Provides an original, detailed and practical description of current interruption transients, origins, and the circuits involved, and how they can be calculated Current Interruption Transients Calculationis a comprehensive resource for the understanding, calculation and analysis of the transient recovery voltages (TRVs) and related re-ignition or re-striking transients associated with fault current interruption and the switching of inductive and capacitive load currents in circuits

Clear explanation on how to calculate transients, showing how four basic circuits can represent all transients and can be solved in general without any use of the classical Laplace transform method

Fault current interruption and inductive and capacitive load current switching cases illustrated using real application examples

It will also be useful for senior undergraduate and postgraduate electrical power engineering students looking to work in switchgear manufacturers and testing laboratories.

It will be of great interest to practicing engineers and electric utility staff involved in circuit breaker design, specification, testing, switchgear application, system operation and planning, and in particular, for engineers using simulation programs for transient calculations

Key features Detailed theory on all of the current interruption cases that can occur on a power system

Series and parallel RLC circuit theory, followed by the calculation of pole factors using the symmetrical component method to derive the base power frequency components, with results applied to all the relevant transient cases

This book provides an original, detailed and practical description of current interruption transients, origins, and the circuits involved, and how they can be calculated and then analysed using only a hand calculator and a spreadsheet program

With its practical approach, this book offers engineers the tools they need when analysing circuit breaker applications
