Rogowski Coil Integrator Design: If a Rogowski Coil Integrator Design is placed surrounding a current carrying conductor, the voltage signal induced in the coil is vi(t) = M dI(t)/dt where…
Measurement of High Direct Current: High magnitude direct currents are measured using a resistive shunt of low ohmic value. The voltage drop across the resistance is measured with a millivoltmeter.…
Van De Graaff Generator Working Principle: The schematic diagram of a Van De Graaff Generator Working Principle is shown in Fig. 6.6. The generator is usually enclosed in an earthed…
Applications of Power Transformers: Transformers are the first to encounter lightning and other high voltage surges. The transformer insulation has to withstand very high impulse voltages many times the power…
Breakdown in Composite Dielectrics: It is difficult to imagine a complete insulation system in an electrical equipment which does not consist of more than one type of insulation. If an…
Busbar Arrangements in Substations: Busbar are the important components in a sub-station. There are several Busbar Arrangements in Substations that can be used in a sub-station. The choice of a…
Types of Surge Absorber: The travelling waves set up on the transmission lines by the surges may reach the terminals apparatus and cause damage to it. The amount of damage…
Surge Diverter | Lightning Arrester Types: The earthing screen and ground wires can well protect the electrical system against direct lightning strokes but they fail to provide protection against travelling…
