For building electrical maintenance, the right strategy and tools make all the difference. A proactive approach is far superior to simply fixing things as they break, especially given the high stakes of electrical system failure.
Comparing Maintenance Strategies
Different maintenance approaches offer various levels of protection and efficiency.
Run-to-Failure (Reactive Maintenance): This “break-fix” model seems cheap initially but leads to emergency repairs, unplanned downtime, and serious safety hazards.
Preventive Maintenance: This common-sense approach involves scheduled inspections and tasks based on time intervals. It significantly reduces breakdowns but can sometimes result in unnecessary maintenance or miss developing issues.
Predictive Maintenance: This advanced strategy uses real-time data from sensors and thermal imaging to predict when maintenance is actually needed, optimizing schedules and preventing failures before they occur.
Reliability-Centered Maintenance (RCM): This gold-standard, risk-based approach focuses maintenance on the most critical components, maximizing reliability while minimizing costs. It requires significant upfront planning but delivers the best results.
Highest long-term cost; unplanned downtime; safety hazards; equipment damage; emergency repairs; no operational continuity; obviously not ideal.
Preventive Maintenance (PM)
Time/Usage-Based
Reduces breakdowns; extends asset life; improves safety; planned downtime; much smarter than waiting for something to break.
Can be inefficient (maintenance performed too early); doesn’t predict actual failure; might miss issues between scheduled checks.
Predictive Maintenance (PdM)
Condition-Based (data)
Optimizes maintenance schedule; reduces downtime; extends asset life; higher efficiency; detects issues before they become problems; leverages real-time data.
Requires specialized tools/sensors; higher initial investment; data analysis expertise needed.
Reliability-Centered Maintenance (RCM)
Risk-Based
Most effective; maximizes reliability; reduces risk; improves safety; lowers repair costs; focuses on critical assets.
Complex to implement; requires significant data and expertise; resource-heavy.
