Band Stop Filter

Band Stop Filter: Band Stop Filter stop a range of frequencies between two cut-off frequencies f1 and f2 while pass all the frequencies below f1 and above f2. Thus range…

Band Pass Filter

Band Pass Filter: Band pass filter pass a certain range of frequencies (called as pass band) while attenuate all other frequencies. Such band pass filters can be obtained by connecting…

Driving Point Immittance Function

Driving Point Immittance Function: The immitance function must be positive real function so that its synthesis can be done to obtain an electrical network, using passive elements. We have discussed…

Linear Resistance Damping

Linear Resistance Damping: By introducing a linear resistance across the circuit breaker during interruption, the restriking transients are damped. Provision has to be made for subsequent interruption of the resistance…

Current Chopping

Current Chopping: When interrupting small inductive currents such as transformer excitation currents, circuit breakers tend to clear before the natural current zero is reached. This is because the low-current ionized…
