7.3 Power Factor: Meter display Power factor along with load type indication. Meter
is capable to display both total as well as phase wise power factor
PF consists of 2 things, one is magnitude and second one is load
type. for example if meter is showing 0.855L that means PF
magnitude is 0.855 and load type is inductive. Below are some
sample screens.
At RS485 port, PF will be shown as below:
if PF IS
0.894L (Inductive load) then at port we get 0.894
if PF IS 0.894C (Capacitive load) then at port we get -0.894
7.4 Ampere : Meter can display average as well as phase wise ampere. Average
ampere is given by
in case of star and delta, I
avg
= IR + IY + IB
3
In case of single phase, I
avg
= IR
