table - power calculation method:
The table outlines the sections' Parameters including Definition:
The amount of Active Power consumed as usable energy. Sometimes referred
to as Real Power. The portion of power flow that, averaged over a complete
cycle of the AC waveform, results in the net transfer of energy in one
direction expressed as kWh.
Elspec calculates the Active Power accurately by taking all Harmonics up to
the 40th into account using the following formula:
i = Harmonic
j = Phase
The amount of Reactive Power consumed as unusable energy. Energy that
flows back and forth with no actual power flow. Reactive Power flow
transfers no net energy to the load and is sometimes referred to as Wattless
power. Elspec calculates reactive power using the following formula:
Elspec calculates the sign of Q using the following formula:
Sign of Q = sign of:
The amount of Apparent Power; a vector addition of the Active and Reactive
Power. The combination of active and reactive energy (kVAh)
Elspec uses formula:
