Answer / manish kumar meena

here you are saying about parallel operation,in parallel
operation conditions ae that
1) frequency should be same.
2)operating voltage must be same.
3) phase sequence must be same.
so these factors must be considered,in second part if VAR
flow is less then you have good power factor,and if VAR
flow is more then you have not that much good power factor.
