Why the need of harmonics in single phase transformer?
Harmonics are really not needed in single phase transformers.
Why is the Neutral fundamental in a three phase Y-Y Transformer connection?
Suppression of harmonics
Can a transformer that operates on 60hz also operate on 50hz?
Yes, but it may generate more harmonics
Why phase displacement is maintained between primary and secondary windings of the transformer?
To eliminate certain harmonics.
What is the reason of harmonics in transformer and induction motor?
To be very brief, Harmonics are caused because of magnetising current flowing in the primary of transformer, which cause deaviation from the ideal sinusoidal waveform producing peaky currents in the primary. Due to this the core of the transformer gets saturated and the wave form produced in the secondary also gets distorted.
What is triplen harmonics?
The triplen harmonics are defined as the odd multiples of the 3rd harmonic (ex. 3rd, 9th, 15th, 21st etc.). Triplen harmonics are of particular concern because they are zero sequence harmonics, unlike the fundamental, which is positive sequence. The consequence of this fact is that the magnitude of these currents on the 3 phases are additive in the neutral. This can lead to very large currents circulating in the neutral, and unless the neutral is sufficiently oversized this can present a fire hazard. These currents can also circulate in the transformer causing significant overheating there too. Single-phase power supplies for equipment such as electronic ballasts and PCs are the most significant source of Triplen harmonics
Why excitation transformer vector group is only DY5?
This is basically to reduce the harmonics injected back in the grid which are generated because of the controller rectifier circuit (Thyristor Bridge - B6C) after the transformer secondary.
What is harmonics in a transformer?
When discussing harmonics in relation to transformers, generally you're thinking of harmonics in the current waveform - if it's a 60Hz transformer, the 2nd harmonic would be 120Hz, and is usually very high on transformer energization (referred to as inrush current). The nonlinearity of the core can result in core saturation under multiple different conditions, which tend to produce harmonic currents.
How do you surpres 3rd harmonics?
you match the frequencies but with a 90 degree phase shift
Determine second third and 12TH harmonic of a sine wave?
A sine wave has no harmonics. It only has a fundamental, so the value of the 2nd, 3rd, and 12th harmonics of a sine wave is zero.
What is meant by transformer charging?
Most likely this is referring to the initial inrush that occurs when a transformer is energized. The core of a transformer is designed for a specific magnetic field strength; When a transformer is switched into a circuit, it usually will not be switched at exactly a voltage peak. When the voltage is at its' peak, the induced magnetic field will be at zero. If the switching occurs at a voltage zero, the magnetic field strength will attempt to climb to double the designed value; since the transformer core is not generally oversized to this degree, it will saturate. This causes large inflows of current to the transformer, and shows up as even harmonics (mainly second harmonics) in the current waveform. This settles out within a few seconds (generally) to a small energizing current, usually less than 1% of the transformer's rated current.
Application of Y-delta transformations?
delta-wye is a common type of 3-phase transformer configuration. It offers a good voltage gain and the delta transformer is useful in unstable systems for removing the third harmonics. The transformation is necessary for analyzing the circuit.
