7.4. Measurements historical report
7.4.1. General description
The protection keeps in non volatile memory a queue of
400 historical measurement records, retrievable from a PC
(protections console).
Each record includes the maximum and minimum average
currents, the maximum and minimum average single
voltages and the maximum and minimum active, reactive
and apparent power (computed within a programmable
time window) detected during an also programmable
register period. The currents are secondary amperes, and
the voltages are secondary volts.
The operation detail is the following: Every second, the
current (three phase average) values, the voltage (three
phase average) values, and the power values are added to
their respective accumulators; when the time screen is over
the accumulated value is divided into the window number
of seconds, in order to obtain he average value. When the
programmed register interval is over, the maximum and
minimum values of the measurements obtained in this
interval are registered.
The register interval is automatically synchronised with he
clock, so if 15 minutes are programmed, 4 registers will be
done every tour, that is at 0, 15, 30 and 45 minutes.
Calendar mask operation:
If the setting "mask disabled” is at "YES" the register is done
everyday of the week. If it is at "NO" what is programmed
for each day has to be taken into account. If one day it is at
“YES” it is registered, if it is “NO” it is not registered.

7.5. Statistical data
The same information can be obtained by keyboard/display
or through PC (screen "statistical data"):
1. kI
2
sum (square kA interrupted by each breaker pole)
2. Automatic reclosing counters:
a. First reclosing
b. Second reclosing
c. Third reclosing
d. Fourth reclosing
e. Total
3. Breaker openings counter (by tripping or by manual
opening)
4. kI
2
sum (square kA interrupted by each breaker pole)
5. Equipment start counter (only per display)
All these counters can be set to 0, and the kI
2
sum set to the
initial value programmed as setting.
Besides, through PC we can see counter breaker openings
by trip or manual.
