IEEE Std C37.12.1-2018 pdf download – IEEE Recommended Practice for Instruction Manual Content of AC High- Voltage Circuit Breakers above 1000 V.
4.6 Circuit breaker field testing instructions The specific field tests that are to be performed on the circuit breaker during installation or maintenance testing and pass/fail criteria should be described. Identify areas of the instruction manual or test reports where comparative factory test results can be located. Describe any special features and conditions that are essential for proper field testing. 4.7 Circuit breaker operating instructions The instructions for operating the circuit breaker including operation during maintenance activities should be included. llustrations for complex procedures and use of special tools should be included. 4.8 Description of circuit breaker auxiliary systems (pneumatic or hydraulic systems, SFe systems, etc.) The basic principles ofhow the circuit breaker’s auxiliary systems operate, and any special features, conditions, and precautions that are essential for its operation should be provided. 4.9 Description of circuit breaker mechanism The basic principles of how the circuit breaker mechanism operates and any special features and conditions that are essential for its operation should be provided. This clause (or another clause on auxiliary items) should identify, by manufacturer and model number, all accessories such as pressure or density indicators/switches, oil level indicator/switches, etc. 4.10 Description of circuit breaker interrupter The basic principles of how the circuit breaker interrupter operates, and any special features, conditions, and precautions that are essential for its operation should be described.
4.13 Failure reporting It is important for the resolution of problems discovered during operation of the circuit breaker that the user informs the manufacturer of the details of any such problems. To aid in this process, the instruction manual should identify the use ofIEEE Std C37.10 as well as the manufacturer’s resources for this process. 4.14 End-of-life procedures Preparation for disposal of the circuit breaker should be described. This description may include the process for discharging the stored energy and pressures contained in the operating mechanism and interrupters. Include information to remove hazards safely. NOTE- Requirements for safely handling and disposing of materials in accordance with environmental codes and laws vary by jurisdiction and are subject to change. Therefore, the instruction manual may not cover all requirements for every installation. The user should verify compliance with the requirements for the specific installation.
