Problem 3: Figure shows a residential secondary distribution system. Assume that the distribution transformer capacity is 70 kVA with Zz = 0.025 + j 0.035 p.u. , all secondaries and services are single-phase three wire, nominally 120/240 V, all SLs are of #270 (k=0.028 Per unit voltage drop per 104 A.ft), and SDs are of #1/0 (k=0,017 Per unit voltage drop per 10* Aft) All SDs are 100 ft long, and all SLS are 200 ft long. Assume an average lagging-load power factor of 0.9 and Coincidence factor = 0,8 SEVA EVA SVA SEVA GEVA AVA BE SI SL EVA VA IVA VA TOLVA Determine the following a. Find the total load on the transformer in KVA and in per units. b. Transformer voltage drop. C remote mort Find the total steady-state voltage drop in per units at the and severe customer's meter for the given annual maximum system loads.
