Lightning and Switching Voltage Protection Methods

Most insulations fail during one of the following events: Switching overvoltage due to the inductive and capacitive energy of the system overshooting the system voltage that can be as high as 2 × rated voltage. This is analogous to overpressure due to water hammer when a water pipe is suddenly shut off (switched-off). Lightning overvoltage …

Kirchhoff’s Current Law Examples

The Kirchhoff’s Laws are very useful in solving electrical networks which may not be easily solved by Ohm’s Law. In this article, I will describe the Kirchhoff’s current law and will show some kirchhoff’s current law examples to make this law easily understandable. Kirchhoff’s current law states the following: The summation of currents entering a node …
