What is the current of 1MVA transformer?

This depends on the voltage, and whether it is a three phase or single phase transformer.


How do you design a transformer with three phase 400v input and single phase 2000v output?

By design are you going to wind the transformer yourself? In your design you need a 5:1 ratio. On the output side of the transformer any two legs of a three phase transformer is considered single phase voltage. Good luck on your project.


What transformer do you need if you have primary voltage of 600 3 phase and require 240 volt 1 phase?

A single phase 600 to 240 Volt transformer using two phases of the three phase primary.


How you differentiate between single phase and three phase transformer?

A single-phase transformer works with a single-phase supply, while a 3-phase transformer is used with a 3-phase supply. A single-phase transformer has 2 wires on the primary and secondary (ignoring taps) while a 3-phase tansformer has 3 or 4 wires on the primary and secondary.


What is the procedure to polarity test a 3 phase transformer?

A 'polarity test' is conducted on a single-phase transformer, not a three-phase transformer (or transformer bank). The polarity of a single-phase transformer being important if two transformers are to be connected in parallel, or three transformers are going to be connected to form a three-phase transformer bank.'Angular displacement' is, to a three-phase transformer, what 'polarity' is to a single-phase transformer. So you really should be asking about angular displacement, rather than polarity. Angular displacement, or 'phase displacement', is the angle by which the secondary line voltage lags the primary line voltage.Angular displacement can be determined either by drawing a phasor diagram of the three-phase connection and measuring it, or by looking up the connection in a vector-group chart/table -you would nor normally 'calculate' angular displacement.

What is construction and working of single phase transformer?

The single phase transformer works on the principle of mutual induction. Explanation: When an alternating voltage V1 is applied to a primary winding, an an alternating current I1 flows in it producing an alternating flux in the core. As per Faraday's law of electromagnetic induction, an emf e1 is induced in the primary winding. Where N1 is the number of the turns in the primary winding's induced emf in the primary winding is nearly equal and opposite to the applied voltage V1


How you can find positive and negative in a transformer?

There is no positive and negative on a transformer. Transformers will only pass AC (alternating current), due to the fact that induction will only occur with a moving field. The current has to be changing polarity and intensity continuosly, for the current to be induced in the windings. Both terminals on the output vary, with relation to each other. Put DC into a transformer and the coils will saturate, overheat and probably burn out.

What are possible uses of a single phase 30VA transformer?

To continuously supply a load of up to 30-V.A at the rated secondary voltage of the transformer.


Why would you use a three phase transformer in place of a single phase transformer?

the necesscity of two three phase transformers operating in parallel are as follows...if the one transformer fails to give supply,then another transformer can be used in parallel and hance,continuity of supply can be maintained.one transformer can be easily take out from the supply for repair & maintanance.if the load on the substation increases beyond the rated values of transformer, then another transformer can be used to share rhe load of the substation.

Can you convert three phase 480 volts to single phase 110 volts?

If you have a 220v three phase delta system, the phase-to-phase voltage is 220v single phase; hence, no conversion is necessary. Don't worry about 220-240v rating, the voltage rating is nominal. Your 110v single phase has actually already be taken from a center-tapped transformer on your three phase system.
