Note. h: Measurement period, k: 1-hour conversion coefficient
(+): Use this value (amount of consumption for Active Power or amount of lag for Reactive Power) only
when the numerical value is positive.
(–): Use this value (amount of regeneration for Active Power or amount of lead for Reactive Power) only
when the numerical value is negative.
