Electrical hotspots in LV transformers often begin at joints, terminations, and connection points affected by heating, cooling, vibration, mechanical stress, loose connections, or increased resistance. These conditions can develop between inspection intervals and, if left undetected, may progress to failure.
This solution is specifically designed to provide continuous thermal monitoring protection for LV transformers via our Modbus transformer solution (MTS) which is provided in kit form per transformer (various kits are available depending on transformer size).
Sensor looms connects back to the MTS datacard (MTD), which collects and transmits the sensor temperature data, and activates alarms when a fault is detected. The MTD is housed in an external enclosure, along with the LEDs to provide local alarm status.
The low voltage transformer solution is suitable for both new build and retro-fit installation, and is also OEM vendor neutral.
Reduced reliance on periodic inspection
Move beyond snapshot-based inspection with continuous condition visibility between scheduled maintenance windows.
Simple kit-based installation
Use kit-form LV transformer sensors designed to make installation as straightforward as possible.
Retrofit and new-build suitability
Support both existing LV transformer upgrades and new installation requirements.
Earlier detection of developing hotspots
Identify rising temperature conditions before they progress into transformer outages, damage, or operational disruption.
OEM-neutral deployment
Apply continuous thermal monitoring across LV transformer assets regardless of manufacturer.
Continuous monitoring of critical transformer connections
Monitor key LV transformer connection points in real time, including voltage input and output connections and coil tap change connections.

The LV transformer (MTS) thermal condition monitoring solution can be connected in 2 ways.
Our CTM solution is designed as an OEM-neutral solution to LV transformer monitoring, enabling continuous visibility across critical transformer connection points regardless of manufacturer. It monitors areas where electrical hotspots can develop, including voltage input and output connections and coil tap change connections, helping teams identify rising temperature conditions before they escalate into outages or equipment damage.
By providing real-time thermal insight between inspection intervals, the solution reduces reliance on periodic inspection alone. It also supports safer maintenance planning by limiting unnecessary interaction with energized transformer assets. Suitable for both retrofit and new-build LV transformer applications.
