RMM
Features & Benefits
• The RMM's design allows for independent operation (without a connected PC) yet features a wide variety of built-in communication abilities.
Design Advantages
No other partial discharge monitor in the market has all the features and functions of the Dynamic Ratings RMM. The RMM features a minimum of fifteen independent (concurrently monitored), highly sensitive, user configurable input channels; delivering the industry’s best signal-to-noise ratio and allowing connection to any brand of PD sensor!
The RMM is more than just a Partial Discharge (PD) monitor. Inputs are available for six RTD winding temperatures, three load currents, three voltages and six user defined (4 - 20 mA) inputs. The RMM has the capability to perform motor current signature analysis for the detection of broken rotor bars in induction machines. The RMM will store up to two years of data using a first-in, first-out (FIFO) method.
