Comment on Dry Type Transformer Life Expectancy by dennis burns

I have a 13.8 kv / 3000 kva transformer. if i run the transformer at 50% capacity for 10 years then i up the capacity to 90% of the transformer’s output, is the life expectancy less because i ran it in at 50% of it output capacity for 10 years then i up the output capacity to the 90% mark. the reason i ask this question is because we lost a transformer the size i spoke about and we installed a transformer as a temporary and it had been run under the above conditions, does the life expectancy become shorter because when the transformer had been installed years ago at the beginning of its life and the varnish on the coils would have been cooked in at a lower output so when i up the output would that create a problem for how much load it could carry safely.

Many do not understand this concept of weather shield in dry type or air cooled transformers and try to shift to another option there by wasting their time and money considerable. This post could really be an eye opener for them.

Thanks for sharing this. It’s good to know what is actually inside those oil transformers, and those pictures show that power transformers are one of the most dangerous pieces of electrical equipment. Of course this has relation with the large quantity of oil they contain, which is in direct contact with high voltage elements

No. Heat is a transformer’s big enemy. Transformers are pretty dumb devices, but the manufacturers are very smart. They are not going to overbuild a transformer to reliably take such abuse. Years ago some transformers were overbuilt and just seemed to last and last, even when overloaded. But today there are other concerns besides ‘run to failure.’ There are concerns for the conductor sizing, overcurrent protection, cost of losses, low voltage, reliability, consequences of failure, and most important, SAFETY. Don’t do it. MIDWEST

if you have a 750kva dry type transformer 208v primary delta, 277/480v secondary wye grounded….at the secondary side, the transformer will deliver 930.6 amps…however, can you get an additional 150 amp, by overloading it….and if so, can the transformer last 50 years…..
as always, a quick response will be greatly appreciated……Thanks…
