As electricians who have worked on industrial, commercial and residential projects across the Adelaide metro area for over 20 years, one of the most valuable diagnostic tools in our arsenal is thermographic inspections using infrared (IR) imaging cameras. This non-destructive testing method allows us to precisely identify potential electrical hazards and abnormalities that would otherwise be invisible to the naked eye. By capturing thermal profiles, we can detect hot spots, excessive resistance and insulation failures before they escalate into larger issues like electrical fires, equipment failures or dangerous arc flashes.
We always recommend incorporating periodic thermographic inspections as part of any preventative maintenance program for electrical systems and components. The benefits of these crucial inspections make them extremely cost-effective investments in electrical safety and asset protection. Here’s a deeper dive into the advantages IR scanning provides.
Pinpoint potential failure points
The primary function of thermography is to reveal localised heat signatures that signify high resistance connections or components at risk of imminent failure. Some common hot spots were alerted to include:
- Loose electrical terminations generating heat
- Degraded insulation allowing current leakage
- Overloaded conductors operating beyond rated temperature
- Internal faults and electrical tracking in equipment
- Imbalanced loads across phases creating heating
This advanced insight into electrical systems under full operational loads enables proactive repairs and prevention of costlier emergencies down the road from fires, faults or service interruptions.
Increased safety inspections
By highlighting potential electrical hazards in a non-destructive manner, thermographic scanning improves overall electrical safety by allowing inspections of energised, active systems without exposure risks. Areas previously deemed too hazardous for internal inspection while powered can now be evaluated externally using IR imaging.
Prioritise maintenance needs
When thermal anomalies are discovered, the data we capture helps prioritise the urgency and sequence of repairs based on temperature severity and associated fire/failure risks. Minor heat signatures may simply require monitoring, while critical exceptions are flagged for immediate action before catastrophic failure.
Protect critical power systems
Facilities that cannot afford power interruptions or costly production downtime like data centres, medical sites and manufacturing plants are well-served by routine IR scanning of electrical distribution systems. Catches loose connections and other failure points that could otherwise lead to disruptive outages impacting operations.
Third-party reporting
As independent electricians, our IR imaging scans also serve as impartial third-party condition reports for properties. We provide documented thermal evidence of electrical system status for insurance companies, building approvals and audits of preventative maintenance programs.
Upfront cost savings
While integrating an electrical thermographic inspection program does require upfront investments into IR hardware, electrician training and labour costs, the potential electrical failure and downtime avoidance pays dividends. One instance of spotted loose connection preventing an electrical fire can more than offset the total inspection costs.
From residential electrical panels to large-scale industrial control systems, there are no downsides to regularly inspecting electrical networks with infrared thermography. As an experienced electrician, these advanced scans provide x-ray operational insight that prevents failures and removes the guesswork from electrical maintenance planning.
Conclusion
If you manage or own an Adelaide property or facility with critical electrical distribution networks, we highly advise implementing IR predictive maintenance as part of your overall safety and preventative maintenance program. The upfront inspection costs are marginal compared to the potential costs of electrical fires, injuries and extended downtime from equipment failures detected too late.
