This application guide covers procedures and calculations necessary to apply the standard transient recovery voltage (TRV) ratings for ac high-voltage circuit breakers with rated maximum voltage above 1000 V. The breaking capability limits of these circuit breakers are determined to a great degree by the TRV. This application guide is not included in other existing circuit breaker standards. In this document, the TRV ratings are compared with typical system TRV duties. Examples of TRV… read more calculation are given with suggested options if the TRV duty exceeds the TRV ratings of the circuit breaker. read less

The guide reviews existing standards and performance criteria for switchgear rated above 1000 V. Each aspect of performance is discussed within the context of sulfur hexafluoride alternatives, how their behavior may differ from existing technologies, and how this behavior may lead to changes in the qualification process. Relevant analytical, numerical, and test methods are discussed which may contribute to the process of performance evaluation and evolution of the standards.

This standard provides a procedure that shall be used to (1) assess structures for atmospheric corrosion; (2) assess the level of risk to the structure in terms of corrosion attack and degradation to the existing coating system; (3) make informed decisions based on those findings as to whether coating repair is needed, and if so, to what extent; and (4) apply repair coatings to the structure if applicable. This standard applies to the repair of above-grade atmospheric coatings. For the purposes… read more of this standard, the atmospheric area to be coated generally comprises of that portion of the utility support structure above the transition zone, which is that portion of the coating exposed up to 600 mm (24 in) above grade. read less
