Differential busbar protection is the most common and reliable scheme for the bus bar protection. Earlier there was no other option to use only conventional over current relays for busbar protection. But it is desirable that fault in any feeder or transformer connected to the busbar system should not disturb overall busbar system. Due to… Read More: Electrical Busbar Protection – Differential Relay Function »
Kirchhoff’s Voltage Law states that net voltage gain and net voltage drops along a closed loop are equal. Kirchhoff’s Current Law states that at any point in the circuit the total current enters, is exactly equal to the total current leaves the point. There are some simple relationships between currents and voltages of different branches of an… Read More: Kirchhoff’s Rules Kirchhoff’s Voltage Law – Kirchhoff’s Current Law »
In order to understand the usage of different types of capacitors in transmission lines we must first look in different way first the effect of power factor on the power system. Because the subject is related to the power factor correction. The power factor formula of an AC electric power system clearly indicates that this… Read More: Series and Shunt Capacitors in Transmission Lines for Power Factor… »
Both short circuit and open circuit tests are conducted to measure the core and winding losses of transformers. As we know that there are mainly two major parts of transformers i.e. core and winding, which are made of two type of materials, which are iron and copper. The core of a transformer is made of… Read More: How to Measures Core and Winding Losses of Electrical Current… »
This page is dedicated for providing best and up to date information about the coulomb’s law. In addition you can find the definition, equation and formula for understanding the basic concept of coulomb’s law. You already know that when two charged bodies come closer there is always a force of attraction or force of repulsion. What is… Read More: Coulomb’s law Definition Equation & Formula »
Conductivity refers to the ability to conduct, convey or pass through, and in case of electricity it refers to ability to convey the electric current. On the other hand for thermal conductivity it is the ability to conduct or pass the heat for any material. Similarly if we talk about the reverse side of conductivity… Read More: Electrical & Thermal Conductivity and Wiedemann Franz Law »
