Hi Dmitry,

Thanks for straightening this out.
I warned you against my bad russian o:)

BTW,if the 'erected capacitance' is what I think it
is,than you have answered my inital question
concerning energy storage capacity of the bank.

50nF @ 5MV - Wow!That makes at least 625 kJ to play
with.

Kind regards,
Boris
