Over Heating Transformer

iOperate · January 23rd, 2009, 07:09 PM

Guys, I have an over heating 45KVA transformer. Had it scanned and the guy freaked out. What may be causing this? Could it be a grill?

What did the scan reveal?

Little Jonny · January 23rd, 2009, 07:19 PM

BTW, what does the transformer cater/supply to?

It revealed overheating so much the guy who scanned it wanted to cook his breakfast sausages and pan cakes on the transformer. Wow, that's crazy.

Maybe the transformer is overloaded.....................

Assuming its not overloaded, what are some of the other possibilities?

sparky · January 23rd, 2009, 08:07 PM

poor connections , unbalance loading , lack of air flow around the transformer,

iOperate · January 24th, 2009, 06:55 PM

Will there be a charge for an opinion? We already have a base building electrician.

Sparky, talking about a hot transformer, even the wires running from the transformer (load side) is unusually warm. I am really concerned.

ok. I'll PM you my contact details.

The transformer feeds a computer room a few floors below. Pretty long run. Now that I think about it, the computer room has slowly but surely expanded and added more equipment over the last 10 years but the transformer has remained the same. A major electrical outfit recently added a 5 ton Liebert A/C to the same transformer. Doing a load test would be a good idea, wouldn't you think?

sparky · January 24th, 2009, 07:28 PM

I think they should have done a load test before adding any new eqipment........................

iOperate · January 24th, 2009, 07:36 PM

Well they never did in the last 5 years since the transformer is in our mechanical room. They dont have access to it. However, they continued to add 2 large UPS's and 4 main frames and a 5 ton Mr. Slim A/c to it over the years. Now they've added another 5 tons for stand-by cooling.

I've PM'd you my contact details. I start at 7am on Monday. Call when you arrive and I'll meet you at the loading dock. Thanks Sparky.

Hey Sparky, dont do it for free. Make the man buy you breakfast or something. There must me a Golden Griddle somewhere you can goafter.
