Simple Installation

MMU installation requires only three-phase voltage and current connection via low cost current transformers (CT) and voltage transformers (VT) (if needed). It is usually located at the motor control cabinet, requiring very short cable runs and avoiding the need to install equipment in remote or hazardous areas. When first switched on, MMU carries out an automatic self-learning process during which the normal operating condition of the equipment is established. Advanced analysis techniques ensure that this training takes account of variables like speed and load, and that existing faults do not result in training errors.

Ease of Maintenance Planning

Remote monitoring and reporting services contribute to the development of a sustainable predictive maintenance (PdM) system in the plant without additional workload undertaken by the crew.

Real Time Monitoring

MMU constantly takes measurements and compares them with its reference condition, in order to assess the severity and type of any developing fault. It is able to recognize abnormalities in a wide range of operating states, and is even able to extend its self-learning process when it recognizes that it has moved beyond its original learning limits. This allows MMU to achieve very sensitive detection of faults without false alarms.

Features

Ease of Use

Automated fault diagnosis feature of MMU makes it very simple to use by the maintenance personnel. Rather than overwhelming the end user with raw signals and data, MMU provides processed data results in an actionable form. The system requires minimal operator intervention for set-up and operation and provides clear indication of the nature and severity of developing faults both locally to the monitored equipment and remotely.

Highlights

Motor Monitoring Unit System (MMU)

MMU is a powerful online condition monitoring and predictive maintenance tool intended for critical AC rotating equipment. The patented machine learning algorithm of MMU enables comprehensive fault detection up to 6 months in advance. Thanks to around the clock monitoring and real-time model-based voltage and current analysis, MMU can detect electrical, mechanical as well as process faults of fixed, variable speed motors and generators.
