Medium and High Voltage Arrester and Lightning Standards Overviews
IEEE Standards Overviews
C62.11a -2008
IEEE Standard for Metal-Oxide Surge Arresters for AC Power Circuits (> 1 kV)
Amendment 1 Short Circuit Testing for Station, Intermediate and Distribution Arresters
In July 2008 the IEEE standards department published C62.11a, an amendment to C62.11.
This new amendment now specifies a short circuit test for all arresters. It has been years in the making.
What makes this amendment so unique is that it is virtually identical to the test procedure published in IEC 60099-4 in
2006. This is a first for arrester standards harmonization. Though it will be many years before the both standards
are virtually the same, this is a first step. See Complete Overview
C62.11 -2005
IEEE Standard for Metal-Oxide Surge Arresters for AC Power Circuits (> 1 kV)
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.
The tests 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 undesirable
surges

This standard consolidates most electric utility power industry practices, accepted theories, existing standards/guides,
definitions, and technical references as they specifically pertain to surge protection of electric power generating plants.
Where technical information is not readily available, guidance is provided to aid toward proper surge protection and to
reduce interference to communication, control, and protection circuits due to surges and other overvoltages. It has to be
recognized that this application guide approaches the subject of surge protection from a common or generalized application

IEEE 1410IEEE Guide for Improving the Lightning Performance of Electric Power Overhead Distribution Lines
This design guide is written for the distribution-line designer and contains information on methods to improve the lightning performance of overhead distribution lines. This guide recognizes that a perfect line design does not exist, and that a series of compromises are made in any distribution-line design. While some parameters such as voltage, routing, and capacity may be predetermined, other decisions are made at the discretion of the designer. The designer may exercise control over structure material and geometry, shielding (if any), amount of insulation, grounding, and placement of arresters. This guide will help the distribution-line designer optimize the line design in light of cost benefit considerations.

Railway applications - Fixed installations - DC switchgear - Part 5: Surge arresters and low-voltage limiters for specific use in d.c. systems
Clauses 4, 5 and 6 of this part of IEC 61992 cover particular requirements for surge arresters (following named arresters) for specific use in fixed installations of d.c. traction systems. These are surge arresters consisting of one or more non-linear resistors which may be in series with single or multiple spark gaps.
Low-voltage limiters are covered under Clause 7. These are protective devices mainly used in fixed installations of d.c. traction systems to connect certain portions of the circuit, when, owing to an abnormal situation, the voltage across the device exceeds a predetermined limited value. They may be associated with other devices such as contactors for self-restoring arrangements. They are not used in general to provide surge protection.
The following are the main uses of Low-Voltage Limiters (LVL):
- connection to the rail of metallic masses;
- protection of rail circuits;
- earthing of rails in the substation;
- protection of cathodic circuits;
- protection of cable shields. (Preview)
