Proximity Effect : Working, Affecting Factors, Differences, Advantages, Disadvantages & Its Applications

September 9, 2024 By Wat Electrical

Proximity Effect

Understanding & mitigating the proximity effect is significant in the electrical system design & operation which uses high-frequency AC. The strength of this effect can be influenced by the conductor's structure, diameter & material. The impact of this effect can be reduced by right conductor spacing and geometric arrangement and also decrease power loss, its detrimental effects on resistance & performance of inductor. It is achievable to … [Read more...]

Transmission Lines : Parameters, Types, Efficiency & Characteristic Impedance

Transmission Lines

The first transmission line was demonstrated over an extended distance by physicist Stephen Gray on July 14, 1729, to show that one can transfer electricity through that method. This demonstration is used damp hemp cords which are balanced through silk threads. In 1882, electric power transmission was accomplished by the first high-voltage transmission between Munich & Miesbach. After that in 1891, the first three-phase AC overhead line construction … [Read more...]

What is Ferranti Effect : Circuit Diagram, Advantages & Disadvantages

January 31, 2020 By Wat Electrical

ferranti-effect

Ferranti Effect is one of the undesirable phenomena that happens in power systems. Fundamentally it explains the rise in receiving end voltage as compared to sending end voltage due to line capacitance and inductance for a long transmission line i.e. the transmission line with length greater than 160 km. Conceptualized by Sir S. Z. Ferranti in the year 1887, this effect explained the impact of line capacitance on receiving end voltage under no load or … [Read more...]
