Monitoring and 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. • Status of inputs, outputs and alarms • Last trip data • Motor learned parameters: last and maximum acceleration times, starting currents and starting TCU, average currents, RTD maximums, analog inputs maximums and minimums. • Trip and general counters, motor running hours and start timers. • Event recorder • Oscillography
