Answer Posted / venkatesh o
normally Formula
Kvar= 1.732*V*I*Sin(pi)
If Pure Capacitor 90 Leads so The power factor is Unity(1)
Assume *V=415
*Sin(90)=1(But Reactive power is zero)
since I=Kvar/1.732*V*1 Eg. 1000/1.732*415*1=1.39A
other formula for Determine KW=KVAR/tan(pi)or KW=VIcos(PI)
Assume * cos(0.9)
since KW=KVAR/tan....Equ 1, take the cos invesr is equal to (0.9)=25.8419 ...Equ 2
KW=30KVAR/tan25.8419=61.94KW OR
they are more formulas
* KW=KVAR/tan(pi)
* Kw=KVA*cos(pi)
* Kw=SQroot(KVAZ^2-(KVAr)^2

In Power Line Communication (PLC) the wave trap is used to block communication signals from entering neighboring lines. My question is this: Why do they allow for different filtering arrangements on these wave traps? Isn't it always going to be a low pass filter since we want the power frequency to go through, and the comm signal blocked?
