Monitoring & Metering

The MM200 includes high accuracy metering of current signals. Current parameters are available as total RMS magnitude.

Digital Counters

The MM200 provides ten digital counters to aid in system analysis. The digital counters can be used for scheduling inspections on equipment, performing qualitative analysis of system problems and spotting trends.

Learned Data

Monitoring the motor’s operating characteristics assists in determining the motor start parameters and is a critical tool for determining the operating characteristics of the system, motor and connected load.

Advanced Device Health Diagnostics

The MM200 performs comprehensive device health diagnostic tests during startup and continuously at runtime to test its own major functions and critical hardware. These diagnostic tests monitor for conditions that could impact the MM200’s performance, evaluate the criticality of this impact and present device status via SCADA communications. Providing continuous monitoring and early detection of possible issues helps improve system availability by employing predictive maintenance

HandHeld Display (HHD)

Handheld display photo

The Hand Held Display (HHD) provides a rugged local interface for MM200 Motor Protection Systems where a local display is not used in the MCC. 

The HHD provides a graphical color local interface to the MM200 Motor Protection Systems allowing local operators to view and change setting files and quickly access relay diagnostic information.

The HHD provides a clear and detailed view of all motor settings, diagnostic information and metering data available in the MM200 allowing local operators to make informed decisions on the motors operation.

Protection & Control

The 469 is a digital motor protection system designed to protect and manage medium and large motors and driven equipment. It contains a full range of selectively enabled, self contained protection and control elements as detailed in the Functional Block Diagram and Features table.

469 block diagram

Key Features

  • A, V, W, var, VA, PF, Hz, Wh, varh, demand
  • Torque, temperature (12 RTDs)
  • Event recorder
  • Oscillography & Data Logger (trending)
  • Statistical information & learned motor data
Monitoring & Metering

The 469 includes high accuracy metering and recording for all AC signals. Voltage,current, RTD and power metering are built into the relay as a standard feature.

Metering

The following system values are accurately metered and displayed: Phase, differential and ground currents, average current, motor load, current unbalance. Phase-to-ground and Phase-to-phase voltages, average phase voltage, system frequency. Real, reactive, apparent power, power factor, watthours, varhours, torque Current and power demand. Analog inputs and RTD temperatures. Thermal capacity used, lockout times, motor speed

Monitoring

The 469 is equipped with monitoring tools to capture data. The following information is presented in a suitable format.

Event Recorder

The event recorder stores motor and system information with a date and time stamp each time a system event occurs. Up to 256 events are recorded.

Oscillography

The 469 records up to 128 cycles with 12 samples per cycle of waveform data for 10 waveforms (Ia, Ib, Ic, Ig, Diffa, Diffb, Diffc, Va, Vb, Vc) each time a trip occurs. The record is date and time stamped.

Advanced Motor Diagnostics

The Multilin 469 provides advanced motor diagnostics including a broken rotor bar detection function. The broken rotor bar detection is a condition maintenance function that continuously monitors the motor’s health while in operation. The advanced Motor Current Signature Analysis (MCSA) continuously analyzes the motor current signature and based on preset algorithms will determine when a broken rotor bar is present in the motor.
