You need to discuss with a transformer manufacturer, because modifications will need to be made. The transformer name plate will say the top rating of the transformer (I'm assuming in this case it is 30MVA). This top rating is generally limitted by heating. So to uprate, you need to modify the cooling system - add more or bigger fans, add pumps, etc.
In my area, loading as high as 125% of max rating of Transformers is allowed on a "short term" basis (in general), which gives system operators time to shift load without dropping customers.
If 30MVA is the base rating, I see typical values of 166% and 186% for ONAF1 and ONAF2 (oil natural, air forced level #1 and #2). This is something that is specified when ordering the transformer, so it may be different in your case (look at the nameplate!). The 30MVA base transformers I've seen, therefore are rated at 30/49.8/56MVA (at 65 degree C).
What else can I help you with?
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 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.
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.
Why does the power factor of a load affect the voltage regulation of a transformer?
The power factor of a load affects the voltage regulation of a transformer because it influences the reactive power flow and the impedance of the transformer. A low power factor, indicating a higher proportion of reactive power, can lead to increased voltage drops across the transformer’s impedance, resulting in poorer voltage regulation. Conversely, a high power factor reduces reactive power losses and improves voltage stability. Thus, maintaining a good power factor is essential for optimal transformer performance and voltage regulation.
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 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?
Bil of power transformer?
B.I.L. stands for Basic Impulse Level for the transformer. It should be on the faceplate of the transformer.
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).
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.
