How do you draw phase diagram for transformer operating at load with lagging PF and leading PF?
In order to draw the phase diagram for transformer operating at load with lagging PF and leading PF, you will need to know the equation for the transformer being load free. This constant will help you with the load bearing equation of Np/Ns=Vp/Vs=Is/Ip.
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.
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.
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 meant by rated voltage rated current and rated power of a transformer?
The ratings state the limits on voltage and current for operating the transformer at full load. The rated voltage times the rated current gives the rated VA of the transformer. Transormers are not usually rated directly for power because this depends on the power factor of the load applied.
What is the minimum load require to put transformer?
A transformer requires a 75-kVA minimum load in order to be set.
What is the problem of operating a on-load furnace transformer with center tap?
What is the problem of operating a on-load furnace transformer with center tap
When operating a no load tap changer on a transformer what should be done first?
First isolate the transformer
What is the minimum load have to go for a new transformer?
All transformers have a power rating given in kVA which determine the maximum load that can be connected to that transformer.
Why transformer power factor taken unity?
It isn't! A transformer operating at no load has a very low power factor.

What is the problem of operating a power transformer without load?
There is no problem as such. Whether you would want to, or need to, is another matter.

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
