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 … Read more
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 … Read more
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 … Read more
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 … Read more
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, … Read more
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 … Read more
