gabay009 Posted September 3 Share Posted September 3 Hello, I would like to calculate the apparent power using the EM1Data.GetData command. I get the following results: 2024-09-03 23:48:00 total_act_energy : 0.0 total_act_ret_energy : 4.6902 lag_react_energy : 0.5119 lead_react_energy : 0.0 max_act_power : -269.0 min_act_power : -293.3 max_aprt_power : 371.2 min_aprt_power : 344.3 When I do sqrt(total_act_ret_energy² + lag_react_energy²) * 60 I don't get a result between 344 and 371 VAh but I do get 283.20. I therefore think that lag_react_energy does not correspond to VARh. How can I calculate the apparent power from the above results? Thank you very much in advance, Gabriel Quote Link to comment Share on other sites More sharing options...

Power is a instantaneous value. Due to the fact, the output of GetData indicates values in a certain time slot, min and max power values are shown. Calculating power (instantaneous!) from energy values (integrated over time) seems not possible, cause the shape of the curve progression is unknown.
