The RMO300GM is a portable (15 kg) stand-alone or PC-controlled digital instrument designed for the winding resistance measurement of large electrical motors and generators. It is employed for resistance measurement during the manufacturing, commissioning, and testing of:
- electrical motors and generators,
- high current bus bar joints, cable splices, and other resistive test objects
The main advantages are 300 A testing current for 10 minutes of testing and up to 200 A with unlimited testing time. The RMO300GM is equipped with three resistance-measuring channels and one channel for temperature measuring. Resistance measuring range from 0 µΩ – 999,9 mΩ, with the best resolution of 0,1 µΩ, and typical accuracy ± (0,1 % rdg + 0,1 % F.S.). With this powerful instrument, customers can easily detect problems like:
- Broken winding (open winding).
- Turn-to-turn short circuit.
- Phase-to-phase short circuit.
- Bad solder joints between the windings.
- Weakened bolted connections between windings
Th RMO300GM is the most powerful portable DC winding resistance tester for rotating machines.
DV-GM application software enables control and monitoring of the test process steps and saves and analyzes the results on a PC. It provides a test report, arranged in a selectable form as an Excel spreadsheet. The standard interface is USB while RS232 is optional.
