What is Hysteresis Loop? Its Importance
A hysteresis loop is a graph in a four-quadrant that shows the relationship between the induced magnetic flux density B and the magnetizing force H.

The differential relay is used for the protection of the transformer, alternator, and large-rating HT motor. The differential protection scheme is also known as zone
The transformer transforms voltage from one level to another without changing the power and frequency. The transformer is static electrical equipment, and it does not
The adverse Effects of Harmonics on Capacitors comprise series and parallel resonance, heating, overloading, and increased dielectric loss. The harmonics also cause a severe problem of
What is an Ideal Transformer? An ideal transformer is free from all losses. It has zero copper and iron loss and zero leakage flux, and
Power cables carry power from the supply source to the load point. They have DC resistance, which depends on their size. When current flows through
The HV and LV winding is wound around the central limb. The central limb carries the entire flux (Ф ). The flux (Ф ) divides into two equal part and thus each side limbs carries the half (Ф/2 ) of the total flux(Ф ). As a result, cross section area of the central limb is two times of the side limbs area.The arrangement of the winding around the central limb is as given below.
The maximum current a transformer can deliver to loads at the rated voltage is known as a transformer rating. It is expressed in VA, kVA,
What is the Voltage Regulation of a Transformer? Voltage regulation of the transformer is defined as the percentage change in the transformer’s secondary voltage from
When two single-phase transformer is connected in an open delta connection, the arrangement can provide a three-phase supply to the load. The open delta connection
