Transformers are inherently bidirectional.
It's called a 'distribution transformer', as opposed to a 'power transformer' which is used in the transmission and primary-distribution electrical systems.
There's very little point in having a distribution transformer if its secondary winding isn't connected to a load! So, to answer your question, a 'secondary system' (by which you, presumably, mean 'load'), isn't 'essential' to a distribution transformer, it could just sit there doing nothing!
The transformer ducts are usually made up of strips of transformer board that is glued to the Diamond patter resin coated paper. It is widely used by transformers for manufacturing oil immersed distribution transformer windings.

A distribution transformer IS the term used to describe the utility transformer which supplies a residence.
The maximum efficiency condition in distribution transformer is said to be occurred when iron loss = copper loss

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.)
A transmission transformer steps the voltage up to a very high value so electricity can travel long distances on transmission lines from the power plant to a city or area with low loss. A distribution transformer steps the high voltage back down to a level that can be used for local distribution and use by businesses and homes.
Transformers are inherently bidirectional.
It's called a 'distribution transformer', as opposed to a 'power transformer' which is used in the transmission and primary-distribution electrical systems.
Power transformers are step-up or step-down transformers used in the electricity transmission system, whereas distribution transformers are step-down transformers used in the electricity distribution system.
A '33-kV transformer' is a three-phase primary-distribution transformer, used in the UK's electricity system to step down the 33-kV primary-distribution voltage to the 11-kV secondary-distribution voltage -the lowest voltage used in the high-voltage distribution system. These transformers are categorised as 'power transformers', and are located in what are termed 'primary substations'.
poor cooling mechanisms, and overloading.
low voltage problem may arise due to unbalancing of distribution transformer in your area. please ask your electricity provider to balance load on distribution transformer.
