What is transformer tapped secondary?
A 'tap' is a connection made part-way along the length of a transformer's winding. In the case of a standard North American distribution transformer, the 240-V secondary winding is centre tapped and earthed, providing both a 240-V (across the entire secondary) and a pair of 120-V (between each end, and the centre tap) supplies to a building.

Can be a distribution transformer be bidirectional?
Transformers are inherently bidirectional.
What is the difference between an ordinary transformer and a center-tapped transformer?
An ordinary transformer has two input/output terminals but a center tapped transformer has 2 input and 3 output terminals. One is taken from the center for a ground connection. This causes it to get 50% of the actual value. And ordinary transformer contains 2 windings. An autotransformer has one.
What kind of transformer is used to change the voltage of electric current in transmission lines before it enters houses in a neighborhood?
It's called a 'distribution transformer', as opposed to a 'power transformer' which is used in the transmission and primary-distribution electrical systems.

What is the maximum transformer rating for distribution transformer?
100MVA

What is uses of tapped coil?
If question is about a transformer's tapped coil then the taps are a way of getting different voltages from one transformer. The end of the transformer's coil is the common point and the taps to this common point will give different voltages depending on where in the coil the taps are taken from.
How do you use distribution transformer as temporary power supply to residential housing?
A distribution transformer IS the term used to describe the utility transformer which supplies a residence.
Where are center tapped transformers used?
The transformer that feeds your house is a center tapped transformer. Primary 7200, Secondary 240. The 240 volt secondary is center tapped to give you 120 volts on either side of the tap. Hence house voltage is 120 / 240 volts.
What is maximum efficiency condition in distribution transformer?
The maximum efficiency condition in distribution transformer is said to be occurred when iron loss = copper loss
What is approximate turns ratio of the centre-tapped transformer used?
It depends on the voltage ratio of the transformer. If you know the primary and secondary voltages, then you can work it out for yourself.
Why transformer winding are tapped in the middle?
Transformers are not necessarily centre tapped, although some are. In North America, for example, the secondary-side (240-V) of a distribution transformer is indeed centre tapped. It is at this point which it is earthed (grounded) to provide the neutral conductor to a residence's supply. The outer ends of the winding are then at 120 V with respect to that neutral -thus providing the residence with a combination of 230 V and 120 V. Lighting and (120-V) receptacles are then connected between one or other of the outer terminals and the earth terminal, while (240-V) heavy appliances are connected between the outer terminals. European distribution transformers are not connected in this way; they do not have a centre tap secondary.

What is the difference between an isolation transformer and distribution transformer?
in isolation transformer earthing is not provide on secondary side but in ordinary transformer neutral of secondary side is earthedAnswerAn isolation transformer is a 1:1 ratio transformer; its function is to electrically isolate the secondary side from the primary side without changing the voltage. An example of an isolation transformer is the one used in a shaver socket.A distribution transformer is a step-down transformer, used within the electricity network's distribution system. An example of distribution transformer is a pole-mounted transformer, supplying low voltage to residences.(Of course, all mutual transformers provide electrical isolation between primary and secondary.)
If the loads were only 240v on a single phase 240v system with a center tapped transformer the neutral conductor would carry?
If a load were only 240 volt on a single phase 240v system with a center tapped transformer the neutral conductor would carry no current.
