Applications
2.4. Automation
The Automated Transformer and Switching Substations
include the equipment and technology necessary for
carrying out the Remote Control and Automation of the
network, as well as the remote reading of the meters.
To accomplish this, the Transformer and/or Switching
Substation includes the following components:
Equipment for automation of the network installed in the
Medium Voltage switchgear of the Transformer and/or
Switching Substation.
An ekor.gid unit which includes:
1. Communication components
2. PLC concentrator
3. Low Voltage network Monitor(s).
4. Ethernet gateway
In cases in which the Substation is automated, in addition
to having an ekor.gid unit, the Substation includes at least
one ekor.uct unit or a cgmcosmos-2lpt Compact Cubicle
with Integrated Remote Control Equipment, through which
the automation and remote control of the entire Substation
is carried out.

The Automation of the Medium Voltage network is an
ekor.uct Compact Remote Control Unit or a
cgmcosmos-2lpt
[2]
Compact Cubicle with Integrated
Remote Control Unit, which has the following functionalities
implemented:
1. Operation and status of the Medium Voltage switchgear.
2. Directional fault indication. This functionality facilitates
the location of damages inside the Electrical network.

cgmcosmos-2lpt
Compact Cubicle with Integrated Remote Control
Unit.
3. Metering of the Medium Voltage electrical parameters:
voltage, current, active power and reactive power.
These measurements are meant to optimise the energy
flows.
4. Enable alarms using different sensors:
- Water or level sensor
- Fire or smoke sensor
- Presence of personnel at the Substation sensor or
intruder alarm
- Transformer temperature sensor
- etc.
5. Medium Voltage transformer position trip with
presence of any alarm (fire, water, etc.).
6. Communications protocol IEC 60870-5-104
implemented in the ekor.ccp unit for communicating
with the Operation Control Centre through the
ekor.gid.
7. Web server included with the ekor.ccp Programmable
Cubicle Controller for consulting all the functions
available in the ekor.ccp unit as well as modifying
settings and updating functionality.
8. Possibility of programming restore-service automations.
9. Power supply equipment:
There is a direct current power supply that is connected
to the Substation's Low Voltage Board. This power
supply equipment adapts the direct voltage level to
the power supply both for internal components and
all the equipment available in the ekor.gid unit. It also
charges the batteries included with the ekor.uct unit,
which allows feeding these components in the absence
of voltage.
