IEEE Standards Overviews
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
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

IEEE 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.
IEEE Guide for Improving the Lightning Performance of Transmission Lines
The effects of routing, structure type, insulation, shielding, and grounding on transmission lines are discussed.

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.

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;
