A plant consumes 60 kW at a power factor of 0.5 lagging from a 220-V rms 60-Hz line. Determine the value of the capacitor which when placed in parallel with the load will change the load power factor to 0.9 lagging.
Answer to relevant QuestionsA small plant has a bank of induction motors that consume 64 kW at a pf of 0.68 lagging. The 60-Hz line voltage across the motors is 220A single-phase three-wire 60-Hz circuit serves three loads, as shown in Fig P9.64.
