How do you approach identifying and resolving power quality issues in an industrial facility?

Sample interview questions: How do you approach identifying and resolving power quality issues in an industrial facility?

Sample answer:

1. Gather and Analyze Data:

   • Collect information on electrical system configuration, load profiles, and historic power quality data.
   • Analyze data to identify patterns, trends, and potential sources of power quality issues.

2. Conduct Site Inspection:

   • Perform a thorough visual inspection of the electrical system, including distribution equipment, transformers, panels, and wiring.
   • Check for loose connections, damaged components, and proper grounding.

3. Evaluate Power Quality Parameters:

   • Measure and monitor power quality parameters such as voltage sags, swells, flicker, harmonics, and power factor.
   • Compare measured values against industry standards and manufacturer recommendations.

4. Identify Potential Causes:

   • Analyze power quality data and inspection findings to identify potential causes of issues.
   • Consider factors such as load imbalances, harmonic-generating equipment, and poor grounding.

5. Recommend Solutions:

   • Develop a plan to address the identified issues.
   • Suggest solutions like installing harmonic filters, power factor correction devices, or upgrading aging equipment.

6. Implement and Test Solutions:

   • Implement the recommended solutions and conduct thorough testing to verify their effectiveness.
   • Adjust the solutions as needed to achieve optimal power quality.

7. Continuous Monitoring:
