Electrical Preventive Maintenance: The Complete Guide to Protecting Your Building
When it comes to commercial buildings, electrical systems are often out of sight—but they should never be out of mind. Preventive electrical maintenance is one of the most important strategies for ensuring building safety, avoiding costly downtime, and extending the lifespan of critical infrastructure.
At Micron Group, we work with Australia’s leading facilities managers, asset owners, and property groups to deliver comprehensive electrical maintenance programs. From switchboards to lightning protection, power factor correction to emergency lighting, we offer tailored servicing across every element of your electrical system—ensuring full compliance, reliability, and long-term performance.
Why Preventive Electrical Maintenance Is Essential
Every electrical system naturally deteriorates over time. Dust builds up, terminals loosen, components wear out, and heat from resistive loads can lead to dangerous faults. Without a structured maintenance plan, these issues can result in avoidable power outages, equipment failures, fire hazards, and breaches of safety regulations like AS/NZS 3760 or AS/NZS 2293.
Proactive maintenance helps identify issues before they become critical—protecting your people, equipment, and operations. It also ensures that your building remains compliant with all statutory obligations, while reducing energy wastage and emergency callout costs.
What’s Included in Micron Group’s Preventive Maintenance Services
Switchboard Maintenance
Your main switchboard is the backbone of your electrical system. We conduct a full internal inspection of circuit breakers, terminations, busbars, insulation, and labelling. We tighten all connections, clear out dust and debris, and perform thermal imaging to detect hot spots or overloading. Where required, we coordinate planned power shutdowns with generator backup to carry out deeper maintenance safely and without disruption to your tenants.
RCD Testing and Safety Compliance
We carry out comprehensive RCD (Residual Current Device) testing in accordance with AS/NZS 3760. This includes both annual trip-time testing using calibrated instruments, and biannual manual push-button tests. Each device is logged, tagged, and recorded in your digital compliance register for audit purposes.
Appliance Test and Tag
All portable and fixed electrical appliances are visually inspected and tested for insulation resistance, earth continuity, and leakage current. We apply appropriate test tags and deliver a detailed asset register, ensuring safety in workplaces such as healthcare, education, and aged care facilities.
Thermal Imaging and Infrared Scanning
Thermal scanning is one of the most powerful tools in modern maintenance. Using high-resolution infrared cameras, we scan your electrical switchboards, control panels, and distribution systems to detect overheating, imbalanced loads, and loose connections—often before a fault even occurs.
Emergency and Exit Lighting Checks
Compliance with AS/NZS 2293 is critical for all commercial and public-access buildings. We test the functionality and battery duration of your emergency and exit lighting systems, replace failed lamps, and verify automation network integrity across platforms like DALI, Dynalite, CBUS, and Casambi.
Power Factor Correction and VAR Generator Servicing
Many commercial sites suffer from poor power factor—leading to inflated electricity bills and inefficient load handling. We inspect and maintain capacitor banks and static VAR generators (SVGs) to correct your power factor, reduce harmonic distortion, and improve energy performance. Regular testing of these systems also extends the life of your switchboards and transformers.
UPS Inspection and Battery Maintenance
Your Uninterruptible Power Supply (UPS) is essential for critical systems such as IT infrastructure, security, and emergency lighting. We inspect battery strings for voltage irregularities, test runtime capacity, and check for fan or capacitor degradation. This reduces the risk of failure during blackouts or voltage events.
HVAC Controls and VSD Maintenance
Variable speed drives (VSDs), controllers, and PLCs often go overlooked—yet they play a crucial role in HVAC efficiency and building automation. Our team inspects control loops, sensors, filters, and motor drives to ensure seamless environmental control across your facility.
Lightning Protection System Testing
Micron Group offers full inspection and verification of lightning protection systems in line with AS/NZS 1768. We conduct continuity and resistance-to-earth testing, assess air terminals and surge diverters, and verify the correct bonding of your system. This helps protect your assets and occupants during storm events.
Power Quality Logging and Analysis
We provide detailed 7–10 day logging using high-resolution power quality meters to analyse harmonics, voltage dips, spikes, flicker, and phase unbalance. This data informs energy-saving upgrades and helps diagnose hidden issues like transformer stress or equipment failure risk.
Recommended Maintenance Schedule
Our custom-built schedules are tailored to your facility but typically include:
- Annual switchboard and thermal inspections
- Biannual RCD and emergency lighting testing
- Quarterly UPS and VSD system inspections
- Annual lightning protection tests
- Routine test and tag of appliances
- Semi-annual power factor and VAR generator maintenance
- Periodic power quality logging and analysis
