IEEE C62.11:1999

Revision Standard - Superseded.
Superseded by IEEE Std C62.11-2005 Metal-oxide surge arresters designed to repeatedly limit the voltage surges on 48¬62 Hzpower circuits (>1 kV) are covered in this standard. These devices operate by discharging surgecurrent. Devices for separate mounting and those supplied integrally with other equipment are alsodiscussed.

This standard applies to metal-oxide surge arresters (MOSA) designed to repeatedly limit the voltage surges on 48–62 Hz power circuits (> 1 kV) by passing surge discharge current and automatically limiting the flow of system power current. This standard applies to devices for separate mounting and to those supplied integrally with other equipment.
