Learn Electrical Engineering
Learn about lightning arresters — types, construction, working, and testing methods that protect power systems from surge and overvoltage damage.
An attraction type moving iron instrument works based on the principle of attraction of a magnetic material towards the coil. Basic Structure Suppose there is a coil. We connect this coil with an electric source. Whenever we inject current into the coil, the coil will become a magnet. Obviously, this magnet attracts any iron pieces … Read more
An LCR meter is an advanced measuring instrument. We use it to measure the inductance (L), capacitance (C), and resistance (R) of a circuit. It helps determine the precise values of capacitances, inductances and resistances. These are the three basic parameters of an electrical or electronics circuit. It can measure the three circuit parameters: inductance … Read more
