8.2.4.- Harmonics statistics file (H24)
A series of values to be susbsequently used by the PC’s software will be
stored in this file. The software will calculate typical deviation, the statistical
distribution curve and the effective values at 50%, 95% and 99% of each and every
harmonic recorded by the QNA-P/PV .
8.2.5.- Weekly average values file (STP)
TYhis file will save the averaged weekly values for voltage variables (L1, L2
and L3), frequency, flicker (pst and plt) (L1, L2 y L3), harmonic distortion rate (L1, L2,
L3 and three phase), unblanace and the total number of recordings used for
calculations. The 0%, 5%, 95% and 100% values may also be obtained individually
and as a whole taking into account all recordings, i.e. the whole week or just those
recordings with no voltage events.
8.2.6.- Configuration and operation of the SMS alarms
The QNA-P/PV (GPRS / GSM model only) may configure up to 8 different
alarms. A maximum and minimum limit and a time period may also be set for each
alarm. They also may be sent to 8 different telephone numbers.
8.2.7.- Configuration and operation of the GPRS
The QNA-P/PV (GPRS model only) allows information to be sent to an FTP
server via GPRS. This means that every X minutes the equipment automatically
sends recorded information to an IP address defined by the user. The time period
and the IP address are defined by the user. A user name and password supplied by
the FTP server administrator to save the information must also be defined. This mode
of communication avoids the user having to use a modem to download information,
because it is the equipment itself which sends the information to the FTP server. This
means that the user only requires an Internet connection to connect with the FTP
server and to download the information.
