ABB REF615C-D HCFCACABANB2BAN1XD control module
Technical data of product parameters
These requirements are EI813F 3BDH000022R1generally fulfilled without difficulty for
An logic, which can be freely programmed with the aid of FUPLA
(function block programming language), provides convenient facility for achieving special circuits needed for specific applications.The auto-reclosure function enables up to four REF615C-D HCFCACABANB2BAN1XD three-phase reclosure cycles to be carried out, each with independently set
dead time for fast or slow auto-reclosure.
Where necessary, a large variety of supplementary protection
and logic functions is contained in the RE. 216 and RE. 316*4
function software libraries.
The distance protection logic gives the user access for blocking
or enabling purposes to a wide range of functions, including for
example the kind of transfer tripping scheme, switch-onto-fault
logic, zone extension logic, v.t. supervision logic and whether the
protection should trip just the phase concerned or all three REF615C-D HCFCACABANB2BAN1XD
phases for an E/F.
The memory of the event recorder function has sufficient capacity for up to 256 binary signals and their relative time tagsThe memory of the disturbance recorder registers 12 analogue
and 16 binary signals. The number of events it can actually record depends on the total duration of an event as determined bythe amount of pre-event data (event history) and the duration of
the event itself.
Where necessary, a large variety of supplementary protection
and logic functions is available in the MODURES 216 function
software library, which can provide other protection functions
such as restricted earth fault protection or standstill protection.This is the case for phase faults on air-cored compensator reactors and earth faults on power transformers, which are grounded
via an impedance. In some instances solidly grounded transformer can also be protected. REF615C-D HCFCACABANB2BAN1XDEither an overcurrent function with a series resistor or an overvoltage function can be used in a high-impedance scheme. Thapplication of an overcurrent function in a high-impedance
scheme is illustrated by a restricted earth fault protection (R.E.F)
in the following Section.
The required level of through-fault stability is determined by the
value of the high impedance presented by the protection measuring circuit.
