High Voltage Electrician Interview Questions
What steps do you take to troubleshoot and identify faults in high voltage electrical systems?

Sample answer to the question

When troubleshooting and identifying faults in high voltage electrical systems, I follow a systematic approach. First, I gather information about the issue by interviewing the operator or reviewing maintenance records. Then, I conduct visual inspections to check for any obvious signs of damage or malfunction. If necessary, I use diagnostic tools and equipment to measure voltage, current, and resistance to pinpoint the fault. I also refer to electrical schematics and drawings to understand the system's layout and components. Once the fault is identified, I develop a plan to repair or replace the faulty component. Throughout the process, I prioritize safety by following electrical safety standards and regulations.
