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 in 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. This standard applies to devices for separate mounting and to devices supplied integrally with other equipment.
The guide does not cover motors applied in solid-state switched adjustable speed drives. Part 1 covers the insulation surge withstand strength of motors and generators with windings having form-wound multi-turn coils and the application of surge protection to form-wound multi-turn coil motors.
Grounding electrode techniques, pole ground values, and system ground grid values are not addressed or considered in this document. Systematic directions toward proper solutions of various applications are provided. In many cases, the prescribed steps are adequate. More complex and special solutions requiring study by experienced engineers is described, but specific solutions are not always given.
The procedures are based on theoretical studies, test results, and experience. Where technical information is not readily available, guidance is provided to aid toward proper surge protection and to reduce interference to communication, ied, 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 iex. Complex applications of surge protection practices may require specialized study by experienced engineers.
These considerations apply specifically to electric utility systems and do not recognize the neutral grounding requirements for dispersed storage and generation. 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 ifcamount of insulation, grounding, and placement of arresters.

It specifies the procedure for the selection of the rated withstand voltages for the phase-to-earth, phase-to-phase and longitudinal insulation of the equipment and the installations of these systems. It also gives the lists of the standard withstand voltages from which the rated withstand voltages should be selected.
This standard recommends that the selected withstand voltages should be associated with the highest voltage for equipment. This association is for insulation co-ordination purposes only. The requirements for human safety are not covered by this standard. Preview Insulation co-ordination – Part 2: Application guide This standard gives guidance for the determination of the rated withstand voltages for ranges I and II of IEC and justifies the association of these rated values with the standardized highest voltages for equipment.

Protective equipment is defined as the main circuit apparatus and ancillary equipment, which are part of a series capacitor installation, but which are external to the capacitor part itself. The recommendations for the capacitor part are given in IEC The protective equipment is mentioned in clauses 1. Surge arresters and low-voltage limiters for specific use in d. 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. They may be associated with other devices such as contactors for self-restoring arrangements. They are not used in general to provide surge protection.
