5.2.3 Power and energy calculation
The relays that are equipped with both a voltage and a current measurement card can calculate power,
and can therefore have power-based protection and monitoring functions (the number of available
functions depends of the relay type). In addition to power calculations, energy magnitudes are also
calculated.
Power is divided into three magnitudes: apparent power (S), active power (P) and reactive power (Q).
Energy measurement calculates magnitudes for active and reactive energy. Energy can flow to the
forward direction (exported) or to the reverse direction (imported).
If a unit has more than one CT measurement module, the user can choose which module's current
measurement is used by the power calculation.
