What is rated power frequency withstand voltage?

Rated frequency withstand voltage is the maximum voltage that electrical equipment or its insulation system can safely handle during normal operation at the rated frequency (such as 50Hz or 60Hz). Under this voltage, the equipment can operate normally without experiencing insulation breakdown or other failures.
