Capacitance Requirements for 230kV PCBs
Capacitance Requirements for 230kV PCBs
(OP)
Hello Friends,
We have just recently reviewed 230kV SF6 power circuit breakers specification and observed that the rated Interrupting Rating of the vendor proposed power circuit breakers are less than the required S.C. value specified by BUYER. The Vendor informed us that adding some specific capacitance at suitable locations would increase the Interrupting Rating of the Power Circuit Breakers. I'm a little bit confused. Is this related to the TRV? can anyone provide me with more clear details on this subject?

Does your man mean series capacitors? That's not easily done - and I doubt that it helps. Unless they are sized to increase impedance in the transmission line, which probably is against what you want.
SF6 breakers are (slightly) better with capacitor bank switching than most other breaker types. That's the only way I can see capacitors enter the scene. But that is not what your question was about.
No. I am confused here. But prepared to learn more if someone has a good explanation.
