Overvoltage protection
Overvoltage refers to any voltage whose peak value is greater than
the corresponding peak value of the maximum steady state voltage
under normal operation. In engineering, it refers to all dangerous
voltages that can cause damage to equipment. Therefore, in the
project, some overvoltages that are larger than the normal
operating voltage of the equipment but insufficient to endanger the
normal operation of the equipment are excluded. Overvoltages
include:
(1) Transient overvoltage, with a duration of milliseconds or less,
is the main protection object of the arrester.
(2) Transient overvoltage or short-time overvoltage, the duration
is relatively long, generally between 0.1s and 1s.
