Solkor summation transformer component 2

[SolkorSte]

Can anyone tell me the purpose of the capactitor in the drawing of a Reyrolle SOLKOR A summation transformer below

I think the cap is provided in order to reduce the reaction time of the pilot wire by decreasing the reactance. [Time=k*X/R]

It's part of a tuned circuit designed to give a peak response at the power system's fundamental frequency and suppress response at harmonic frequencies. There's some explanatory notes in the IEE book "Power System Protection Systems & Methods" - luckily Google has it as a preview to save you buying it! Here's the Link.


If David Beach happens to be reading this, this is a book which is worth adding to the FAQ.

If we learn from our mistakes I'm getting a great education!

Scotty, Things are a bit hectic at the moment. If you could send me a reminder through the FAQ comment I would appreciate it. Thanks.

Thank you, Scotty. From the "link" it is clear that is a pass-high filter.
