Tim Your geography of the south needs further study - Chalfont is hardly on the direct line between Luton and Bromley (but my office is!)

However if I'm passing near to Chalfont I'll be in touch.

Charles

Ok, Ill drop it off with Peter as arranged on Boxing Day.

Dave

Sorry Charles, I didn't mean to suggest it was. I was just 'throwing that in' in case anyone was passing that way who could get it 'into the system'.

Thanks

I thought I was being quite restrained really 8-), lets face it there are some here who think they can invent their own physics and argue themselves into being right!. Asking questions and trying to understand the answers is healthy and to be encouraged, but yer canna rewrite the laws o physics 8-)

I thought I'd let this run a while before I put my two-pennyworth in. Gents; we must remember that RMS in the conventional sense is measuring a sinusoidal waveform. A half-wave rectified sinusoid is anything but sinusoidal. Its full of harmonics which all contribute. Nobody who understands what's really going on would suggest the RMS of a square-wave is root 2 x peak.

Charles / Dave / Peter that would be excellent - many thanks

Ah, the killfile is a wonderful invention... :-))

I should be that way sometime in January though.....

Charles

Yup, and if you wrote to Smithy with an idea, they paid either 10/6 or a guinea if published. Money for old rope. Made a few bob that way. .

Boxing Day anyway!

Dave met us at Kettering this morning and a suitably impressive toroidal tranny was transferred to our custody.

If Charles can let us know when he is next near to Luton, we can get him to collect it for onward transportation.

toroidal tranny

Many thanks to Dave and Peter, I look forward to installing it !

AWEM

I'll be in touch next Tuesday when I'm back in rhythm with the workaday world.

Charles

Thanks Charles - I'll put the kettle on!

AWEM

It's at the factory now, in the office in a cardboard box, just in case I am not there when you call.

And if you find any of those errant spot welder trannies......

Utter rubbish!, RMS is all about measuring ANY repetitive waveform.

And as such RMS is an ideal way to measure it.

I wonder where you think square waves come into this... Greg

Dave, Charles, Peter, and all others who contributed many thanks.

Charles has dropped off the transformer and it looks splendid

Regards,

AWEM
