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.
If one transformer of a delta transformer bank fails the bank can be reconnected open delta and operate at reduced efficiency?
yes open all fuses close the primary neutral tap,remove secondary leads off of bad traansformer,tell customer to reduce his load until bad transformer can be replced.
Can you bank three single phase transformers in a delta to grounded wye with one transformer having a different impedance?
yes
What is the procedure to polarity test a 3 phase transformer?
A 'polarity test' is conducted on a single-phase transformer, not a three-phase transformer (or transformer bank). The polarity of a single-phase transformer being important if two transformers are to be connected in parallel, or three transformers are going to be connected to form a three-phase transformer bank.'Angular displacement' is, to a three-phase transformer, what 'polarity' is to a single-phase transformer. So you really should be asking about angular displacement, rather than polarity. Angular displacement, or 'phase displacement', is the angle by which the secondary line voltage lags the primary line voltage.Angular displacement can be determined either by drawing a phasor diagram of the three-phase connection and measuring it, or by looking up the connection in a vector-group chart/table -you would nor normally 'calculate' angular displacement.
Why vector group is required?
There are various ways in which you can connect a three-phase transformer's primary and secondary windings, or in which you can connect three single-phase transformers to create a three-phase transformer bank. For example: wye-wye, wye-delta, delta-delta, delta-wye, etc.For each connection, there is a natural phase shift between the primary and secondary line voltages. This is called the angular displacement (or 'phase displacement') of the transformer connection.If you wish to parallel two three-phase transformers, or two three-phase transformer banks, then their angular displacements must be the same (there are also other requirements not relevant to this answer).A vector group is a method of specifying a three-phase transformer (or transformer bank) method of connection and its angular displacement. Transformer connections from the same group can be paralleled. Those in different groups cannot

What is bank balance versus cash balance?
bank balance:- A bank balance is that amount which is actually deposited in any of the bank. or the amount which has been credited in your bank account. cash balance: - It is an amount which is there in your hand. i.e., it is otherwise called as cash in hand. or else we can say that the hot cash which is there with you right now is called as a cash balance. conclusion:- bank balance is the amount deposited in bank. and cash balance is the cash in hand.

What are the common sources of difference between the balance per book and the balance per bank statement?
Balance per book is company's record and balance per bank is banks record on the bank reconciliation.
