This is what is known as a 1:1, or ISOLATION Transformer. There is no change to the Voltage or Current of the input, but this does provide a separation between the input and output of the transformer. This separation is sometimes required for safety purposes, especially in a medical environment.

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 different of induction transformer and automatic transformer?

Neither of these terms is normally applied to a transformer. You may be thinking of a 'mutual tranformer' and an 'autotransformer'. If so, then a 'mutual transformer' is a transformer which has electrically-isolated primary and secondary windings, whereas an 'autotranformer' (the term, 'auto', is misleading and has nothing to do with the transformer being 'automatic'!) has a common and series winding, meaning that the primary and secondary sides are electrically connected to each other.


A 240V to 480V Step up transformer with a load of 85 amps at 480v what amperage will the transformer draw if the primary is 240V?

Since this transformer has a ratio of 1:2 the load current on the 480V side just has to be doubled. 85 x 2 = 170A on the primary. 40.8 KVA transformer. To prove this just find the KVA of both sides and they should be equal.


Does a 3 phase motor starter with a 120 volt coil need a neutral to the coil?

Usually for this type of installation there is a control transformer installed in the starter enclosure. The primary of the transformer is the motors line voltage and the secondary is the control voltage which is usually 120 volts. In Canada the control transformer needs fusing on the secondary side of the transformer. In the US the transformer needs fusing on the primary and secondary sides of the transformer. The secondary side of the transformer's terminals are labeled X1 and X2. The X2 lead is grounded to the starter's enclosure. From this point out the wire is then termed the circuit's neutral wire. This wire then connects to one side of the magnetic starters draw in coil. Yes, 120 volt coil would require a neutral, this could be derived from the control transformer if it has one or from an external source.


If increase load of secondary side of transformer. why primary side current increases?

The wattage must remain equal on the primary and secondary sides of a transformer. An example to the above statement with a 1000 watt step down transformer. To fine the watts (load) the formula is W = A x V. The primary side of the transformer has the capacity of 1000 W = 4.16 Amps x 240 Volts. The secondary side of the transformer has the capacity of 1000 W = 8.3 Amps x 120 Volts. Using the transformer to its maximum, without overloading it, the primary will be 4.16 amps at 240 volts and the secondary will be 8.33 at 120 volts. As you can see the wattage (load) remains constant only the voltages and current change.

Does a transformer boost electric energy?

The transformer doesn't "boost" energy. If the voltage on the output side is higher than the voltage on the input side, then the current is lower. The power (energy every second) on either side is the product of (voltage) times (current), and that product is the same on both sides of the transformer.

What is the same on both sides of any transformer?

frequency. KVA is also same in both side of a transformer!!! KVA means Kilo Volt Ampere.


What is the number of sides in a hexagon multiplied by the number of sides in a pentagon?

A hexagon has 6 sides, and a pentagon has 5 sides. Thus, if you were to multiply the number of sides of a hexagon with the number of sides of a pentagon, you would get a total number of 30 sides.

Can you determine the number of triangles whose vertices are the vertices of an octagon but none of whose sides happen to come from the octagon?

I bilieve the answer is 16.


If you added the number of sides in a pentagon to the number of sides in a decagon what number would you get?

You would get the number 15 because a pentagon has 5 sides and a decagon has 10 sides. 10+5=15. Your answer would be 15 sides.


Where is the ac compressor located?

The compressor is located outside of the house in a metal box with coils in the sides and a fan in the middle of it to blow air through the coils. the compressor should be located under one of the side panels of the box.


Why does inequality sign change when both sides are multiplied or divided by a negative number Does this happen with equations why or why not?

I cannot tell you why it changes however it does happen with an equation as most inequalities start off in an equation.
