Rotating Machine (Motor & Generator) Diagnostic Monitor, RMM
The RMM (Rotating Machine Monitor) is a microprocessor-based device that continuously monitors the insulation system for partial discharges as well as other parameters such as power, thermal and mechanical condition of a medium voltage motor, turbine generator or Hydro generator.
The basic standalone unit shown in the picture consists of three modules (from the left to the right):
- Power Supply
- Main CPU module
- A 15-channel partial discharge module
The basic unit may be extended with additional modules allowing for more economical or accurate way of monitoring multiple objects.
The basic unit may be extended with additional modules allowing for more economical or accurate way of monitoring multiple objects. RMM can have up to six PD modules allowing monitoring up to six motors (within allowable signal cable distance) with one monitor.
A separate vibration module may be installed and used in conjunction with the four vibration signal channels already located on the main CPU module. This will allow for remote vibration monitoring of the machine and the load if other vibration monitoring equipment is not installed.
