Hint: A transformer is a device that is used from one circuit to another to transfer electrical energy. Its operation is based on the reciprocal induction of two coils placed near each other. Voltage distortion increases losses due to hysteresis and eddy currents and causes the insulation material used to over-stress. The primary effect of transformer power line harmonics is, hence, the additional heat generated.
Complete answer:
1.Transformers: Transformer harmonics cause an increase in the loss of iron and copper. Voltage distortion increases losses due to hysteresis and eddy currents and causes the insulation material used to over-stress.
2.The primary effect of transformer power line harmonics is, hence, the additional heat generated. What Will Harmonics Cause.
3.Harmonics are produced by electronic devices with nonlinear loads drawing in abrupt short pulses in the current.
4.Distorted current waveforms are caused by short pulses, which in turn cause harmonic currents to flow back into other parts of the power system.
5.More than 100 percent of the fundamental 60 Hz can be the amount of harmonic current drawn by a computer.
5.These 'triplen' harmonics, which are multiples of three, are additive and do not cancel in the common neutral.
6.Transformer theory demonstrates that a delta winding can not pass out of balanced triple harmonic currents.
Note:
In a transformer, we use a laminated steel core because it reduces losses caused by eddy currents. Due to changing magnetic fields around it, Eddy currents are currents that are set up in a conductor. They are not beneficial and lead to energy loss.
