Introduction
Some of the most common failures on transformers are in the subsystems that are physically located outside the main enclosure or tank of the transformer, making them suitable targets to monitor with infrared sensors. The operation of the transformer is only as good as its w
After our first article on transformer cores, we are here with our second article on transformer coils. In this article, we will talk about the effects of Eco Design Directive losses on coil design and production.
In general, we can say that the core cross-sections (diameters) will incr
Very soon, Tier-2 is coming and it is going to change many things. New EcoDesign Directives have to be applied. In this article series, we are going to explain step by step how they are changing and how our transformer design software adapt.
After EcoDesign revision, as requested lower
POWER TRANSFORMER COOLING
Foreword from the Editor in Chief
When it comes to the cooling of transformers, there are a lot more factors to be considered than one would think. Laura Vandiver has laid out a great case for decision making for specifying, repairing, upgra
Foreword from the Editor in Chief:
It amazes me to see how rapidly things can change in the power industry. Take for example the term “Floatovoltaics”. It sounds like something out of a Star Trek movie. “Mr. Spock, prepare the floatovoltaics for landing on the surfac
Foreword from the Editor in Chief
Everything ages, rusts, or decays. Even electrical system components. This article came about after I did an interview with Maria Lamorey for a PPG profile. Her background and knowledge on coatings and their ability to arrest the onset of corrosion wa
Foreword from the Editor in Chief
Did you ever battle with a transformer that had a dangerously high operating temperature? Transformer operating temperatures are an extremely important parameter for the industry. This will determine to a great extent the actual time the unit can be u
Introduction
Bushings are usually reliable elements of any electric supply system, but all bushings have failure modes and all bushings will eventually fail: some relatively slowly, over weeks or months, and some relatively rapidly, over hours [1]. The cause of failure could be a combin
