The load on a given station consists of 2,000 KVA at 0.866pf inductive. Two alternators each of 1,500 KVA capacity furnish the energy and are operated so that the ammeter readings of the two alternators are equal. Alternator A furnishing energy at unity pf and Alternator B furnishing the remainder of the current. Determine the KVA output of the Alternator B. Note that alternators operating in parallel have the same apparent powers
