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.
Yes, but it's usual to have fuses on both sides of the 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.
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.
In the vector group notation YNyn0(d), the "(d)" indicates the phase displacement between the primary and secondary sides of the transformer. Specifically, it denotes a phase shift of "d" degrees, which is typically a specific value like 30, 60, or 90 degrees. This phase shift is important in determining how the voltages and currents are related between the two sides of the transformer, impacting the overall performance and application of the transformer in a power system.
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.
They are under the coils, along the sides of the intake.
Yes, but it's usual to have fuses on both sides of the transformer.
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.
Most people will think that the 2 poles will attract the most number of clips but actually the part which can attract the most number of clips are the sides near the 2 poles ____________ | N S | |___________| ^ ^ here here
frequency. KVA is also same in both side of a transformer!!! KVA means Kilo Volt Ampere.
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.

The inequality sign flips when both sides of an inequality are multiplied or divided by a negative number because the direction of the relationship between the two values reverses. For example, if ( a < b ) and we multiply both sides by -1, the inequality becomes ( -a > -b ) since multiplying by a negative number changes the order of the values. This does not happen with equations because equations represent equality; multiplying or dividing both sides by a negative number does not change their equality.
I bilieve the answer is 16.
The inequality symbol changes when you multiply or divide both sides of an inequality by a negative number because the order of the numbers on the number line reverses. For example, if ( -2 < -1 ), multiplying both sides by -1 gives ( 2 > 1 ). This reversal does not happen with equations, as both sides can be manipulated equally without changing their equality, regardless of whether they are multiplied or divided by a negative number. Thus, while inequalities require careful handling of the sign, equations do not have this restriction.
I cannot tell you why it changes however it does happen with an equation as most inequalities start off in an equation.
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.
