Filter Fundamentals in Network Analysis: Filter Fundamentals in Network Analysis - The complete study of behavior of any filter section needs calculations of its characteristic impedance (Z0), propagation constant (γ),…
LC Immittance Function: The LC Immittance Function can be LC impedance functions denoted as ZLC(s) or LC admittance functions denoted as YLC(s). A LC network does not contain power dissipative…
Loop Matrix or Circuit Matrix: For a given directed graph, it is always possible to state which branches are involved in the formation of loops or closed circuits or meshes.…
Laplace Transform of Impulse Function: The Laplace Transform of Impulse Function is a function which exists only at t = 0 and is zero, elsewhere. The impulse function is also…
Basic Components of Static Relays Articles Semiconductor Diodes in Static Relays: The pn junction has rectifying characteristics as shown in Fig. (10.1). If a source of emf is connected to…
SF6 circuit breaker: One of the recent developments in the field of high voltage switchgear is the SF6 circuit breaker. In this a gas called sulphur hexafluoride is used as…
Vacuum Circuit Breaker: Although the advantages of interrupting the arc in a vacuum were recognized as early as the nineteenth century, this did not find wide application till a few…
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…
