Slip Test on Synchronous Machine: Direct and quadrature axis reactances of a salient-pole synchronous machine can be estimated by means of a test known as the Slip Test on Synchronous Machine. The machine armature is…
Sinusoidally Distributed Current Sheet Concept: It was seen above that a distributed winding gives rise to a stepped mmf wave having a strong fundamental component which will be considered in machine modelling while all the…
Single Phase Two Winding Motor: Single Phase Two Winding Motor - To understand the field phenomenon that contributes towards the generation of starting torque in a single-phase motor, it greatly helps to first study a…
Single Phase Synchronous Generator: Certain applications, usually restricted to less than 10 kVA are better served by a Single Phase Synchronous Generator. Examples are emergency, domestic/office supply, portable power for construction tools etc. Because of…
Single Phase Induction Motor: A Single Phase Induction Motor comprises a single-phase distributed winding on the stator and normal squirrel-cage rotor as shown schematically in Fig. 10.1 wherein for convenience the stator winding is shown…
Single Phase Half Bridge Inverter | R Load | RL Load | RLC Load: Figure 11.46(a) gives the circuit configuration of a Single Phase Half Bridge Inverter. It has two thyristors and two free-wheeling diodes.…
Single Phase Bridge Inverter: A serious disadvantage of the half-Bridge Inverter of Fig. 11.46 is that it requires a 3-wire dc supply. This is overcome by the commonly employed Single Phase Bridge Inverter circuit of Fig.…
Shunted Armature Speed Control: Shunted Armature Speed Control - It is a variation of rheostatic control. As is obvious from Fig. 7.59, the principle used in achieving control is that of voltage division. In the…
Short Pitch Coil or Chorded Coil: Short Pitch Coil - So far it was assumed that the stator coils are full-pitched (a span of Ï€ rad elect). Coils may have a span of less than…
Short Circuit Current in Synchronous Generator: The Short Circuit Current in Synchronous Generator being electrical in nature is much faster than the electromechanical dynamics discussed already. It will, therefore, be assumed that by the time…
