Electrical equipment has a design operating point. The data for this (volts, amperes, frequency) and other things such shaft output power and speed, for example, for a rotating machine help define the operating envelope.
RATED voltage is the voltage on the nameplate - the "design point" for maximum power throughput and safe thermal operation. OPERATING voltage is the actual voltage applied at the terminals to the electrical equipment.
For example - a machine has a rated ...
