Accuracy may be affected if the voltage on V1 falls below 50 V.
Potential Transformers
PTs are required for all systems with voltage levels greater than these above.
The meter inputs can be used with PTs that have secondaries rated between
50 VAC and 347 VAC +25%.
PTs should comply with IEC 61010-1, Pollution Degree 2, Overvoltage
Category III requirements.
