Single Phase AC Circuits

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 …

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 (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 …

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 …

Resistance The property of a substance or material which oppose the flow of electricity through it is called resistance OR, Resistance is the ability of a circuit or element (which is called resistor) to oppose current. Examples of Resistors with the ability of high resistance are Wood, Air, Mica, Glass, Rubber, Tungsten etc. Unit of Resistance is “Ohm” and it is …

Electric Circuit, Network, Complex Circuits and other Types of Circuits What is an Electrical Network? Combination of different electric elements or components which are connected in any way is called electric network Complex Networks A Circuit which contains on many electrical elements such as resistors, capacitors, inductors, current sources and Voltage source (both AC and DC) is called Complex network. …

What is Node, Branch, Loop & Mesh in Electric Circuit? Solving and analyzing electrical circuits and networks, we must know about Nodes, Branches, Loops, and Meshes in an electric circuit and network. First, we have to know about Node, Branch, Loop and Mesh and their role in an electrical circuit. We may determine the exact number of branches, nodes, loops, …

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 …
