Solve this question
A group of induction motors with a total of 500 kW and a power factor of 08 lagging is to be partially
replaced with synchronous motors of the same efficiency but leading power factor of 0 707. As the
replacement programme continues, the overa!! power factor is constantly improving. What percentage
of the load will have been replaced when the system power factor reaches 09 lagging?
