Heat load is calculated by the following equation Q=m*cp*deltaT
m=mass flow rate
cp=specific heat
deltaT=difference in temperature

Function of no-load in transformer in a open-circuit?
To calculate the no load current from transformer & core loss is also calculated.
Why are short time rating of transformer is high?
Because a transformer is a big lump of metal that takes time heat up, so if the load is on and off in a short time, the load rating can be exceeded.
Can i Over load an oil filled transformer?
Any transformer can be overloaded by applying a load above the capacity rating of the transformer.
How is a 100 MVA transformer cooled?
Large transformers are filled with oil which circulates to a radiator to get rid of excess heat. A 100 MVA transformer should waste about 1 MW of power on full load, 0.5 MW on no load.
Can you load a transformer by a pure capacitive load?
No

Is a transformer load inductive or capacitive?
A transformer is fundamentally a set of coils; therefore, a transformer is an inductive load. However, by "transformer load", you seem to mean "the load that is connected to a transformer". Whether that load is inductive or capacitive depends mostly on what is hooked up to the transformer.

Because a transformer is a big lump of metal that takes time heat up, so if the load is on and off in a short time, the load rating can be exceeded.
Difference between off load transformer and on load transformer?
Hope this helpsAn "OFF-Load tap transformer" can only have it's tap adjusted when it is De-energized,while the "On-Load tap transformer" can adjust its tap under load conditions.Kind RegardsHammad KhanUniversity of Western AustraliaAnswerAn 'off load' transformer is one whose secondary is open circuited, and not supplying a load. An 'on load' (not 'load') transformer is one that is connected to a load.
How do you load a transformer?
Anything that draws energy from a supply is a load. So you 'load' a transformer by attaching a lamp, a motor, etc., to the transformer's secondary windings.
Can i Over load an oil filled transformer?
Any transformer can be overloaded by applying a load above the capacity rating of the transformer.

No-load and full load transformer?
A: a transformer will follow the rule of input output ratio with no load. As soon as a load is applied there will be changes in the ratio
Can you load a transformer by a pure capacitive load?
No
When is the efficiency maximum in a transformer?
the efficiency is maximum in a transformer when no load loss is equal to load loss.
What is zero current transformer?
It is a transformer with No load attach to it.
What do you mean by no load of transformer?
Transformers voltage ratings are typically at full load. For instance, A 24 VAC, 10A transformer will have a terminal voltage of 24 when it is feeding 10 amps to a load. Since the transformer windings have some resistance, the transformer designer has to wind the transformer to put out more than 24 volts, since some of the voltage will be lost, dropped across the resistance of the secondary windings. But, according to Ohm's law, the voltage dropped across a resistance is proportional to the current (E=IR). If we take away the 10A load, there is no current, and therefore no winding voltage drop! The excess voltage the designer built in now appears at the terminals. This is the no-load voltage. In my example above, when we remove the 10A load, the output voltage of the transformer might rise to 26.4V. We would say the no-load voltage of that transformer is 26.4V The ratio of full-load voltage to no-load voltage is called the transformer's "regulation factor". It is calculated as: (no-load voltage - full-load voltage) / full-load voltage * 100. Ours is: ((26.4 - 24) / 24) * 100 = 10%.
