Tirril Voltage Regulator: In this type of Tirril Voltage Regulator, a fixed resistance is cut in and cut out of the exciter field circuit of the alternator. This is achieved by rapidly opening and closing…
Voltage Control Method in Power System: In a modern power system, electrical energy from the generating station is delivered to the ultimate consumers through a network of transmission and distribution. For satisfactory operation of motors,…
Three Phase Unbalanced Load: The 3-phase loads that have the same impedance and power factor in each phase are called balanced loads. The problems on balanced loads can be solved by considering one phase only…
AC Distribution Calculations: AC Distribution Calculations differ from those of d.c. distribution in the following respects : In case of d.c. system, the voltage drop is due to resistance alone. However, in a.c. system, the…
Booster Generator: A Booster Generator is a D.C. generator whose function is to inject or add certain voltage into a circuit so as to compensate the IR drop in the feeders etc. A Booster Generatorr…
Three Wire DC System Balancer Set: Although in a 3-wire d.c. system every effort is made to distribute the various loads equally on both sides of the neutral, yet it is difficult to achieve the…
Three Wire DC Distribution System: The great disadvantage of direct current for general power purposes lies in the fact that its voltage cannot readily be changed, except by the use of rotating machinery, which in…
Ring Distributor: A distributor arranged to form a closed loop and fed at one or more points is called a ring distributor. Such a distributor starts from one point, makes a loop through the area to…
DC Distribution Calculation: In addition to the methods of feeding discussed above, a DC Distribution Calculation may have concentrated loading uniform loading both concentrated and uniform loading. The concentrated loads are those which act on…
Different Types of DC Distributors: Different Types of DC Distributors - In the beginning of the electrical age, electricity was generated as a direct current and voltages were low. The resistance losses in the lines…
