If you are searching information regarding electric current then you have come to the right place. For more details visit us, we’re here to help you.
A voltage regulator is used to regulate or stabilize the voltage level for specific purpose. Voltage fluctuations are never acceptable for any appliance or equipment, because it may damage the electrical appliances etc. When a steady, reliable voltage is needed, then voltage
What is overvoltage: A sudden rise in voltage for a short duration on the power system is known as overvoltage or voltage surge. Overvoltage is always temporary that exist for short period but that may cause damage to the power system due
The phenomena of levitation of a magnet above a cooled superconductor is known as the Meissner Effect. If a superconductor is cooled below its critical temperature while in a magnetic field, the magnetic field surrounds but does not penetrate the superconductor. The magnet
superconductor definition Before understanding the superconductor lets see what is superconductivity, it is the flow of electric current without resistance in certain metals, alloys, and ceramics at temperatures near absolute zero, and in some cases at temperatures hundreds of degrees above absolute
As a standard practice installer or contractor shall arrange for the witnessing of the following tests on the fully equipped switchboards (main, submain distribution boards and Motor Control Centers MCC) including primary bus bars and connections at the factory, in accordance with
Cable sizing is done based on three parameters: Load current, Short circuit current carrying capacity, Voltage drop. Below are given simple steps for performing cable sizing calculations. Step 1 – Calculate Load Current: Calculate the load current from the load data available.
