A three-phase, wye-connected, cylindrical-rotor synchronous generator rated at 10 kVA and 230 V has a synchronous reactance of 1.5per phase and an armature resistance of 0.5 per phase.
(a) Determine the voltage regulation at full load with: (i) 0.8 lagging power factor, and (ii) 0.8 leading power factor.
(b) Calculate the power factor forwhich the voltage regulation becomes zero on full load.
3) The impedance for a 120 km, 230-kV line is given as j 0.9 ohm/km and j 0.6 ohm/km for self and mutual terms respectively; resistance is neglected. The mho characteristic for the
(a) contains a freewheeling diode Dm, commonly connected across an inductive load to provide a path for the current in the inductive load when the switch S is opened after time t (
Q. Show Benefits of digital systems? Ever since most digital systems have only two possible states, there is high degree of accuracy in the transmission of data. With an analog
Q. Explain braking mode of rotating machines? The braking mode has both mechanical and electric energy input. The total input is dissipated as heat. The machine is driven by th
