Three Phase Unbalanced Load

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 ; the conditions in the other two phases being similar. However, we may come across a situation when loads are …

AC Distribution Calculations

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 voltage drops are due to the combined effects of resistance, inductance and capacitance. In a d.c. system, additions and subtractions …
