Automated Reading Commercial Electric Meter , Three Phase
Electricity Meter
The CA368-DC is a three phase four wire BS footprint housing
electric advanced commercial and industrial meter, which integrates
core functionalities, such as powerful e-metering, multienergy data
collection, remote and local communication and end user
interaction. This innovative metering device has been developed as
a core system component of the Calin’s smart metering solution to
optimize daily utility processes.
The meter is capable of communicating with a back-end central
station server through GSM / GPRS / Ethernet connectivity features
provided for Automatic Reading on real time basis. It can be used
in a broad range of commercial and inustrial environments. The
meter is compliant with IEC standard for active and reactive energy
measurement and its terminal block is provided for both direct
connection and CT/VT transformer connection. There is a buld-in
clock in the meter that countsas incrementing second index. This
index is synchronized with the real time in the back-end central
station server at programmed interval. This time synchronization is
giving the utility utmost flexibility of tariff calculation and
system management. This flexibiity futhermore enables the utility
to apply different contractual control to each of the customer with
no need to visit customer's premises to replace their meters from
time to time.
The connectivity of GSM GPRS enables the utility and service
providers to have a real-time monitoring and control on the load in
the grid and improve their managing efficiency at peak hours. The
CA368-DC records maximum demand and load profiling data at
programmed intervals and provides valuable information P, V, A, PF
for the utility and customer as well for them to budget their usage
and manage the load.
Main Features
1) Time of Use (TOU) multi-rate and holiday settings
2) Compatibility and interoperability thanks to open standard of
DLMS /COSEM
3) 4 channels maximum demand measurement and load profile recording
4) Metrological element measurement : voltage, current, power
quality and harmonics.
5) Tamper protection
6) Terminal block for both direct and transformer connection
Key Benefits
