The following power measurements are made:
- Real power (W, kW): measurement as normally registered by energy usage meters.
The full spectrum is used.
- Apparent power (VA, kVA): the full spectrum is used.
- Reactive power (var, kvar): the fundamental frequency is used.
- Harmonic power (VA or kVA Harm): non fundamental frequency powers.
- Unbalance power (VA or kVA Unb): unbalance part of real power.
- Fundamental real power (W or kW fund): the fundamental frequency is used.
- Fundamental apparent power (VA, kVA fund): the fundamental frequency is used.
- Cos ϕ or DPF: cos ϕ is phase angle between fundamental voltage and current. DPF is
(W fund)/(VA fund).
Energy measurements include:
- Active energy (Wh, kWh).
- Apparent energy (VAh, kVAh).
- Reactive energy (varh, kvarh).
- Forward energy (Wh, kWh forw): energy consumed.
- Reverse energy (Wh, kWh rev): energy delivered.
Also the the 12/10 or 180/150 cycle rms values of current and voltage are displayed.
Symbols indicate if a load is capacitive (
) or inductive ( ).
The Analyzer displays power and energy usage by phase and in total.
