As shown in Fig. 11.85, a 550-V feeder line supplies an industrial plant consisting of a motor drawing 60 kW at 0.75 pf (inductive), a capacitor with a rating of 20 kVAR, and lighting drawing 20 kW.
(a) Calculate the total reactive power and apparent power absorbed by the plant.
(b) Determine the overall pf.
(c) Find the current in the feeder line.
Design a circuit that will check if a two digits decimal number is equal to a set ofpredefined number. If they are the same, then allow a door to be unlocked. Else, the doorwill stay locked. Can anyone give me some idea on this topic?
