RE MEASURING CURRENT - "BOYD S.(SPENCE) MINER" - Apr 22 11:55:26 2007
EXCUSE THE CAPS. MUCH EASIER FOR ME.
A VERY BIG CAUTION!!!!!!!!!!!!!!!!!!!!!!
IF YOU USE A CURRENT TRANSFORMER OR TOROIDAL TRANSFORMER, BE SURE TO HAVE A
RESISTIVE LOAD ON THE SECONDARY AT ALL TIMES. WITHOUT IT, YOU HAVE THE
POSSIBILITY OF EXTREME HIGH VOLTAGE...................
CAN EVEN CAUSE ARCING TO OTHER COMPONENTS.

Re: RE MEASURING CURRENT - p_dubinsky - Apr 22 16:32:18 2007
Thanks for the heads up, Spence. (And don't woory about the CAPS -
we're all headed there.)
And thanks to all for the suggestions. I've order a CR Magnetics
device to play with. I'll let you know how it goes.
Thx again,
Paul
