It is required to connect a second transformer in parallel with the first transformer if the load exceeds the rating…
INDUCED EMF An emf is induced in the conductor either (i) dynamically or (ii) statically. In the first case, the…
Satisfactory operation of a transformer solely depends on the condition of the oil. It is required to keep the oil…
Magnetic core and windings (or coils) are the two basic parts of any transformer. The core is made of silicon…
Figure 1.15 shows sandwich windings used in shell-type transformers. The high-voltage and low-voltage windings are split into a number of…
Figure 1.9 shows spiral core-type transformer where the core is assembled either of a continuous strip of the transformer steel…
Uptill now, we have seen torque – slip characteristics of an induction motor. To compare the performance of induction motor…
Hello Engineers. 1. In an alternator, voltage drops occurs in (A) armature resistance only (B) armature resistance and leakage…
There is a specific procedure of connecting synchronous machine to infinite bus bars. Infinite bus bar is one which keeps…
In the applications where high starting torque and constant speed are desired then synchronous induction motors can be used. It…
