Description of
operation

The feeder protection relay SPAA 341 C /E351
is a secondary relay system to be connected to
the current transformers of the network section
to be protected. The feeder protection relay
includes three protection relay modules:

three-phase combined overcurrent and earth-
fault relay modules type SPCJ 4D28 and type
SPCJ 4D28/E351 and an auto-reclose relay
module type SPCT 5D54.

Combined over-
current and earth-
fault relay modules
SPCJ 4D28 and
SPCJ 4D28/E351

The overcurrent unit of the combined overcur-
rent and earth-fault relay module SPCJ 4D28
and SPCJ 4D28/E351 is intended to be used for
single-phase, two-phase or three-phase overcur-
rent protection. It includes three overcurrent
stages: I>, I>> and I>>>. An overcurrent stage
starts, as soon as the current on one of the phases
exceeds the setting value of the stage concerned.
Should the stage still be started when the operate
time selected for the stage elapses, it trips the
circuit breaker by delivering the configured trip
signal.

The earth-fault unit of the combined overcur-
rent and earth-fault relay module SPCJ 4D28
and SPCJ 4D28/E351 is intended to be used for
non-directional earth-fault protection. It in-
cludes two stages: a low-set stage I

0

> and a high-

set stage I

0

>>. When starting the stage provides

a start signal which can be programmed to
operate as the desired output signal. Should the

earth-fault persist when the operate time elapses,
the stage delivers a trip signal.

The low-set stages (I> and I

0

>) may have a

definite or an inverse time characteristic, whereas
the high-set stages operate according to the
definite time characteristic only. The operation
of the stages can be totally blocked by means of
the configuration switches.

The overcurrent and earth-fault relay module
SPCJ 4D28 and SPCJ 4D28/E351 also pro-
vides protection against phase discontinuity.
This phase discontinuity protection stage moni-
tors the minimum and maximum phase current
and calculates the differential current

∆

I be-

tween the phases. The stage provides a trip
signal if the differential current is greater than
the setting value when the set operate time
elapses.
