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.
Is it necessary to connect a fuse at the secondary side of a current transformer?
Definitely NOT! An open circuit (across a melted fuse for example) on the secondary side of a current transformer is subject to a dangerously-high voltage, so a fuse must not be fitted. The secondary side of a CT must never be open circuited.
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.
If the fuse of the secondary side of the transformer blows what are the test to be conducted to check if the transformer is defective or not?
1st make sure the power is turned offDisconnect one lead on primary side of transformer and using an ohm meter check for continuity. You will probably get a low ohm reading if you get no reading the windings are broken and transformer is no good2nd test using ohm meter again check for winding to ground you should get no reading. If you get a ohm value the transformer is shorted to groundRepeat these tests on secondary sideWith power on and fuse removed with a voltage meter check for power on secondary sideIf it is okay turn off power and install fuseIf fuse blows again check for shorts in circuitRemember to be careful when power is turned on
What are the side-effects from transformer oil?
side effects from leaking transformer oils in the early 1970's. Heart, kidney diseases?
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.
What is the amp rating of 100va transformer?
The amp rating for a 100VA transformer will vary depending on the actual voltage of the transformer. Transformers have both a primary and a secondary voltage.
Is it necessary to connect a fuse at the secondary side of a current transformer?
Definitely NOT! An open circuit (across a melted fuse for example) on the secondary side of a current transformer is subject to a dangerously-high voltage, so a fuse must not be fitted. The secondary side of a CT must never be open circuited.
What wires conductors would go under x lug in a transformer?
The primary side of a transformer is identified as the H side, eg. H1,H2,H3,H4. The secondary side of a transformer is identified as the X side. Eg. X1, X2. Usually X1 goes to a fuse and then to the load, X2 is usually the neutral side and is grounded to the body of the transformer.
How do you calculate rating of 11 kv transformer?
The KVA rating of a transformer is based on how much heat the transformer can dissipate. The BIL rating is based on how well the windings are insulated. There are other "ratings" as well. Rough calculations can be done, but tests are generally performed to prove the calculations (transformer designers will design on the conservative side to insure the transformer meets specification). These type of calculations are best done by a computer. You will struggle to determine the hot spot max temperature rise in a transformer by hand.
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.
Why does the primary side of a step down transformer burn out and not the secondary of a 480V to 240V transformer?
Sounds like the wrong size fuse protection was used. The transformer should be protected to its kva capacity.
Replaced the thermostat and the furnace works but wont turn on?
Sounds like you might have a blown transformer, or a blown fuse on the transformer. Hope for the fuse. Its on the Furnace. Be sure your white wire is on the heat side of the thermostat, and the red wire is on the correct terminal also. The transformer can be checked with a voltmeter.
What is line side amps for 1000kva transformer?
It depends on the voltage on line side. KVA is simply thousand volt-amps, so you need to know voltage in order to calculate amperes.Another AnswerThe rated primary current is the rated apparent power of the transformer, divided by the rated primary current. However, the actual primary current is determined by the actualsecondary load current in proportion to the reciprocal of the turns ratio.
How do you convert 480v to 120v?
to derive 120 volts from 480 volts you have to use a transformer, based on your needs. If you needed 100 amps at 120 volt single phase you would need a 12kva transformer. This is just an example.
If the fuse of the secondary side of the transformer blows what are the test to be conducted to check if the transformer is defective or not?

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.
