D is for the primary winding -> triangle Y is for the secondary winding -> star N -> secondary grounded 5 -> phase difference 180 degrees/5 = 30 degrees

What is the secondary voltage of a transformer with the turn ratio of 5 to1 and primary volts of 200?
The secondary voltage of a transformer with a turns ratio of 5 to 1, and primary voltage of 200 is 40. (5 to 1)
What are the factors affect the magnitizing inrush current in power transformer?
1- residual flux existing before enegizing the transformer . 2- size of transformer . 3- size of power system. 4- type of magnetic material of the core. 5- the method of energizing the transformer.
A transformer has a primary volt of 240v and a secondary volt of 48v what is the turn ratio?

If a transformer has 20 primary windings and 100 secondary windings and the secondary voltage is 25 what is the primary voltage?
Transformer step-up/step-down voltage is turns-ratio, so if a transformer has 20 primary windings and 100 secondary windings (a turns-ratio of 1 to 5) and the secondary voltage is 25, then is the primary voltage is 5.
What is the impedance of a transformer?
Impedance (Z) voltage is the amount of voltage applied to the primary side to produce full load current in the secondary side. It is usually listed on the transformer nameplate, expressed as a percent, and measured by conducting a short circuit test.
Give you a phasor diagram of dyn 5 and dyn 11?
could you give a schematic diagram of vector dyn 1
Does a transformer have two coils if yes how is the voltage calculated?
the most basic transformers have at least two coils, a primary and a secondary. A transformers nameplate will provide you with the max allowed voltage and current, as well as a voltage per turn ratio. for example a step down transformer could have a primary of 120 volts and a secondary of 24 volts this would give you a ratio of 5:1.

What is impedance voltage in a transformer?
Power transformers have an impedance (Z) rating that is listed in %. So the nameplate might state 5% Z for example. What this means is that when the secondary conductors are bolted together then 5% of the rated primary voltage is applied and will generate 100% current in flow in the secondary. Example: you have a 75KVA Delta-Wye 5% Z transformer with a 480V primary rating and 208/12 secondary rating. The amp rating of the secondary is 208A [75,000/(1.732x208)] So if you applied 24VAC to the primary with the secondary bolted together with busbar then you would have 208A of current flow.
What is the secondary voltage of a transformer with the turn ratio of 5 to1 and primary volts of 200?
The secondary voltage of a transformer with a turns ratio of 5 to 1, and primary voltage of 200 is 40. (5 to 1)
When does The transformer 2 toys come out?
It comes out 5/30
How much is 1 dyne?
1 dyn = 1 g·cm/s² = 10−5 kg·m/s² = 10−5 NThe dyne per centimetre is the unit traditionally associated with measuring surface tension
What are the factors affect the magnitizing inrush current in power transformer?
1- residual flux existing before enegizing the transformer . 2- size of transformer . 3- size of power system. 4- type of magnetic material of the core. 5- the method of energizing the transformer.
How do you get 3.5 VAC from 120 VAC?
The most convenient way of changing AC voltages is with a transformer. Depending on what the load amperage needed will govern the sizing of the transformer. These types of transformers just plug into the wall receptacle for the primary 120 voltage side. For the secondary side you just need to find an adapter that outputs 3 to 5 volts AC. Read the nameplate on the adapter because a lot of them have a rectifier in them that changes the AC output voltage to DC output. Do not use the DC output adapter on an AC required load.
How long does the neon sign last?
Average 8-15 years for the sign, and 5-7 years for the transformer. The transformer can be replaced. The neon can be recharged.
Does 110 volts cost more if uses stepdown trasformer?
If you have to pay for the stepdown transformer, yes. If that is provided free, there is a small loss of energy in the transformer, maybe about 5%, and it depends on whether the meter is installed before or after the transformer.
