Graph Theory Network Analysis: To analyse a network means to find current through any branch or voltage across any branch. We can analyse given network using Graph Theory Network Analysis by relating branch currents and…
Grading of Cables: The process of achieving uniform electrostatic stress in the dielectric of cables is known as grading of cables. It has already been shown that electrostatic stress in a single core cable has…
Geothermal Power Plant Working Principle: Geothermal Power Plant Working Principle - The growing demand of power will exhaust all fossil fuel sources in few decades. Therefore there is a permanent need for unconventional energy sources…
Generator Transformer Protection: Generator Transformer Protection - Protective relays, being component parts of electrical switchgear, should be closely associated with the control section of such systems, e.g. indicating and signalling systems. Thus the signalling and indicating systems must also be designed on…
Generator Rotor Field Suppression and Neutral Circuit Breaker: In the event of a fault on a generator winding even though the generator circuit breaker is tripped, the fault continues to be fed as long as…
Generator Inter Turn Fault Protection: Merz-Price circulating current protection system does not provide protection against turn-to-turn faults (short circuits between the turns) on the same phase winding of the stator because the current produced by…
Generator Faults: Generator faults can be considered under the following heads. (a) Stator Faults: These include the following: Phase-to-earth faults. Phase-to-phase faults. Inter-turn faults. Most faults occur in the stator windings and their connections and…
Generation of Three Phase Voltage: Three Phase Voltage can be generated in a stationary armature with a rotating field structure, or in a rotating armature with a stationary field as shown in Fig. 9.2 (a…
Generation of Switching Surges: Nowadays in extra high voltage transmission lines and power systems, switching surges is an important factor that affects the design of insulation. All transmission lines rated for 220 kV and above…
Generation of Impulse Current Generator Output Waveform: Lightning discharges involve both high voltage impulses and high current impulses on transmission lines. Protective gear like surge diverters have to discharge the lightning currents without damage. Therefore,…
