Maximum Load Factors

Maximum Load Factors

Maximum Load Factors

(OP)
Hey guys, I was just wondering if anyone had on hand the Maximum Load Factors for various transformers? any help would be appreaciated, Thanks.

RE: Maximum Load Factors

Load factor is the ratio of the average to peak load.  This is very much dependent on the loads served by the transformer.  It is not a number that relates to a particular transformer.

If this is your question, where are you located and what type of loads are being served?  Also what transformer sizes are you talking about?

RE: Maximum Load Factors

(OP)
Well I was basically wondering if for instance a Low Voltage Dry transformer had a lower/higher load factor than any other types mainly used.  I am not that experienced with the use of transformers yet so its hard for me to explain any more.  Thanks for the help though...

RE: Maximum Load Factors

If you are asking if you can load up a dry-type transformer the same as an oil-filled, the answer is basically yes, subject to ambient temperature limitations, etc.  Short-term overloading might be another matter.  

But load factor is a function of the load, not the transformer.  

RE: Maximum Load Factors

Usually , but not like a rule , you can take a factor of 0.8 for oil transformer , and 0.9 - 0.95 , for dry transformer.
Everything depends on manufacturer.
Example , if you have S=630kVA, you can "count" on 630*0.8=504kW , oil transformer , and 630*0.92=580kW , dry transformer.
