What’s wrong with Electro-

Mechanical Metering

90 Year Old Technology

Requires Calibration

Does not respond to Harmonics

“Out of sight, Out of Mind”

No modern capabilities

No Communications

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.
