MGVCL Exam Paper (30-07-2021 Shift 2)
A delta-connected balanced three-phase load is supplied from a three-phase, 400 V supply. The line current is 20 A and the power taken by the load is 10 kW. Find the power factor.
A term brown out means it is an intentional or unintentional drop in voltage in an electrical power supply system. Brown outs are long-term (hours-long) voltage sags caused by system overload. Deviations from the regular sinusoidal wave, both on the utility side and on the customer side, result in poor power quality.
