Design Requirements
Wireless
Stores data by day and time
Graphically display data
Visible display
More than one circuit
Expandability
TED System
4 MTUs per gateway and 2 CTs per MTU
Footprints software
Accuracy within 2%
Power Line Carrier (PLC)
Measures RMS real power
1 watt sensitivity
Display Requirements
ECE hall way Internet access Must be 2 inch depth or less No user interactions Stand by when no one is around
TED Footprints
Pros Cons
Displays power factor, complex power, and real power
Graphically displays data
Can’t switch between display modes automatically
not very fine detail No way to tell MTUs
apart or values without user interaction
Software
“It’s Electric” modified Switches between displaying by
minute, hour, day, and month Can be viewed off the Union Network Faster than Footprints and has finer
details
Electrical System Complication
Home Panel Panels in the Lab
• 2 phases and ground• 180 degrees between
each phase
• 3 phases and ground• 120 degrees between
each phase
Future Work
Software improvements Add additional sensors to the set up Change MTUs for 3 phase Incorporate the circuits in the N100
panel
