PF stands for Power Factor, which is the ratio of real power to apparent power in an electrical system.

• Power Factor is a measure of how efficiently electrical power is being used in a system.

• It is expressed as a decimal or a percentage, with a value of 1 or 100% indicating perfect efficiency.

• A low power factor can result in increased energy costs and reduced equipment lifespan.

• Capacitors can be used to improve power fa...read more

Star and Delta connections are used in three-phase AC systems to control voltage and current.

• Star connection is used when the load requires a lower voltage than the supply voltage.

• Delta connection is used when the load requires the same voltage as the supply voltage.

• Practically, star connection is achieved by connecting the three phases to a common point and the load to the other ends of the phases.

• Delta connection is ...read more
