• OLIP MCM STEADY, Motor Current meter

    ◆ 3-phase, AC (not suitable for DC motors), fixed speed (line driven) motors.
    ◆ Operating Temperature : 0 – 40⁰ C (32 – 104⁰ F)

    ◆ High Voltage Models (>480 Vac) : Three Cat II Voltage Transformers*: 0.5% accuracy; 100 V, 110 V, or 120 V secondary voltages

Features

MCM provides both mechanical (unbalance, misalignment, roller bearings, etc.) and electrical (loose windings, short circuits, etc.) anomaly detection as well as electrical parameters such as voltage and current imbalances and power factor. In addition, it can detect changes in the load the motor is experiencing due to anomalies in the driven equipment or process such as cavitations or plugged filters and screens. Since it doesn’t require any sensor installation on the motor itself or associated load, MCM is especially attractive for inaccessible driven equipment and is applicable to most types of pumps, compressors, and similar loads.

Description

Motor Condition Monitor for Steady Speed Motors

MCM continuously identifies existing and developing faults on electric motors and their driven equipment. MCM utilizes an intelligent, model-based approach to provide anomaly detection by measuring the current and voltage signals from the electrical supply to the motor. It is permanently mounted, generally in the motor control center and is applicable to 3-phase AC, induction or synchronous, fixed speed motors. Accompanying MCMScada Software or OLIP Enterprise Server (OPC Server) is used to view the data.
