Preventive Maintenance
Preventive Maintenance is essential for ensuring the continuous and safe operation of electrical systems and equipment. It involves scheduled inspections, testing, and servicing activities to identify potential failures before they occur, thereby reducing unplanned downtime and costly repairs.

- Insulation resistance testing for cables, motors, and transformers
- Continuity and polarity checks
- Loop checking of control circuits
- Primary and secondary injection testing of protection relays
- Functional testing of switchgear, breakers, and control panels
- Verification of grounding systems and earthing continuity
- Voltage withstand (HiPot) testing for high-voltage equipment
- Transformer ratio, vector group, and winding resistance testing
- Testing of CTs and PTs for accuracy and polarity
- Relay logic and interlock verification
