Three Phase Power Factor Corrections And Three Phase Current Balance For Electrical Power Distribution Systems

Abstract

147 Any lead or lag in current with respect to the applied voltage is called a power factor loss and depends upon the degree of lead or lag. Since the power is distributed as an Alternating Current ( AC) in a sine wave form, this lead or lag can be measured as an angle with respect to some time zero and both the current and voltage can be shown as related to each other by this angle ( hence the term phase angle ).
