8.2. “v” type ekor.rpa-110-v and ekor.rpa-120-v units
8.2.1. Functional description
The ekor.rpa-110-v and ekor.rpa-120-v units are designed
for general protection of lines, transformer protection, etc.
They are installed in circuit-breaker protection cubicles,
where all protection functions are performed by the
electronic unit.
The main function of this equipment is to protect, i.e. it has
the capability to quickly, unequivocally and quickly detect
anomalies in the network, and to send the trip order to the
cubicle where it is installed safely and without delay. Safety
of the whole tripping chain starts from the correct reading
of the meterings and finishes with the disconnection of the
section affected by the failure or incident. All this chain is
made up of several different parts which interlink in a serial
manner, meaning failure in any of them can lead to an error
in opening or false tripping. Given their importance, the
solutions delivered with these systems are for all the parts
overall.
The equipment can give the trip order directly (with energy
stored in the system itself) on the low energy bistable
release (Binox) and/or on a tripping coil by activating a
physical output.
