Am I Getting Accurate Readings?
« on: September 26, 2012, 07:45:58 AM »
The "present voltage" section on my footprint is hovering around 205.  Does this confirm that I am on a three phase system and not getting accurate readings?  If yes is there a set calculation to determine the variance?

Pic of the footprint is attached for reference.

Thank you for your question vmartin101,

Seeing 205v on present voltage does indeed mean your power is being fed by a three phase system. The TED5000 series cannot accurately measure three phase power. Your best option is to compare your monthly readings to your power bill, pay close attention to the actual meter read date and make an MTU calibration adjustment under Advanced. This will only get you an approximation of your actual usage. I suggest you let the system run for at least an entire month (if you haven't already) before making any changes. You may have to add up to 15% to the calibration factor to get a close reading. Again, this will only give you an approximation of your energy usage.
