I am using ADE7758 to measure the V, I and Energy. Up to now, I am able measure Real Power (AWATTHR) and Apparent Power (AVAHR) using the line cycle accumulation method using the steps shown in page 49 of the datasheet. However, for the next step of measuring the Reactive Power (AVARHR), I am having some difficulties. According to the datasheet on page 48 Figure 81, inductive load of power factor 0 is needed in order to calculate the AVAR gain. My concern is getting the inductive load of zero power factor to obtain the test system. May I know any easily available equipment that is suitable for this case?
