Unbalanced Loading Protection of Generator: Unbalanced Loading Protection of Generator - Whatever be the cause of the unbalance it is obvious that the negative phase sequence current will result in…
Phase Comparison Carrier Protection: The phase comparison pilot-relaying operates on the principle of comparing the phase position of the currents at the two ends of the protected section. The Phase…
Derivation of Single Phase Quantity from Three Phase System: It will be seen later that auxiliary channels or pilot wires are used to transmit information from one end of the…
Unbalanced Rotor Impedance Operation: Earlier Unbalanced Rotor Impedance Operation were employed for starting and speed control. They are not in use any more. However, a loose contact in the rotor…
Unbalanced Source Voltages Operations: As Supply voltage may sometimes become unbalanced, it is useful to know the effect of Unbalanced Source Voltages Operations on motor performance. Further, motor terminal voltage…
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…
Inductance of Three Phase Line with Unsymmetrical Spacing: The basic equations developed can, however, be easily adapted to the calculation of the Inductance of three phase line. Figure 2.10 shows…
Equivalent Circuit of Single Phase Induction Motor: Equivalent Circuit of Single Phase Induction Motor - The winding unbalance and the fact that both the main and auxiliary windings are fed…
