What is the technical definition of Power Factor (PF)?
• Power Factor consists of three components: KW, which is the working, or real, power; KVA, which called the apparent power; and KVAR, or reactive power. KW does the actual work, whereas KVAR does not do any beneficial work. The measurement of the relationship between KW and KVAR is the KVA. Reactive power is measured in volt-amperes reactive (VAR), also known as KVAR when the number exceeds1,000.
