What’s wrong with ElectroMechanical Metering
90 Year Old Technology
Requires Calibration
Does not respond to Harmonics

Voltage Unbalance
●Voltage unbalance causes additional negative
sequence currents to flow in induction motor.
●Resulting additional heating varies as cube of
unbalance
●
3.5% Unbalance = 25% Heating
●Conventional motor protection does not
adequately protect
●Monitoring, phase-loss protection necessary.
