Algorithm for Short Circuit Computation: So far we have carried out short circuit calculations for simple systems whose passive networks can be easily reduced. In this section we extend our…
Basic Principle of Chopper Circuit: A Basic Principle of Chopper Circuit is essentially a thyristor switch in series with the load as shown in Fig. 11.27(a). A shunting diode is…
What is Silicon Controlled Rectifier (SCR)? | Construction and Working of SCR: What is Silicon Controlled Rectifier (SCR)? - This semiconductor switching device is also known as a thyristor. It…
Isolated Induction Generator: An Induction Machine can also work as a generator even if external power supply not available and it is called Isolated Induction Generator. An Isolated Induction Generator…
Induction Generator Transmission Line Diagram: An induction generator is asynchronous in nature because of which it is commonly used as windmill generator as a windmill runs at non-fixed speed. These…
Hopkinsons Test on DC Machine: This is a regenerative test in which two identical dc shunt machines are coupled mechanically and tested simultaneously. One of the machines is made to…
Characteristics of Separately Excited DC Generator: With the advent of silicon-controlled rectifiers, the importance of the dc machine as a generator has considerably reduced as SCRs can be employed to…
Methods of Excitation of DC Generator: The performance characteristics of a dc machine are greatly influenced by the way in which the field winding is excited with direct current. There…
