Corona Effect in Transmission Lines & Power System

A Full Guide about Corona Effect - Corona Discharge in Transmission Lines

A Full Guide about Corona Effect – Corona Discharge in Transmission Lines What is Corona or Corona Discharge? When an alternating potential difference is applied across two conductors whose spacing is large as compared to their diameters, there is no apparent change in the condition of atmospheric air surrounding the wires if the applied voltage is low. However, when the …

Introduction to Harmonics – Effect of Harmonics on Power System

Introduction to Harmonics

What are Harmonics and How to Filter and Eliminate it. (Manuel Bolotinha) Introduction to Harmonics The quality of electrical power supply is an important issue both for utility companies and users, but that quality may affected by electromagnetic disturbances. Among these disturbances it must be highlighted harmonics that happens in all voltage levels and whose study, calculation of acceptable values …

Short Circuit Currents And Symmetrical Components

Short Circuit Currents faults And Symmetrical Components

Short Circuit Currents And Symmetrical Components (Manuel Bolotinha) Short Circuit Faults and Currents Short-circuits can occur phase-to-phase and phase-to-earth, mainly due to: Dielectric breakdown of insulating materials (ageing, severe overheating and overvoltages, mechanical stress and chemical corrosion are the main factors for dielectric breakdown) Decrease of creepage distance (the shortest path between two conductive parts – or between a conductive …

What is the Difference Between Neutral, Ground and Earth?

What is the Difference Between Neutral, Ground and Earth

The Main difference between Neutral, Ground and Earth? ‪To understand the difference between Neutral, Ground and Earth, we must understand the need of these things first. Neutral Neutral is return path for an AC circuit which is supposed to carry current in normal condition. This current may be because of many reasons, primarily because of phase current imbalance and some …

The Main Difference between Linear and Nonlinear Circuit

Difference between Linear and Nonlinear Circuit

The Main Difference between Linear and Nonlinear Circuit Linear Circuit In simple words, a linear circuit is an electric circuit in which circuit parameters (Resistance, inductance, capacitance, waveform, frequency etc) are constant. In other words, a circuit whose parameters are not changed with respect to Current and Voltage is called Linear Circuit. Fundamentally, the word “linear” literally means “along with …
