Inspection and Maintenance

Inspection and maintenance

Whether you need a rapid response or a long-term program, Mondo can inspect, assess, monitor and protect your assets from the ground up.

With decades of experience under our belts, our solutions are streamlined, cost-effective and timely. For you—and your customers—that means a safe, reliable network both now and in the future.


Comprehensive inspection solutions for all elements of your electricity network.

Choose us for either rapid response or routine programmes to inspect and report on the condition of your network assets, using both aerial and ground based inspections.

Mondo can inspect your network quickly and safely in a wide range of environments with its fleet of aerial and ground-based methods.

Aerial Inspection

If you need a bird’s eye view of your assets, we’ve got it covered. We provide manned and unmanned aerial inspection platforms including helicopters, fixed-wing UAVs and propeller drones.

Our unmanned craft are ideal for inspecting conductors, cross arms, towers and easements in semi-urban environments.

Our fleet of helicopters are perfect for inspection of vast networks and make it possible to inspect hundreds of poles in a single day, uncovering defects and failures which would not be observable from the ground.

Mobile workforce management

Mondo’s mobile workforce management system, FMC, will help you manage maintenance crews more efficiently and effectively than ever before.

You can plan, allocate, review and modify work allocation in real time. Workers can enter data in the field, improving accuracy and reporting. FMC is also device agnostic which minimises the cost of rolling it out.

Productivity and accuracy, up. Costs and confusion, down.

Metering solutions for networks

Mondo tailors metering solutions for electricity authorities, energy retailers, consultants and large commercial and industrial customers.

As well as installation, maintenance and testing we are experienced in mass replacement programs and outage services. We can provide a complete planning, sourcing, installation, maintenance and audit service, or we can design a sub-metering and energy monitoring system for a specific requirement.

Our solutions are robust and can be scaled to any requirement. Above all they are designed to help you extract valuable information from your network so that you can be more efficient and find new sources of value for your customers.

Condition monitoring

Mondo offers diagnostic testing and condition monitoring of transformers, cables, switchgear and materials both in the field and in our laboratory.

Transformers, generators, motors and switchgears

Our engineers can identify manufacturing and design defects, internal deficiencies, damage from transportation and on-site assembly in transformers or carry out non-invasive testing of electrical plant.


Mondo is accredited by NATA to calibrate test equipment and instruments both in our lab and on site. We can also carry out earthgrid testing, impulse testing to 160 kV and testing of transformers.

Chemical analysis

Mondo’s laboratory offers a range of services in oil and gas chemical analysis for diagnostic testing and condition monitoring programmes. Our analyses include dissolved gas analysis, oil colour and appearance, water content and acidity, interfacial tension, sediment and sludge, and particle profiles.

Cable testing

Mondo conducts a range of tests on power cables and underground cable systems to identify faults, assess condition and for field commissioning. Our testing services include very low frequency testing, oscillating wave test system, frequency domain spectroscopy, time domain reflectometry, partial discharge testing and high voltage AC testing.
