IEEE C62.11 2012 Edition, October 19, 2012 Metal-Oxide Surge Arresters for AC Power Circuits (>1 kV)
More info
Description / Abstract:
This standard applies to metal-oxide surge arresters (MOSAs)
designed to repeatedly limit the voltage surges on 48 Hz to 62 Hz
power circuits ( 1000 V) by passing surge discharge current and
automatically limiting the flow of system power current. This
standard applies to devices for separate mounting and to devices
supplied integrally with other equipment.
Purpose
To define tests that demonstrate that an arrester can survive the rigors of reasonable environmental conditions and system phenomena while protecting equipment and/or the system from damaging overvoltages caused by lightning, switching, and other system disturbances.
