IEEE Std C37.12.1:2018 pdf download.IEEE Recommended Practice for Instruction Manual Content of AC High-Voltage Circuit Breakers above 1 000 V.
This recommended practice is intended to identify, organize and summarize information about high-voltage circuit breakers provided by the manufacturer that knowledgeable users will find useful for the receipt, installation, commissioning, operation and maintenance, and decommissioning of ac high-voltage circuit breakers above 1000 V. This recommended practice recommends categories and an arrangement for the presentation of information in circuit breaker instruction manuals.
1.2 Purpose
The purpose of the document is to provide recommendations for authors and those who specify instruction manuals fbr ac high-voltage circuit breakers. Structuring instruction manual content according to a common (standard) format shown herein will allow knowledgeable users a means to effectively and quickly, find the information they need:
— To receive, install, and commission new high-voltage circuit breakers.
— To operate, inspect, maintain, and repair high-voltage circuit breakers throughout their service life.
— To decommission the high-voltage circuit breakers at the end of their service life.
1.3 Limitations
This recommended practice addresses various forms of documentation that pertain to high-voltage circuit breakers. IEEE Std C37.04 requires essential markings on a circuit breaker whereas this recommended practice is directed at the various forms of documentation that pertain to a circuit breaker.
Users are advised that this recommended practice is NOT an instruction manual.
This recommended practice suggests items for inclusion in an instruction manual that is to be prepared by the circuit breaker manufacturer. A manufacturer may include additional information that is not identified in this recommended practice. Users are to follow manufacturer’s instructions in the care of circuit breakers.
Clause 5 contains additional requirements for high-voltage circuit breakers. Some items do not apply to a specific technology of circuit breaker. Circuit breakers used in metal-clad or metal-enclosed switchgear assemblies, or supplied in gas-insulated switchgear, may be supplied with a generic instruction manual with applicable data tabulated for user reference.
