What is the logical, step-by-step process used to find a problem in an electrical power system?

Troubleshooting is the systematic approach used to identify, diagnose, and resolve issues within an electrical power system. This method involves a series of logical steps, including defining the problem, gathering information, formulating a hypothesis about potential causes, testing these hypotheses one by one, and finally implementing the appropriate solution. This structured process ensures that the technician can effectively isolate the issue and mitigate it without causing unnecessary disruption to the system.

In contrast, preventive maintenance focuses on routine checks and servicing to prevent potential failures before they occur, rather than addressing existing problems. Relay logic refers to a method used in designing control systems, which is not specifically aimed at identifying issues. The shotgun approach, while it may involve trying out multiple solutions at once, lacks the precision and efficiency of systematic troubleshooting, often leading to confusion and additional issues rather than effectively resolving the original problem.
