4.3. DEMAND
To access the maximum demand control parameters configuration screen, position the cursor
over
DEMAND and confirm by pressing SET.
Parameters that can be configured on this screen follow:
Period : Integration window minutes used calculating the maximum demand. Values can
be programmed from 1 up to a maximum of 60.
Win. type : It is possible to select between two window types to calculate the maximum
demand. These are:
• FIXED : Each period duration initializes the maximum demand value. If
programmed for 15 minutes, the measured values are integrated every
15 minutes, and the values for the next 15 minutes are set to zero.
• MOVING : The beginning and end of the integration period moves with each sample
collected. The calculation for maximum demand is made with the
values, in the integration time, each time a new sample is recorded.
To store the modified parameters in memory, press SET and confirm with OK (F4). To exit without
saving changes press ESC (F3).
Another example of event are showed in times period t1, t3 and t4. They are Sags. They are
configured usually unther 90% of the nominal voltage.
When the voltage goes down unther 10% it is stored as an interruption. That interruption is
showed in period t2.
Thre quality events has to be longer than 10ms. If the duration is less than 10ms, the event will
not be stored but will affect to the calculus of the average value for that period.
