Question

An industrial customer is fined if the power factor of the plant falls below 0.85. The equivalent loads of the plant are: 30 lamps of 400 W, an Electric Oven with an impedance of (2.4 + j3.2)  and a load of 80 kW due to an engine block. The three charges are in parallel. Induction motors have a power factor of 0.8 and a performance of 0.98. The customer has a 600V, 60Hz supply.

a) Calculate the average power and total reactive power.
b) Size the necessary condenser that is required so that the client is not fined.
c) As a consequence of installing the capacitor calculated in b), say if the network is released with respect to the total load. In how many amps is the network released?
