Josh,
A kWh meter is a pretty simple sort of a thing, using only a Current (Series) coil and a Voltage (Parallel) coil to excite an Aluminium disc, in the crude form of a motor.
The only real thing that will cause an upset is a shorted winding or two, in the Voltage coil.
It can happen, but very rarely.
