What type of transformer is needed before the electricity from the Power Station is sent into the National Grid?
From the Generator station, the voltage is sent to a step up transformer. Transmission at higher voltages is used to over come line loss over the miles of transmission.
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.
Would you install three-phase transformer or bank of three single phase transformer in a large power station and justify by comparing the two schemes?
A three-phase transformer bank is often used in power stations because it is easier to construct and transport very large single-phase transformers, compared with constructing and transforming an equivalent-capacity three-phase transformer.
What does LT stand for in power transformer?
Transformer Inductance?
What is the main different between the power transformer and voltage transformer?
Voltage Tarnsformer transforms only voltage. While power transformer transforms both voltage and current.
What is tie transformer?
It is a step down transformer which is used to supply the electrical power to the station transformers and the colony transformers
Why generating station capacity mentioned in KW even though alternator rating is in KVA?
In generator station the power which produced is real power the real power to me mentioned in its's factor so it is mentioned as KW or MW. In transformer there is no effect of change the power factor (ie:cos,phi) and the power which transfer do not changes its frequency. so, in Transformer and generator it is mentioned as KVA.

What type of transformer is needed before the electricity from the Power Station is sent into the National Grid?

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).
Would you install three-phase transformer or bank of three single phase transformer in a large power station and justify by comparing the two schemes?
A three-phase transformer bank is often used in power stations because it is easier to construct and transport very large single-phase transformers, compared with constructing and transforming an equivalent-capacity three-phase transformer.
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 is meant by the term transform?
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
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
What does LT stand for in power transformer?
Transformer Inductance?
