2024年9月9日 · Our 30-hour Electrical Power System training course is actually three separate courses: Power System Fundamentals, Short Circuit Analysis & Protective Device Coordination, and Arc Flash Analysis/Study.
the performance indicator for the motor. A means of analysing the impact to the motor when variations in the motors performance characteristics are changed is provided. Practical examples of the more common motor failures will be discussed, explaining the failure mechanism and the means to prevent or reduce simi-lar failures.
