On a stup down transformer what does the xo symbol mean?
On a step down transformer XO symbol denotes the secondary split phase grounding point. This is also where the neutral of the three wire secondary is connected. The transformer connection is known as a single phase - three wire - with one secondary winding.
What is VA burden in electrical engineering?
The term 'burden' is used to describe the secondary load applied to an instrument transformer; the reason for this is so that it is not confused with the 'load' supplied by the high-voltage circuit to which the transformer's primary is connected. A burden is either a measuring instruments (ammeter,voltmeter, wattmeter, etc.) or protective relay, depending on the function of the instrument transformer. 'V.A' is the symbol for 'volt ampere', which defines the 'power' rating of the instrument transformer.
Can you use ordinary transformer in place of auto transformer?
yes we can place auto transformer in place of original transformer
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
What is the difference between isolation transformer and ferromagnetic transformer?
An isolation transformer is usually a ferromagnetic transformer. The question needs to be framed more usefully.

Why transformer rated kva?
The correct symbol for kilovolt amperes is 'kV.A, not kva. A volt ampere is the product of the transformer's secondary rated voltage and its rated current. It is not rated in watts, because the transformer designer has no idea what sort of load is to be applied to the transformer, and it is the load that determines the amount of watts, not the transformer.

What is the secondary amps of 315kva transformer?
The secondary current is determined by the load, not by the transformer. But the load current mustn't continuously exceed the rated current of the secondary winding. To determine the secondary rated current, you need to know the rated secondary voltage of the transformer, and divide 315 kV.A by this figure.Incidentally, the correct symbol for 'kilovolt ampere' is 'kV.A', not 'kva'.
What does the lines between primary and secondary coils of transformer signify?
The voltage in a transformer is transferred from primary coil to secondary coil through electromagnetic induction. There is no physical connectivity between these two. instead they are linked by an alternating magnetic field created in the soft-iron core of the transformer.The two lines in the middle of the circuit symbol represent the core of the transformer.
What is a half transformer and a half transformer?
a hole transformer
Why induction transformer called rotating transformer?
Transformer has windings
Can you use ordinary transformer in place of auto transformer?
yes we can place auto transformer in place of original transformer
How much load should be given on 5 mva transformer?
It depends on what you mean by '5 mva'. Because you haven't used the correct symbol, no-one will know whether you mean '5 millivolt amperes' or '5 megavolt amperes' -there's a HUGE difference! The correct symbol for 'millivolt ampere' is 'mV.A' and the correct symbol for 'megavolt ampere' is 'MV.A'. I hope you can now see the importance of using the correct symbol. To answer your question, the load volt amperes should not exceed the transformer's volt amperes. So, in your case, the load shouldn't exceed 5 mV.A or 5 MV.A -whichever you mean.
What is the function of fans in transformer?
The function of fans in a transformer is to regulate the transformer's temperature.
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
What is center tap transformer?
Center tap transformer is the such kind of transformer that is made to a point half way along a winding of a transformer.
