Explanation
Function Used to Compute the Average Active Power during Integration
This function computes the average active power within the integration period. It is
derived by dividing the watt hour (integrated active power) by the elapsed time of
integration. The result can be shown on display C. When displaying the average
active power, “
” is displayed at the front of the value.
Average active power during integration (W) =
Elapsed time of integration (h)
Watt hour (Wh)
Computing Method and Displayed Information of Average Active Power while
Integration Is in Progress
: Displays the computed result of (watt hour of element 1 Wh1)/the elapsed
integration time
: Displays the computed result of (watt hour of element 2 Wh2)/the elapsed
integration time (760503 only)
: Displays the computed result of (watt hour of element 3 Wh3)/the elapsed
integration time (760502 and 760503)
: Displays the computed result of (watt hour of element S SWh3)/the elapsed
integration time (760502 and 760503)
* The value of watt hour ΣWh varies depending on the wiring system. The value that results is
derived by replacing “W” in the table on page 5-2 with “Wh.”
Note
This computation function is enabled during integration (while the integration is in progress or
while the integration is suspended). If the integration is reset, the watt hour and the elapsed
time of integration become zero, and the display shows “ -----.” For details on integrator
functions, see chapter 6.
