What is the creepage distance of a surge arrester?
Creepage distances
typically range from 25 mm/kV to 35 mm/kV of applied voltage
. While here is no agreed formula for predicting insulator power frequency flashover based on creepage, an estimate of 0.5 times the gap withstand voltage yields a conservative value. In this case, the gap is given as strike distance.

What is the duty cycle rating of a surge arrester?
The surge arrester's duty cycle rating
must exceed 125% of the maximum continuous operating voltage at its application point
. For solidly grounded systems, this voltage is the phase-to-ground voltage, while for impedance or ungrounded systems, it is the phase-to-phase voltage.
