DISSIPATING HEAT from TRANSFORMER
DISSIPATING HEAT from TRANSFORMER
(OP)
Can anybody help me on calculation of getting dissipating heat from transformer? I guess there is a chart or something that I can get the heat that comes out from transformer.
I need the quantity of heat dissipated from 3 transformers in kcal or in Joule
I need this information to calculate the size of the Exhaust fan and supplying louver for substation room.
Room Size: 85'-4"(L) x 30'(W) x 18'(H)
Location: side of the building
Sizes of 3 transformers in substation room:
TR1
2000KVA, 13857.5V, 45.31A, 1066KW, PF=1
TR2
2667KVA, 13840V, 58.13A, 1296KW, PF=-0.96
TR3
2667KVA, 13872.5V, 27.81A, 634KW, PF=1
Supplying Air Temperature via Supplying Louver = 70F
Current Room Temperature of Substation Room = 90F
Thank you very much for your kind replies in advance.

RE: DISSIPATING HEAT from TRANSFORMER
Obviously, the losses are proportional to the load current, and you may have to estimate the load.
Watts measured over time become energy (Watt-hours), which can be converted to Joules (1 Watt-hour = 3600 Joules).
RE: DISSIPATING HEAT from TRANSFORMER
Can anyone help me to find out how to calculate Heat Loss in Watt-Hour from the load loss in Watt?

What DanDel is saying is that ALL losses in a transformer are heat loss. All losses (eddy current, resistance, etc) all end up as heat rejected into the oil or the surrounding air.
