I have a transformer thats 50MVA
It has a combined load+noload loss of 250kW
Does this give me (a roughly estimated) transformer with an efficiency of 99.5%? - ignore hysteresis etc...
Another engineer says its got an efficiency of 50% and I'm pretty sure thats wrong ..... so just checking :)
sorry should've been more specific..
No major refurbs - like rewinding of core etc, dont do that.
Just oil reclamation, remove moisture etc, refurbish the ancillary equipment etc.

J&P is pretty much the bible isn't it! :) the copy I have is OLD ass tho i think its from the 70s... I also have blume.... also a pretty old copy I tink
Hi,
I am trying to determine the implications of carrying out transformer refurbishments on transformers (only on decent transformers - for those with extremely low DPs we dont touch them). I would like to know if there is a general rule of thumb on how much longer a transformer's life will be...
Cool thx for that peepz. Someone in my company said the SD myers one is too basic and I have the half century manual here with me too.The Doble course sounds great. will definitely try to go to that one
Sorry I wasnt being very clear :)
I want to remove water coolers & put radiators on... (for reasons that arent very relevant here so I wont go into them). so there are currently pumps on there.
I'm trying to decide whether I wanna leave those pumps on or not, and whether or not they will...
I have a 28kHz utrasonic transducer which I wish to operate. I need to build a driver to squeeze max power out of this transducer (specs say approximately 70W) After some discussion a few ideas were thrown around, including using a resonant RLC amp, etc. i would like some advice on how i should...
