From Scheduled Inspections to Continuous Monitoring: Rethinking Critical Asset Maintenance
September 9, 2026Maintenance teams responsible for transformers and substation assets face a common problem: some of the most critical equipment on site is also the most difficult to inspect under normal operating conditions. Access restrictions, energised equipment and site safety requirements can limit how often detailed inspections are performed.
For utilities, DNSPs and industrial operators managing geographically dispersed assets, the challenge is maintaining awareness of equipment condition between inspection intervals without increasing the number of site visits required. Balancing maintenance budgets, workforce availability and the long-term management of ageing infrastructure continues to place pressure on maintenance programs across Australia.
Online condition monitoring technologies are helping address this challenge by providing access to asset data between inspections, enabling maintenance teams to identify developing issues sooner and support more effective condition-based maintenance strategies.
The Limits of Periodic Inspections
Routine inspections remain an important part of asset management, providing valuable information about equipment condition and performance.
However, inspections only capture what is happening at a particular moment in time. For DNSPs and other operators managing assets across large geographic networks, increasing inspection frequency is not always practical. Site access requirements, travel costs and the availability of specialist personnel can all place constraints on maintenance programs.
As a result, many organisations are looking to complement traditional maintenance programs with technologies that can provide ongoing oversight between scheduled inspections.
Supporting Condition-Based Maintenance
Condition-based maintenance relies on understanding how equipment is performing in service and directing resources where they are needed most.
Rather than relying solely on fixed maintenance intervals, asset owners can use operational data to identify emerging issues, prioritise maintenance activities and make more informed decisions about critical infrastructure.
The ability to collect and interpret that data consistently is becoming increasingly important as Australian utilities and industrial operators continue to manage ageing infrastructure, accommodate growing demand and extend the operational life of critical assets.
Turning Asset Data into Actionable Information
The Systems With Intelligence™ (SWI) Industrial IoT Monitoring Platform provides a centralised environment for monitoring and managing data from critical assets.
The platform can integrate thermal and visual inspection technologies alongside third-party sensors, bringing information from multiple sources into a single interface. Automatic alerts can be configured to notify operators when equipment exceeds predefined thresholds, helping maintenance teams investigate potential issues sooner.
Benefits include:
- Monitoring of remote and difficult-to-access sites
- Earlier identification of developing asset issues
- Reduced reliance on routine site attendance
- Support for condition-based maintenance strategies
- Improved management of ageing infrastructure
- Reduced exposure to high-risk inspection activities
Enabling Touchless Inspections
Transformer inspections highlight where continuous monitoring can deliver significant operational value.
Across utility networks, substations and industrial facilities, inspecting enclosed transformer connections may require planned outages, specialist personnel and physical access to energised assets. These requirements can make frequent inspections both costly and disruptive, particularly across regional and remote locations where mobilising personnel may require significant time and resources.
The IM500 Industrial IoT module helps overcome these challenges through integrated thermal and visual monitoring. Installed directly at the asset, the device captures operational data from live equipment and transmits it securely to the SWI monitoring platform.
This enables maintenance personnel to review temperature trends, visual imagery and alarm conditions remotely, reducing the need for routine physical inspections while maintaining oversight of critical equipment.
Combined with the SWI platform, the solution provides a practical approach to touchless inspections, helping organisations monitor assets that would otherwise be difficult, costly or time-consuming to inspect on a regular basis.
A More Informed Approach to Asset Management
Remote monitoring is not intended to replace inspections altogether. Instead, it provides an additional source of information that can help maintenance teams better understand asset condition between scheduled site visits.
When integrated with existing SCADA, GIS and enterprise asset management systems, monitoring data can contribute to a broader asset management strategy, supporting more effective planning and the ongoing management of critical infrastructure.
As utilities and industrial operators continue to seek safer and more efficient ways to maintain essential assets, continuous monitoring is playing an increasingly important role in how those assets are managed.
