Dear Readers,
Digitalisation as the subject for this year’s special edition has been chosen by the readers and that gives it the highest relevance.
Even though digitalisation is today’s buzzword, yet I often hear people asking what it exactly represents in the field of transformers. So, I am taking the liberty of attempting to explain it.
Looking back, I recall many examples where processes have been changed, step by step, from traditional to digital. Over time, the extent of the changes has grown, creating a common trend of making things digital(ly). Therefore, digitalisation is not something that has materialised out of thin air. Rather, it is a culmination of different processes that have been evolving over the last two or three decades, or even longer.

Vibration-measurement-based condition monitoring
A transformer's winding modal characteristics (e.g., natural frequencies, mode shapes) are largely determined by its structural stiffness and mass distribution.
Necessary investments and maintenance of transformers become more predictable
With the TESSA® Asset-Management SUITE, MR offers a modular customer-centred solution for the asset-performance-management
Alberto Prieto – Global Portfolio Manager and Digital Lead for Transformers at Hitachi ABB Power Grids
Hitachi ABB are leaders in design tools, monitoring options and in the validation models and tools available to interpret a transformer’s condition and overload.
TXpert™ Ecosystem – Transforming performance
Electrical power landscape is, however, changing and will continue to change at an accelerated rate with more change in the next 10 years than in the last 100.
Intercontinental Hotel in Singapore adopts digital distribution transformers from Hitachi ABB Power Grids
Based on the hotel's standard operating conditions, the asset is expected to see a drop of 40 % in failure rate and increased life extension by up to 50 %
Demystifying online DGA monitor specification Advertorial Hitachi ABB Power Grids
For detecting desired faults it is essential to combine the right types of the online DGA monitors
Digitalization of renewable resources, the path to a more reliable electrical network
Electricity has become a vital part of everyday life and is required for almost everything we do, and transformers are one of the most critical elements in any power...
Fleet digitalization for increased reliability and maintenance optimization
Digitalization is a crucial element that initiates changes in the whole transformer lifecycle, how they are designed, operated, maintained, or decommissioned
AI – machine learning algorithms applied to transformer diagnostics
Statistical learning has a different interpretation for each of the above-indicated algorithms.
The next generation of energy transmission – The beneficial role of digitalisation in power grids
Today's networks require more complex and reliable controlling algorithms, and sometimes an agile architecture could be the right choice
Total gas pressure for automated transformer condition assessment
A transformer’s lifetime is primarily determined by the condition of its solid insulation.
Successful application of AI techniques: A hybrid approach
It is common for a subject matter expert or a technician to analyse and evaluate all available data to make decisions about actions and interventions.
Transformer noise
Transformer noise comes from the core due to the magnetostriction effect, from the current flowing through windings, as well as from the fans or other equipment
Digital Condition monitoring for smart transformers
Real-time diagnosis of condition-monitoring data can maximise the benefits of a digital transformer
An intelligent system for condition assessment of power transformers
Many utilities have migrated from the conventional time-based to condition-based maintenance.
Think of a number…
Does everyone understand what the AHI really means?
