Explain Overhead Lines and Transformers?
Overhead lines absorb reactive power when fully loaded. A line with a current I A, a line reactance of XL ?/phase absorbs I2 XL VArs/phase. On light loads, the shunt capacitance of a long line may become predominant and the line becomes VAr generator producing V2 /XC VArs/phase. Transformers always absorb reactive power.
Describe the effect of following parameters on working rate and accuracy of material removal in AJM. (i) Grain size (ii) Stand off distance (iii) Jet velocity. Draw sch
Q. A 50-kW, 250-V, short-shunt compound generator has the following data: R a = 0.06 , R S = 0.04 , and R f = 125 . Calculate the induced armature voltage at rated load and t
Interrupt latency refers to the amount of time among when an interrupt is triggered and when the interrupt is observe by software.
