Continuous Operating Voltage Factor Of Lightning Arrester

The Uc value of the B-class surge arresters should be slightly higher than the grid voltage to ensure that the B-class 11kv lightning arrester does not trigger under normal voltage conditions. For 230V AC systems, the Uc value of the B-class 15kv lightning arrester is typically 275V.
The Uc value of the C-class lightning arrester in transformer should match the operating voltage of the equipment to ensure that the C-class high voltage lightning arrester provides protection even during grid fluctuations.
