When the two-wattmeter method for measuring three-phase power is used on a certain balanced load, readings of 1200 W and 400 W are obtained (without any reversals). Determine the delta connected load impedances if the system voltage is 440 V. With the information given, is it possible to find whether the load impedance is capacitive or inductive in nature?
