Ammeter With Improved Current Sensing
US Patent:
8212549, Jul 3, 2012
Filed:
Feb 18, 2009
Appl. No.:
12/372768
Inventors:
William J. McNulty - Washington DC, US
James S. Buchanan - Northbrook IL, US
Connor M. McNulty - Washington DC, US
James S. Buchanan - Northbrook IL, US
Connor M. McNulty - Washington DC, US
Assignee:
HD Electric Company - Waukegan IL
International Classification:
G01R 7/00
US Classification:
324141, 324117 R, 324126, 324140 R, 324127
Abstract:
An ammeter is provided with a plurality of individual wound coils interconnected in a generally U-shaped array to measure the magnitude of current in a conductor extending through a sensing region inside the U-shape. Additional pairs of position-sensing coils determine the position of the conductor relative to the sensing region and provide outputs to circuitry which permits the magnitude measurement to be displayed only if the conductor extends through the sensing region.
Voltmeter With Dual Displays
US Patent:
7746051, Jun 29, 2010
Filed:
Feb 18, 2009
Appl. No.:
12/372775
Inventors:
James S. Buchanan - Northbrook IL, US
William J. McNulty - Washington DC, US
William J. McNulty - Washington DC, US
Assignee:
HD Electric Company - Waukegan IL
International Classification:
G01R 31/02, G01R 19/00
US Classification:
324 725, 324114, 324141, 324149, 324754, 3241581, 702 62
Abstract:
A voltmeter/phaser includes dual hot-stick probes, each carrying a housing including a digital display, one of the housings also having a measurement circuit for measuring the sensed voltage. A plural-conductor cable interconnects the housings and carries, in two separate conductors, current between the probes and display data between the display circuits, so that identical voltage values are always displayed on the two displays.
