Power Factor - Hameg HM8015 Handbuch

Power factor

In general the power factor PF is derived:
P
PF = – – – –
S
PF = power factor
S = apparent power
P = active power
In the very special case of sinusoidal
voltage and current the power factor
equals
PF = cosϕ
HINT
If e.g. the current is rectangular while the voltage
is sinusoidal the power factor will be P/S. Also in
such case the reactive power can be determined
as demonstrated in the following example:
û = 325,00 V
î = 12,25 A
