Routine maintenance
Routine maintenance refers to day-to-day, minor tasks performed on electrical equipment to ensure consistent operational reliability. Minor repairs, such as tightening loose connections, cleaning terminals, or replacing minor gaskets, are performed during these scheduled intervals to prevent minor issues from escalating into major faults.

MTBF=Number┬аof┬аFailuresTotal┬аUptimeтАЛ тАФ Mean Time Between Failures metric, improved by routine maintenance.
R(t)=eтИТ╬╗t тАФ Reliability function where routine maintenance minimizes failure rate ╬╗.
The principle relies on the 'Time-Based Maintenance' strategy, where inspections are conducted at fixed intervals regardless of equipment condition. By performing small repairs during these visits, technicians address signs of wear and tear, vibration effects, or environmental accumulation before they impact the system's overall performance or safety.
Routine maintenance is predictive and schedule-oriented.
It covers tasks like inspection, lubrication, cleaning, and minor tightening.
Essential for extending the life of transformers and switchgear.
Distinguishes from breakdown maintenance which is reactive and costly.
Reduces unexpected system downtime.
Ensures safety and regulatory compliance.
Cost-effective compared to major overhauls.
Requires scheduled outages.
Possible unnecessary maintenance if the equipment is in perfect health.
Transformer bushings inspection.
Circuit breaker contact cleaning.
Oil level verification and top-up.
Relay logic testing.

Breakdown maintenance (Option B) involves repair only after a failure occurs, often resulting in high emergency costs.
Preventive maintenance (Option D) is a broader category often including routine tasks but can also include planned replacements based on degradation data.
C is correct тАФ Routine maintenance is specifically designed for regular, minor adjustments and repairs to prevent equipment deterioration.
Always remember: Routine maintenance is for 'minor' issues, while 'Breakdown' is for 'total failure' and 'Preventive' is for 'scheduled replacement' based on age or condition.
