Main components of ekor.gid 

3.4.7.  Connection and Protection Components

The ekor.gid Smart Distribution Management Unit includes 

miniature circuit-breakers for protecting the different 

electrical components installed inside it. This ensures the 

integrity of the system against overvoltage problems 

and prevents unnecessary maintenance operations to 

replace defective components or components that are not 

operating properly as a consequence of these overvoltages.

The available protection components are one independent 

four-pole miniature circuit-breaker (3 phases and neutral) 

for each one of the Low Voltage boards that are monitored 

via the ekor.gid unit. 

The characteristics of the four-pole miniature circuit-

breakers are the following:

As connection components, the ekor.gid unit includes 

short-circuitable and disconnectable terminals with 6 

currents per each Low Voltage board to be monitored.

3.5.1.  Telemanaged Substation/Low Voltage network Monitor

Wall-mounted

The wiring corresponding to the currents and voltages 

required for carrying out the functions for telereading of 

meters enters the ekor.gid unit through the base of the 

Low Voltage Compartment, which is protected by the 

polycarbonate enclosure. 

This input wiring is divided into Voltage and Current signals. 

There are 4 voltage outputs (3P+N) and 6 current outputs 

(Ia1-Ia2, Ib1-Ib2, Ic1-Ic2) for each Low Voltage board to 

be monitored. The voltage signals are wired to miniature 

circuit-breakers and, in the case of current signals, to test 

blocks or disconnectable and short-circuitable terminal 

blocks.

These cable feeds to the ekor.gid unit are carried out using 

packing glands without requiring external connectors. 

Figure 3.2. 

Low Voltage wiring in 

ekor.gid

The cables corresponding to Low Voltage signals are 

wired to different connectors that carry out the function 

of blocking the opening or interlocking of the cover used 

for accessing the entire Low Voltage Compartment. These 

components must be disconnected in order to access the 

inside. 

The Low Voltage current signals are inserted into the 

protected area using feedthroughs. 

All the components are supported by an insulated DIN rail 

made of plastic. The wiring is routed using plastic ducts. 

Both the wires and the ducts are halogen free. 

Cubicle-mounted

The cable corresponding to the currents and voltages 

necessary to carry out the telereading functions of the 

meters enters the ekor.gid-s unit through the back of the 

cabinet, via the access fitted for this purpose. 

This input wiring is divided into Voltage and Current signals. 

There are 4 voltage outputs (3P+N) and 6 current outputs 

(Ia1-Ia2, Ib1-Ib2, Ic1-Ic2) for each Low Voltage board to be 

monitored. The voltage signals are wired to the double-level 

terminals and, in the case of current signals, to test blocks or 

disconnectable and short-circuitable terminal blocks. There 

is a Low Voltage indicator which warns of the presence of 

Voltage in the access terminals.
