Answer: A robust electrical preventive maintenance (EPM) plan is crucial for ensuring the safety, reliability, and longevity of industrial power systems. Key practices include:

• Routine Inspections and Testing: Conduct periodic visual inspections of all electrical equipment, including overhead transmission lines, underground cables, transformers, and switchgear. Use specialized tools for tests like insulation resistance, thermography (infrared scanning), and oil analysis to detect potential issues before they cause a failure.

• Vegetation Management: For overhead lines, a critical part of maintenance is managing vegetation to prevent tree contact, which is a major cause of power outages.

• Cleaning and Corrosion Control: Regularly clean insulators and equipment to remove contaminants. Apply anti-corrosion coatings to exposed metal components to prevent rust and deterioration.

• Documentation and Record-Keeping: Maintain detailed records of all maintenance activities, test results, and equipment performance. This data helps in tracking trends, forecasting potential failures, and ensuring compliance with industry standards.

• Safety Protocols: Always follow strict safety protocols, including using appropriate personal protective equipment (PPE), to ensure the well-being of maintenance personnel.
