ctpt= current transformer & potential transformer

CT connected in series with the circuit & pt connected in
parallel to trivector meter

trivector meter is metering device which reads all
parameter of electrical devices like
KW,KVA,KVAR,KVARH,PF,I,V,etc

present we are having 0.8pf but I want increase it up to 0.99 so what is the formula for it and how can i calculate?
