Yes, I calculate capacitance from capacitor rated. In Delta loop had Cx, Cy and Cz, So when we measure at terminal AB, Cab = Cx // (Cy + Cz) at 50 kVAR 400V Cab = 497.36 uF

When we change new power capacitor (PF Improvement)? Ex. Cap 50 kVAR 400V Ir = 72.2 A Cab = 497.36 uF(Delta connection) In catalogue shown -5% to +10% (Tolerance 472.5 - 547.1 uF) - Why new cap have Capacitance more than calculated value? Ex Ccal = 497.36 uF Cnew = 570 uF(more than 10%)...

So, how about loss of all MV tuned filters? Normal or Abnormal. Thank

We measured Active, Reactive and Apparent power of tuned filters. 6.6 kV system. Indoor, Aircore reactor, Cable length < 35 meters. 1. 5th Filter#1 3.9 MVAR(Design) P = 54 kW Q = 4.19 MVAR I = 365 A THDi < 5%(Measured) 2. 7th and 11th Filter#1 7.8 MVAR(Design) P = 159 kW...
