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 main different between the power transformer and voltage transformer?
Voltage Tarnsformer transforms only voltage. While power transformer transforms both voltage and current.
Can a a electric substation in a city use transformers to increase the power output?
No! A transformer changes voltage levels, not power levels. In fact, the output power of a transformer is actually a little lower than its input power, due to the efficiency of a transformer.
What is the use of a transformer with turns ratio 1?
isolation if you are in the usa and must service electronics the neutral is grounded the power supply is a voltage doubler one side is 170v+ to ground the other is 170v negative to ground so if you run the power thru the transformer first you stand a better chance of staying alive these transformers are quite often used to trigger scrs or triacs for the same reason
Why the power factor of load is not fixed on the transformer?
Because the transformer designer does not know the power factors of the different loads that might be connected to it. The way round this probem is to specify the voltage and the maximum current that the transformer can supply, then multply them together and print the VA, kVA or MVA rating on the transformer. Then it's up to the user to comply with this rating to avoid damaging the transformer.
What is a transformer and its functions?
Voltage transformer or potential Transformers are used in conjunction with Current transformers for metering and protection purpose in HT and LT power system.
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 a LT panel?
An LT panel, or Low Tension panel, is an electrical distribution panel that receives power from a transformer and distributes it to various electrical loads at a lower voltage, typically below 1000 Volts. LT panels are commonly used in industrial, commercial, and residential buildings to control and protect electrical circuits.
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 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 WT Stand for?
LT = Limited WT= Work Truck
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 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 does LT stand for on a truck?
Light Truck
Bil of power transformer?
B.I.L. stands for Basic Impulse Level for the transformer. It should be on the faceplate of the transformer.
