transformer winding resistance tester is a professional testing equipment which is suitable for transformer service industry, substation maintenance, power transformer rewinding service, power transformer /distribution transformer maintenance company, 3 phase transformer testing, and other transformer testing field, Kingrun series winding resistance tester such as JYR-10C, JYR-20W,JYR-50C, JYR-9310 and JYR-20S testers which have reliable capability and accurate testing result selected by SIEMENS and ABB transformer manufacture and transformer service companies.

High performance of MPU (microprocessor) can provide high precise data and fast calculation:
