ekor.gid
Main components of ekor.gid
The main characteristics of the insulator are as follows:
1. 10 kV passive insulator. Shock resistant thanks to
its polystyrene construction. It does not have any
accessible metallic components.
2. Individual insulation tests for each insulation unit.
Suitable for use in an IEC 601-1-1 (class 3 safety) system
environment.
3. Suitable for 10BASE-T Ethernet (IEEE 802.3) and
100BASE-TX phase Ethernet (IEEE 802.3u) connections.
4. Dimensions 102 x 53.5 x 32 mm
5. Maximum continuous voltage difference between
ports 2 kV DC/ 2.5 kV AC (50 Hz)
6. Coupling capacity ≤ 15 pF
7. Leakage current at 10 kV (10 s) ≤ 5 uA
This isolation component is connected to a switch (available
in the Communications Compartment) to the installation's
safety potential. This way, it is possible to make an electrically
safe local connection to it and access all the information by
means of a single connection line.
This functionality requires optical ports to be available
(without direct contact with the device) in order to
individually connect to each one of the Low Voltage units
(Concentrator and Low Voltage network Monitor(s)), which
means that maintenance work is carried out easily and with
a higher degree of safety.
3.4.4. Low Voltage Monitor(s)
The Low Voltage Monitor is the component in charge of
measuring the instant current and voltage per phase and
calculating the instant power factor per phase as well as the
active, reactive and apparent three-phase power and the
active and reactive energies.
These electrical parameter meterings and calculations
are carried out by each Low Voltage board; therefore, the
ekor.gid unit includes two Medium Voltage Monitors for
cases in which the Substation includes two Medium / Low
Voltage transformers.
The monitors of the ekor.gid unit's Low Voltage network
communicate via RS-485 with the Ethernet Gateway, which
is connected to the communication components, and
they send the information from these to the Customer
Management Centre.
3.4.5. Power Supply Equipment (depending on the model)
The power supply unit is a component connected to the
Substation's Low Voltage Board and from this voltage
provides 230 VAC.
The power supply unit carries out the power supply
and battery charging functions. This unit is linked with
the batteries that are housed in the communications
compartment, which are responsible for providing power
to the ekor.gid unit in the absence of Low Voltage.
This component guarantees power to all the units that
are located inside the ekor.gid unit, whether it is the Low
Voltage equipment or the Communications equipment.
Additionally, this system provides power to the equipment
external to the ekor.gid unit when the Transformer and/or
Switching Substation includes a Medium Voltage Monitor.
For cases in which the Substation is Automated / Remote
controlled, power for the different components of the
ekor.gid unit (including the Low Voltage components as
well as the communications components) is provided by
the power supply system and the batteries available inside
the ekor.uct unit or the Substation's cgmcosmos–2lpt
cubicle.
The main features are as follows:
1. Power supply input: the power supply receives a single-
phase voltage of 230 V
ac
(P+N), although it is possible
to feed it with three-phase voltage (3P+N), which
provides a more reliable service in the case that one of
the phases is lost.
Operating voltage range 110 V
ac
(-20%) at 230 V
ac
(+20%)
2. The power unit also includes the battery charger part
up to 50 W. For this purpose, there is a 48 V
DC
output
which ensures the batteries available in the ekor.gid
unit are charged. The charge is in C10.
3. Power supply outputs:
a. 48 V
DC
at protective earth potential: Power supply
for the communication components of the ekor.gid
unit as well as the Monitoring components in the
case of a network Monitoring Substation.
b. 48 V
DC
at the Low Voltage neutral potential: Power
supply of the Low Voltage components, which are
required for carrying out the Telemanagement (PLC
Concentrator, Low Voltage monitor(s), etc.).
