Winding Ohmmeter

About Winding Ohmmeter

 

Simple and quick reliable DC resistance measurement is a basic maintenance task performed on electrical motors and generators. Resistance measurement can help maintenance personnel to detect different problems regarding winding in electrical rotating machinery, such as turn-to-turn short circuit, phase-to-phase short circuit, short-to-ground short circuit and etc.

Three channels, four-point Kelvin measurement of resistance, enable users of RMO-M devices to obtain a simultaneous measurement of up to three windings in rotating machinery. This cuts down testing time significantly.

Various problems can be detected with RMO-M instruments:

  • Broken winding (open winding)
  • Turn-to-turn short
  • Short-circuited winding
  • Phase-to-phase short
  • Low quality of solder joints
