Function Generator setup: Uncompensated power factor: Time shift = 65 μ s Phase shift = 65 μ s × 2500Hz × 360 ° = 59 ° pf = cos(59 ° ) = 0.52 lagging
Compensated power factor: Time shift = 30 μ s Phase shift = 30

Unformatted text preview: s 2500Hz 360 = 27 pf = cos(27 ) = 0.89 lagging Further Exploration: Without power factor compensation: Load voltage: 603 mVrms Load current: 151 mArms With power factor compensation: Load voltage: 609 mVrms Load current: 99 mArms The load voltage remains the same while the load current drops to 65% of the original value, a significant reduction that suggests reduced resistive losses in power transmission....
