Q. Athree-phase, 60-Hz substation bus supplies two wye-connected loads that are connected in parallel through a three-phase feeder that has a per phase impedance of 0.5 + j2 . Load 1 draws 50 kW at 0.866 lagging PF, and load 2 draws 36 kVA at 0.9 leading PF. If the line-to-line voltage at the load terminals is 460 V, find the following:
(a) Total line current flowing through the feeder.
(b) Per-phase impedance of each load.
(c) Line-to-line voltage at the substation bus.
(d) Total real and reactive power delivered by the bus.
a) What is meant by Ripple Voltage? Measure the Ripple Voltage Amplitude, Frequency and DC Offset b) Describe how Ripple Voltage could be decreased.
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
Q. An operational amplifier stage is typically represented by the circuit of Figure. For the values given, determine V out and the power supplied by the 2.5-V source.
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
Q. A balanced delta-connected load with a per-phase impedance of 12 + j9 is supplied by a 173-V, 60-Hz three-phase source. (a) Determine the line current, the power factor, th
trigger capabilities of logic analyser that differentiate it from other devices???
A 440-V, 60-Hz, six-pole, wye-connected, squirrel-cage induction motor with a full-load speed of 1170 r/min has the following parameters per phase referred to the stator: R 1 = 0.
