What does BIL stand for in electrical high voltage substation?
BIL stands for Basic Impulse Level, it is the impulse voltage or power ( in the case of testing a transformer) or surge voltage in the case of lightning or switching, that a transformer or any other electric device is able to with stand. It refers to maximum voltage a device can with stand with out insulation breakdown which leads to a short circuit.
What is the difference between power transformer and instrument transformer?
A power transformer is used to provide power (to your home, for example), an instrument transformer is used to measure voltage or current (for metering, for example).
How a rectifier transformer deffer from a power transformer?
rectifier transformer converts acinto dc.but,power transformer convert step up or step down ac energy without changing frequency
Why the power factor of a transformer is poor at no load?
The inductance of the transformer is much higher than the resistance of the transformer, resulting in very low real power losses (in watts), but some reactive power (vars).
What does the power rating of a transformer imply?
Knowing the power rating of a transformer will help an operator use the transformer within its design limitations with regard to heating of the windings and their insulation.

What is meant by the term ideal transformer?
ideal transformer is that which has no power losses.if any transformer transfer power to secondary without power loss then that call a ideal transformer
Is transformer an amplifier?
No. In an amplifier, Power Out > Power in. In a transformer Power Out ~= Power In (minus internal losses). An AC generator is more like an amplifier than a transformer.
What is the difference between power transformer and instrument transformer?
A power transformer is used to provide power (to your home, for example), an instrument transformer is used to measure voltage or current (for metering, for example).
What is basic insulation level of 3.3KV Transformer?
The Basic Insulation Level (BIL) of a 3.3 kV transformer typically refers to its ability to withstand transient overvoltages. For a 3.3 kV transformer, the BIL is often around 12 kV for lightning impulse and 8 kV for switching impulse. These levels may vary based on specific standards or manufacturer specifications, but they generally ensure the transformer can handle expected electrical surges without failure. Always refer to the manufacturer's guidelines or relevant standards for precise values.
What will happen you f the rated power of transformer is changed?
You cannot 'change' the 'rated power' of a transformer except by changing the transformer for another one. You can, though, operate the transformer below its rated power or, for short periods of time, operate the transformer aboveits rated power.

What does LT stand for in power transformer?
Transformer Inductance?
When was Adams Power Plant Transformer House created?
Adams Power Plant Transformer House was created in 1895.
Why transformer power factor taken unity?
It isn't! A transformer operating at no load has a very low power factor.
Why the power factor of a transformer is poor at no load?
The inductance of the transformer is much higher than the resistance of the transformer, resulting in very low real power losses (in watts), but some reactive power (vars).
