    Device automatically returns to display mode if no button pressing for 10 minutes in setup mode or maximum/minimum mode. Reactive Calculation Method Rootech supports two methods for accurate calculation of reactive power. Method 1: General Calculation Method 1 is used to obtain reactive power, and apparent power by using calculation of vector apparent power.
  • Page 38 Fig 3.2 P , Q[according to general calculation] Note When phase difference between voltage and current is within 90 degree of lead and lag, power factor is positive. However, when phase difference is more than 90 degree[miswiring, regeneration], power factor and active power are negative. Method 2: Calculation regarding Harmonics Method 2 is used to obtain reactive power from apparent and active power, and the overall apparent power by using calculation of vector apparent power.
