I recently installed a TED Pro system on 240V split single-phase 3-wire electrical system at my home.
2 CT's (plugged into the correct MTU A and B ports)
1 MTU
1 ECC
1 TED Footprints
0 Spyders
No problem with installation.
All ECC lights are as they should be.
Skipped to Received Packet ratio is 11.5% (It has been as low as 1.7%.)
I noted that TED-reported kWh seemed lower than anticipated.
I compared TED-reported kWh by hour with those logged by my utility.
Hour to hour comparison ranged from 33% to 58% lower than my utility report.
Hour to hour comparison average was 45% lower than my utility report.
I have noted that when I turn on some 120V devices, TED does not register a change.
I have noted that when I turn on 240V devices, TED reports about half of the device's rated wattage.
I suspect that one of my CT's is defective.
I have a DMM.
How do I test a CT to determine if it is good or defective?
Thanks.
