2.2.2. Advanced monitoring of the Low Voltage network
The Advanced Monitoring of Low Voltage is a functionality
that can be included in any of the three applications:
Substation with Basic Telemanagement, Monitored
Substation or Remote Controlled Substation.
In addition to the functions previously described in the
Basic Low Voltage Monitoring, the Advanced Monitoring of
the Low Voltage network allows the following functions:
• Current metering per each one of the Low Voltage board
(or fuse) outputs.
• Blown fuse detection in each Low Voltage line.
• Possibility of developing algorithms for identifying the
Low Voltage connectivity.
• Possibility of fuse temperature detection.

Fuse detail in Low Voltage board
The Advanced Monitoring of the Low Voltage network is
implemented using sensors in the Low Voltage fuses of the
board available in the Substation. These sensors are self-
powered by a 10 A current through the fuse.
Additionally, these sensors have a radio transmitter to
report the information collected in the fuse to the ekor.gid
unit.
In order to receive this information from the fuse, the
ekor.gid unit includes a component called the Ethernet
Gateway that functions as a radio receiver, 10 kV insulator
and MODBUS master.
In its Modbus master function, this Ethernet gateway
also collects the data originating from the Low Voltage
network Monitor(s) (Basic Monitoring data) and makes
them available along with the Advanced Monitoring data,
to send them to the Customer Management Centre via
communications.
