#99659 - power metering Responding to: ???'s previous message |
As there will be changing phase shift between the current and voltage depending on load, for proper power metering it is necessary to measure rms of (voltage*current).
An interesting concept: http://www.appliedp.sk/en/a-tttc.htm . Jan Waclawek |
