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!

What is the turn ratio of a transformer if the primary voltage is 240V and the secondry is 12V volts?
240 / 12 = 20
What is transformer ratios?
ratio of secondry voltage to primary voltage is called voltage transformation ratio
Does the fuse on the primary side of a transformer protect the secondary side?
Yes, but it's usual to have fuses on both sides of the transformer.
If a dc voltage of 12v is added to the secondary of step down transformer and rating of transformer is 220 input and 12v output what will be the result from primary of transformer?
Adding a DC voltage to the secondary of a transformer will not have an effect on the primary side, as transformers work on the principle of electromagnetic induction which is based on alternating current. The primary side of the transformer will still operate based on the input AC voltage of 220V. The DC voltage on the secondary side will not be transferred to the primary side.
What are the side-effects from transformer oil?
side effects from leaking transformer oils in the early 1970's. Heart, kidney diseases?
What are the precautions using current transformer and potential transformer?
Secondry of CT should never kept open during functioning
What is the turn ratio of a transformer if the primary voltage is 240V and the secondry is 12V volts?
240 / 12 = 20
Does the primary winding VA equal the secondary winding VA when a transformer is loaded?
No, the primary winding VA does not necessarily equal the secondary winding VA when a transformer is loaded. The power output on the secondary side may differ from the power input on the primary side due to losses such as resistive and core losses in the transformer. The transformer's efficiency will determine how close the VA on the primary winding is to the VA on the secondary winding.
What is transformer ratios?
ratio of secondry voltage to primary voltage is called voltage transformation ratio
Why neutral is ground in the circuit?
In the transformer at the secondry side one end of the winding will make star connection means 0 point there will be no voltage at that end if any leake voltage appear at that point it have to ground that what all the neutral points to be grounded
Why you uluminium on primary side of transformer?
This isn't the case. You can have aluminium or copper on primary or secondary side of a transformer.
What the purpose of the H1 terminal on a transformer?
The terminals H1 and H2 an a transformer indicate the primary side of the transformer. The secondary side is usually identified as X1 and X2.
What happens to the current as the voltage is increased by the step up transformer?
Compare a transformer to a balancing act. Both side need to remain equal.The primary side of the transformer is the supply side and the load is connected to the secondary side of the transformer.The load governs the current of the secondary side of the transformer and the voltage of the secondary side must match the voltage that the load required to operate.The ratio of the transformer will determine what the voltage of the secondary side is as compared to the voltage that has to be applied to the primary.The current of a step up transformer will be higher on the primary side that that of the secondary.Apply voltage and current to this concept and you will see that the transformer will remain balanced.The size of the transformer is always calculated from the secondary side of the transformer and the value is written in VA or KVA where V = voltage and A = amperage. Power factor is also taken into consideration when calculating the size of the transformer to be used.
Where is the power distibution box located on a 1998 Chevrolet Silverado?
Its in the glove box. Push the power distribution button on the right side.
Does the fuse on the primary side of a transformer protect the secondary side?
Yes, but it's usual to have fuses on both sides of the transformer.
If a dc voltage of 12v is added to the secondary of step down transformer and rating of transformer is 220 input and 12v output what will be the result from primary of transformer?
Adding a DC voltage to the secondary of a transformer will not have an effect on the primary side, as transformers work on the principle of electromagnetic induction which is based on alternating current. The primary side of the transformer will still operate based on the input AC voltage of 220V. The DC voltage on the secondary side will not be transferred to the primary side.
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.)
