Sincerely,        >                     I’m thinking about my $25 E, H signal level meter but it’s only 10kHz to       3GHz and measures in V/m and uT/m              Using a dipole antenna loaded with an LC filter tuned to swamp any RF above       10kHz and a large loop antenna with the same, I think it’s possible to       measure power factor remotely then aggregate the field measurements to compare       with the power studies to        determine which load networks will benefit from a low Q Cap loading on a       transmission line modelled on Falstad’s with a delay line network simulation.              AC motors usually draw a bit more than 5 times the rated load current on start       up which when unloaded means it’s about 50 times with zero load , so       effectively it’s 98% VAR, or 2% of then determine the cyclical nature of       motor work during the day and        the distribution of loads from steady, variable , start-stop, arc welding ,       old fashioned HPS street lamps and determine which of loads will save on       maintenance costs with some sort of threshold model.              The best tools are the one you know how to use and you will wish you knew MB       Hydro’s PSTools (?). It I know Falstad’s web simulator really well is       capable of good simulations on transmission lines in time or spectral domain.              Anyways if there was a PO, I could design my idea for a non-contact EH PF       tester.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
