Explain Synchronous Generators?
They can be utilized to produce or absorb reactive power. An over-excited machine produces reactive power when an under-excited machine absorbs it. The generator is the major source of supply to the system of both of the positive and negative VArs. The ability to supply VArs is ascertained by the short-circuit ratio (1/ synchronous reactance).
For economic reasons, in current units this ratio is kept low and therefore the inherent ability to run at leading power factors is not large. For instance, a 200 MW, 0.85 p.f. machine with a 10% stability margin can just supply 45 MVAr at full power outputs.
Chopper Configuration Chopper are classified in five different classes according to their operating capability in particular quadrant. The current directions and voltage
Trap is called as Non-Maskable interrupts, which is used in emergency condition.
The mechanical power produced at the armature of a motor is: P = T a . (power is in watts if torque is N.m and in rad/sec). Some of this will be lost due to friction and
Q. Can you explain twos Complement Division? 2's complement division is repeated 2's complement subtraction. The 2's complement of the divisor is calculated, and then added to
