YY6611 oil dielectric tester is applicable for the oil dielectric test for the insulating liquids (oil) in transformers, reactors, bushings, switchgears and capacitors. The test device adopts perfect EMC design, which avoids the crash fault during test.
YR-20W type DC resistance meter is applicable to measure the DC resistance of power and distribution transformers, current transformers upto 35kV. It can also be used during temperature rise test. It is especially designed for the transformers whose resistances of HV winding and LV windings have a big difference.
YRD and YRE type transformer resistance test instrument is applicable to measure the DC resistance of power and distribution transformers, current transformers upto 240MVA. It can also be used during temperature rise test.
KRI9310 DC resistance tester is portable and automatic tester, which is applicable for the inductive test objects (such as distribution transformers, instrument transformers, reactors, etc) and the resistive test objects (such as contactors of switches, contactors of relays, wires, etc).
YT-A transformer turns ration meter is suitable for the turns ratio measurement of power transformers upto 1000kV, current transformers, voltage transformers and Z type transformers. It has L-N voltage measurement, great convenience for wiring connection, fast test speed and high accuracy.
