Thermal Imaging Sydney for Switchboards & Electrical Fault Detection
AGE Electrical Testing Services provides electrical thermal imaging in Sydney for commercial buildings, strata sites, warehouses, healthcare facilities and industrial switchboards. Our Category 2 or higher thermographers use thermal scanning (infrared scanning) on live switchboards to look for abnormal heat. Those patterns can indicate a loose connection, an overloaded circuit, phase imbalance or a component that needs checking, before an outage or a fire risk develops.

Thermal Imaging Quotes for Sydney Sites
Thermal imaging pricing depends on the size and layout of the site, the number of switchboards or distribution boards, access requirements, reporting detail and whether the inspection is for maintenance, insurance or compliance purposes.
For small commercial sites, a single main switchboard may be enough. Larger buildings, warehouses, strata sites, healthcare facilities and multi-site portfolios often require multiple scans across main switchboards, distribution boards, mechanical services boards and plant areas.
To provide an accurate quote, we usually need:
- site address
- number of switchboards or electrical boards
- whether access is during or after business hours
- whether the report is required for insurance, maintenance or compliance
- any known electrical issues or previous thermal imaging findings
Once we have those details, we can provide a clear fixed quote before attending site.

Why thermal imaging in Sydney?
AGE Electrical Testing Services provides electrical safety and compliance services for commercial, industrial, strata and healthcare sites across Sydney. Our thermal imaging inspections are carried out by experienced electrical professionals and are focused on identifying switchboard issues before they lead to outages, equipment damage or fire risk.
This is electrical switchboard thermography — infrared inspections of main switchboards, distribution boards, electrical panels and plant rooms — not building leak detection, roof scans, pest inspections or medical thermography.
From CBD towers to Western Sydney warehouses and healthcare sites, electrical systems run hard. Loose lugs, high-resistance joints and overloaded phases often heat up long before a breaker trips. Infrared scanning of live switchboards under normal load shows those patterns early so maintenance can plan repairs instead of reacting to an outage.
For the national method and reporting standard, see electrical thermal imaging. Also see test and tag and RCD testing.
What Your Thermal Imaging Report Includes
After the inspection, AGE Electrical Testing Services provides a clear electrical thermal imaging report to help facilities managers, strata managers, maintenance teams and contractors understand what was found and what action is required.
The report is designed to make switchboard issues easy to identify, prioritise and repair. It can also provide useful supporting evidence for maintenance planning, insurance records, compliance reviews and contractor follow-up — practical documentation for commercial, strata, industrial, warehouse and healthcare sites.
Reports may include:
- thermal images showing abnormal heat patterns
- visual images of the switchboard, panel or component where required
- switchboard or distribution board name and location
- component, circuit or phase affected
- measured hotspot temperature
- reference temperature
- Delta T temperature difference
- likely cause of the issue
- defect priority rating
- recommended corrective action
- notes for follow-up or reinspection where required
The aim is to give the site team practical information they can act on, not just a folder of thermal images. A strong switchboard thermal imaging report helps prioritise defects before outages or equipment failure, and supports contractors carrying out repairs.
What is Delta T?
Delta T is the temperature difference between the suspected hotspot and a comparable reference point. In electrical thermal imaging, Delta T helps show how severe a defect may be and whether it should be monitored, repaired soon or treated as a higher priority issue.
This helps facilities managers and maintenance contractors prioritise repairs based on risk, rather than guessing from a thermal image alone.

Real-World Thermal Imaging Findings
AGE Electrical Testing Services conducts switchboard thermal imaging across commercial, industrial and facilities-managed sites. Our inspections combine infrared thermography with electrical knowledge, temperature comparison, Delta T analysis and defect priority classifications.
The examples below demonstrate genuine electrical anomalies identified during AGE thermal imaging inspections and how the findings were translated into practical maintenance recommendations. Client and site identities are withheld.
Localised Heating on a Three-Phase A/C Circuit
During a switchboard thermal imaging inspection, localised heating was identified at the lower termination of a three-phase air-conditioning circuit.
The affected point reached a maximum temperature of 52.1°C, compared with a reference temperature of 25.2°C (adjacent phases approximately 25–26°C), producing a Delta T of approximately 27°C.
The remaining phase temperatures were comparatively balanced. This helped distinguish the localised anomaly from the general heating that might normally be expected when a three-phase air-conditioning circuit is operating under load.
The finding was classified as Priority 2, allowing the maintenance team to investigate and rectify the connection before further deterioration could contribute to equipment damage or an unplanned outage.
Severe Overheating of a Mechanical Services Time Switch
A separate thermal imaging inspection identified severe localised overheating on a Hager EHN011 24-hour time switch within a mechanical services distribution board.
The component reached a maximum surface temperature of 113.2°C, compared with a reference temperature of 37.9°C, resulting in a Delta T of 75.3°C.
The location and severity of the thermal anomaly indicated a possible high-resistance connection, deteriorating internal contact or component failure.
The defect was classified as Priority 1 – Immediate Action Required, with urgent electrical investigation recommended.
Recommended actions included checking circuit loading and wiring configuration, inspecting and re-terminating associated connections, and replacing the time switch where evidence of overheating, loose terminations or internal damage was identified.
From Thermal Image to Actionable Report
Identifying a hotspot is only part of an effective electrical thermography inspection.
AGE thermal imaging reports combine infrared findings with electrical context so facilities and maintenance teams can understand where the anomaly is located, how significant the temperature difference is, what may be causing it and what action should be considered.
Depending on the finding, reports can include:
- thermal and corresponding visual images
- maximum fault temperature
- reference temperature
- Delta T analysis
- component and switchboard identification
- fault observations
- defect priority classification
- recommended corrective actions
This provides a documented record for preventative maintenance, contractor follow-up, asset management and insurance or risk-management purposes.

What should a site check before using a thermal report for insurance?
Reports can include thermal images, temperature data, Delta T where it is relevant, a priority rating and a recommended action. Insurers set their own requirements, so check anything specific with the insurer or broker. A report is a maintenance record, not a promise that a policy condition is met.
Can you perform thermal imaging on live switchboards in high‑rise buildings?
What does an electrical thermal imaging report include?
An electrical thermal imaging report may include thermal images, visual images, switchboard locations, component details, measured temperatures, reference temperatures, Delta T analysis, defect priority ratings and recommended corrective actions.
Can thermal imaging reports be used for insurance records?
Thermal imaging reports are commonly used as supporting evidence for electrical maintenance, risk management and insurance records. Requirements can vary between insurers, so site managers should confirm any specific reporting requirements with their insurer or broker.
What is Delta T in thermal imaging?
Delta T is the temperature difference between a hotspot and a comparable reference point. In switchboard thermal imaging, it helps assess how severe an overheating component may be and whether it should be monitored, repaired or treated as a higher priority issue.
