One test set, two wins — Why MTOU3 works for crews and maintenance managers

Crews want tools that are fast, safe, and consistent. Maintenance managers want reliability, ROI, and fewer repeat site visits.

Crews want tools that are fast, safe, and consistent. Maintenance managers want reliability, ROI, and fewer repeat site visits. But most test sets force a trade-off. The MTOU3 changes that — giving both teams what they need, without compromise.

The field perspective: Built for real crews

Technicians don’t want complexity — they want results. The MTOU3 is designed to remove the barriers that slow field work down:

  • One connection for all windings = fewer climbs and less risk
  • Confirm vector prevents setup errors before they become retests
  • Automatic sequencing means faster, smoother test routines
  • Shared interface with the TAU3 reduces training time across crews

The result? Crews spend more time testing and less time troubleshooting or climbing again to fix a missed connection.

The operational perspective: Results that protect time, budget, and reputation

Operations managers don’t just need accurate results — they need results they can rely on without chasing teams for retests or clarifications.

The MTOU3 helps standardise winding resistance testing across crews and regions, reducing variability and improving reporting confidence. Fewer retests and repeat visits mean tighter schedules and fewer disruptions to commissioning or planned maintenance.

It’s also easy to train and deploy — so teams can scale quickly without relying on a handful of experienced testers. And because safety is built into every step, there’s less exposure, less risk, and fewer surprises.

“The ROI isn’t in the features — it’s in the time saved, the trust in the result, and the ability to repeat it site after site.”

The ROI of getting resistance testing right

Winding resistance testing often gets treated as routine — but mistakes here cost time, money, and reputation. Whether it's misconfigured tap changers, unreliable readings, or repeated site visits, the impact of inefficient testing adds up quickly.

Investing in tools that reduce training time, eliminate unnecessary steps, and deliver consistent results isn’t just smart for crews — it’s smart for business. The MTOU3 gives both field teams and operations managers the confidence to move faster without compromise, making it a strategic upgrade with long-term return.

A single test set that delivers lasting value across teams

The MTOU3 brings together critical transformer tests — winding resistance and OLTC checks — in a single, compact device built for daily field use.

By consolidating functions, it reduces the number of tools needed onsite and simplifies both training and deployment. Crews get a workflow they can follow with confidence. Operations teams get consistent processes and scalable rollouts across regions.

And with a rugged, purpose-built design, it’s built to perform under pressure — not just in ideal conditions.
