5.- BASIC FEATURES
CIR-eQ analyzer is a programmable measurement unit that measures, calculates and
records the main electrical quality events in single and three-phase electrical networks
in its memory. We must highlight the following concepts:
Serial number: The serial number of
CIR-eQ is an important parameter, since all files
generated by the unit must be identified with that number. The 10-digit serial number
is written on the rear features label of CIR-eQ.
Programming: The unit is programmed with the setup software CIR-e.exe. The
application is stored in the SD card supplied with the unit.
Display: The visualization of the quality events is done with Power Vision and Power
Vision +.
Installation: The analyzer can be installed to analyze balanced (3 wire) or unbalanced (4
wire) single and three-phase networks. The unit must be powered with the auxiliary
power supply cables in any of the connection options. The auxiliary power supply
wires of the unit are Brown and Green.
Measurements: The analyzer takes 128 samples per cycle of the variables in true root
mean square (TRMS). With all of the samples taken, the unit calculates the arithmetic
mean during the recording period selected by the user. The analyzer also records the
maximum and minimum values measured during each period. To take these
measurements, the analyzer has four voltage inputs.
Recording: The unit has a 1 Gb external SD memory, FAT16 format, which stores the
parameters measured or calculated by the analyzer. We must highlight the following
features:
• Stores the quality events detected depending on configuration.
• Stores the parameters instantly (measured for a selected period).
• Stores the maximum and minimum values of the recording period selected.
• The SD memory can be expanded to 2 Gb.
With SD memory of 1Gb the period estimated to register (without EVENTS) is:
Register period Registering time
1 minute 7 year and 6 months
10 minutes 75 year and 11 months
120 minutes 455 year and 7 months
