What is the angle between no load current and the applied voltage in an ideal transformer?
A: Transformer by itself goes not alter the phases the output can be in phase or out of phase depending how you look at it.
What is the current of 1MVA transformer?
This depends on the voltage, and whether it is a three phase or single phase transformer.
What is the role of magnetizing current in transformer?
connect 3 - phase supply to transformer primary winding.....keep transformer secondary winding open..... apply 3-phase voltage i.e.400v ac, and measure the amount of current flowing in each phase of the transformer primary winding...this current is the transformer magnetising current..... we can keep multimeters in series with the source....so we can measure directly the current readings.....(keep multimeters in current mode, and generally magnetising current will come in terms of milli amps for 400 v )
What is phase shift in three phase transformer?
The phase shift in three-phase transformer from winding of Transformer and determine by vectorgroup of transformer such as YNd1 High voltage connect to wye Low Voltage connect to delta so L.V. lag H.V 30 degree.Answer'Phase shift' or, more accurately, 'angular displacement', is the angle between the secondary line voltages and primary line voltages of a three-phase transformer.
What is the formula to get neutral current in three phase transformer where three phase cureent are given?
Neutral current is the vector sum of the phase currents. You should be able to add up the phase currents from their polar quantities.
What are the Causes of phase angle error and ratio error at Current Transformers?
RATIO ERROR The secondary current is less than the expected value. The secondary is less in magnitude. This diffence is known as ratio error. PHASE ERROR The angle between the expected and actual secondary current is known as phase error.

How do you zero phase current tranformer test?
How do you zero phase current transformer test
What is the phase angle between voltage and current in a purely resistive circuit?
The phase angle between voltage and current in a purely resistive circuit is zero. Voltage and current are in phase with each other.
What is the role of magnetizing current in transformer?
connect 3 - phase supply to transformer primary winding.....keep transformer secondary winding open..... apply 3-phase voltage i.e.400v ac, and measure the amount of current flowing in each phase of the transformer primary winding...this current is the transformer magnetising current..... we can keep multimeters in series with the source....so we can measure directly the current readings.....(keep multimeters in current mode, and generally magnetising current will come in terms of milli amps for 400 v )
Why phase angle is zero when voltage and current are in phase?
1 & 3
Why do you rate a dc machine in watt but a transformer in kilo volt-ampere?
The difference between watts and volt-amperes is due to the relative phase angle, or power factor, between voltage and current. In a DC system, the two are in phase. In an AC system, with only resistance, the two are also in phase. Add capacitance or inductance and the phase angle changes.
A single-phase transformer when supplied from 220v50hz has eddy current loss of 50wif the transformer is connected to a voltage of 330v50hzthe eddy current loss will be?
112.5
How can you fix the output current of phase angle?
Your question doesn't really make much sense. Phase angle is simply the angle by which the load current leads or lags the supply voltage.
At what condition the phase angle equal zero?
That means that the voltage and the current are in phase.
