In an ideal xmfr, the power in equals power out and only the voltage and current
changes.
If the transformer is three phase the calculation is I = 30,000 / 1.73 E. If the transformer is single phase the calculation is I = 30,000 / E. (Where I = current and E = secondary voltage) It is important to note the voltage in the first formula is line to line (typically how it is specified in three phase power systems), and the second formula it is line to neutral.
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
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.
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).
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.

for three phase the calculation is 30,000 = 1.73*V*I - simple as that. For single Phase the calculation is 30,000 = V*I - simple as that It is important to note the voltage in the first line is Line to Line (typically how it is specified in three phase power systems), and the second line it is Line to neutral. A 30KVA transformer is the same as 30,000VA to find out the Amps you need to divide the voltage if the transformer is single phase for example: 30,000VA / 480V = 62.5 Amps The calculation for a 3 phase transformer is the VA / voltage / 1.73 for example: 30,000VA /480V / 1.73 = 36.12 Amps
rectifier transformer converts acinto dc.but,power transformer convert step up or step down ac energy without changing frequency
The size of grounding wire is based on the amperage output of the transformer. The voltage of the transformer needs to be stated. Without this voltage a calculation can not be made. Amps = Watts/Volts = 30000/?.
To determine the transformer rating in KVA for a 55 kW motor, you can use the formula: KVA = KW / Power Factor. Assuming a typical power factor of 0.8 for motors, the calculation would be KVA = 55 kW / 0.8 = 68.75 KVA. It's advisable to round up, so a transformer rated at 75 KVA would be appropriate to ensure adequate capacity.
Transformer Inductance?
B.I.L. stands for Basic Impulse Level for the transformer. It should be on the faceplate of the transformer.
