 Phase-phase voltage of the Plant Main AVR (Automatic Voltage Regulator)
output
- Measure the phase-phase voltages. (Mandatory check
item) Tolerance of voltage between phases should be
±5%.
e.g.) Main power AC200V : Spec. AC190V ~ AC210V
- Measure the voltage between each phase (R,S,T) and
F.G.
Tolerance of voltage between phases should be ±5%.
e.g.) Main power AC200V: Spec. AC95V ~ AC105V
 Machine input voltage 
Phase-phase voltage of
machine input
- Measure the phase-phase voltages. (Mandatory check
item) Tolerance of phase-phase voltage should be ±5%.
e.g.) Main power AC200V: Spec. AC190V ~ AC210V
- Measure the phase (R,S,T) - F.G voltages.
Tolerance of phase-F.G voltage should be ±5%.
e.g.) Main power AC200V: Spec. AC95V ~ AC105V
