Power and Electrical Transmission
Instrumentation, online monitoring and services for power generation, transmission and distribution: predictive diagnostics for power transformers and reliable measurement at every point of the grid.
From periodic sampling to continuous monitoring of the grid's most critical asset
The power transformer is one of the most expensive and critical assets on the electrical grid, and its failure rarely gives advance warning. Laboratory dissolved gas analysis delivers a snapshot: between one sample and the next, an incipient fault can evolve unseen. Online monitoring turns that diagnosis into a continuous trend and enables condition-based maintenance.
We don't install an isolated monitor: we integrate instrumentation, traceable calibration, telemetry and data intelligence on a single risk-mitigation platform, so that every decision about a critical asset is made with reliable, traceable data.
Online diagnostics for power transformers
Continuous monitoring of dissolved gases, hydrogen, moisture and temperature in the insulating oil, with real-time trends as an early warning of developing faults. Built for the assets where an unplanned outage is not an option.
- Critical power transformers in transmission and distribution

An integrated platform, not just another supplier
In high-criticality assets, the value of a data point depends on the entire chain behind it: the instrument, its calibration, the telemetry that carries it and the models that turn it into foresight. AKRIBIS One brings the ecosystem's units together so that chain has no loose links.
