Main components of ekor.gid 

General Instructions

ekor.gid 

The components available in the ekor.gid unit Low Voltage 

compartment are the following:
1.  PLC concentrator
2.  Low Voltage network monitor(s)
3.  Power supply equipment
4.  Ethernet gateway
5.  Connection and protection components: terminals and 

miniature circuit-breakers

3.4.2.  Cubicle-mounted

The cabinet area corresponding to Low Voltage is 

designed as a highly safe area since it has a second plastic 

(polycarbonate) enclosure which electrically isolates all 

the elements housed inside from the metal enclosure in 

contact with the cubicle. The main characteristics of the 

polycarbonate are:
1.  Self-extinguishing material. 
2.  Shock resistant. Withstands impact tests with a 4.11 kg 

steel ball (DIN 52290).

3.  High degree of light transmission. Up to 88-90% for a  

3 mm thick sheet.

4.  Very lightweight, with a density of 1.2-3.6 kg/m2. Half 

of that of glass.

5.  Temperature performance limit: 80 ºC without 

deformation.

This polycarbonate enclosure guarantees isolation between 

the components housed inside and the rest of the cabinet. 

All the cables and elements are isolated from the metal 

enclosure, which will be at the potential of the cubicle 

where it is installed.

In order to increase operating safety, a Low Voltage voltage 

indicator is installed, which lights up whenever there is 

voltage in the ekor.gid-s power terminals.

The Low Voltage Compartment is the place where all the 

components that allow carrying out the Telemanagement 

of the Transformer and/or Switching Substation are housed. 

These components are referenced to the Low Voltage 

neutral potential. Since the enclosure of the ekor.gid-s 

unit is at protective earth potential, all the components 

are integrated on polycarbonate to prevent insulation 

problems. 

The components available in the ekor.gid-s unit Low 

Voltage compartment are the following:
1.  PLC concentrator
2.  Low Voltage network Monitor(s)
3.  Digital inputs module
4.  Power supply equipment
5.  Ethernet gateway
6.  Connection and protection components: terminals and 

miniature circuit-breakers

3.4.3.  PLC concentrator

The primary function of the Concentrator that is integrated 

inside the Smart Distribution Management Unit is the 

communication of the latter via Power Line Communications 

or Low Voltage PLC communications, with the digital meters 

used for the electricity supply for domestic customers. At 

the same time, this Concentrator is connected to all the 

ekor.gid Communications components, with the purpose 

of transmitting the readings to the Customer Management 

Centre. 

The PLC Concentrator, as with the Low Voltage meters, is 

programmed with the PRIME communications protocol 

and this protocol is used for communications between the 

Concentrator and the Low Voltage meters.

Additionally, the PLC Concentrator includes a platform or 

Server for Web applications. 

The PLC signal entering the Concentrator from the 

Substation's Low Voltage board is protected or insulated 

against short-circuits. 

The Ethernet output of the PLC Concentrator that is 

connected to the Communication components available at 

the upper part of the ekor.gid unit is connected to a 10 kV 

Ethernet insulator. 

This component provides the insulation of the 

communications components (which are at protective 

earth potential) with respect to the equipment housed in 

the ekor.gid unit's Low Voltage area up to a 10 kV voltage 

level.
