Example 14:
Measurement of active power via optional meas-
uring module SPTM 8A1.
Active power is to be measured in the range
-50MW...+135 MW and the corresponding
mA range is -20mA...20 mA.
>99WS90:1:XX
; Measuring module SPTM 8A1 is used
>99WS91:1:XX

>99WS12:-20:XX
; Set low limit of mA signal
>99WS13:+20:XX
; Set high limit of mA signal
>99WS16:-50.00:XX
; Set value of power corresponding to set
low mA signal limit
>99WS17:+135.00:XX
; Set value of power corresponding to high
mA signal limit

; Store set parameters
Example 15:
Measurement of reactive power via optional
measuring module SPTM 8A1. Reactive power
is to be measured in the range 0... 2.2 Mvar and
the corresponding mA signal range is 4...20 mA.
>99WS90:1:XX
; Measuring module SPTM 8A1 is used
>99WS91:1:XX
; Enable power measurement
>99WS14:+4:XX
; Set low limit of mA signal
>99WS15:+20:XX
; Set high limit of mA signal
>99WS18:+0.00:XX
; Set value of power corresponding to low
mA signal limit
>99WS19:+2.20:XX
; Set value of power corresponding to high
mA signal limit
>99WV151:1:XX
; Store set parameters
B) Power measurement using internal current
and voltage signals, measuring modules
SPTM 6A2 or SPTM 6A3.
In this case the measured power is automatically
scaled when the measured current and voltage
values are scaled. The correct measuring module
must be selected and power measurement must
be enabled.
Example 16:
Measurement of active and reactive power via
optional measuring module SPTM 6A2 or
SPTM 6A3. The current and voltage signals
have been scaled already.
>99WS90:2:XX
; Measuring module SPTM 6A2 or
SPTM 6A3 is used
>99WS91:1:XX
; Enable power measurement
>99WV151:XX
; Store the set parameters
The scaled active and reactive power values can
be transmitted to remote control systems over
the SPA, variable V3 for active power and vari-
able V4 for reactive power.
