Detection of insulation faults in grounded voltage systems. The residual
current relay is used to maintain electrical plants before faults occur.
Decrease in insulation can be detected and indicated early without inter-
ruption of operation.

If time is set to 0 and a pulsating fault current is flowing (e.g. 1-way rec-
tified) the output relay may flicker because of the short reaction time. By
increasing the time delay this effect can be avoided.

IL /SL 5882
The function of the IL/SL 5882 and IR 5882 can be compared to a fault
current circuit braker unit. It detects and indicates residual currents, but
does not disconnect.
The measurement is done by an external residual current transformer e.
g. ND 5016 which is connected via terminals i and k to the IL/SL 5882.
At the device IR 5882 the residual current transformer is integrated. All
conductors of the voltage system to be monitored are run through the CT
except the ground wire. In a fault free voltage system the sum of all current
is 0 and the CT induces no secondary voltage. If due to an insulation fault
a fault current flows to ground, the current difference in the CT creates a
measuring current, which is detected and measured by the IL/SL 5882 or
IR 5882. Abrokenwire in thesensing circuit would disable themeasurement,
therefore a special circuit detects broken wire and forces the unit to trip.
The unit has 2 x 1 changeover contacts. Contact 11-12-14 for alarm (AL)
and 21-22-24 for prewarning (VW). Prewarning is detected at 70 % of
the selected alarm value. With external bridge X1-X2 the alarm is stored
and has to be reset by pressing the reset button or by disconnecting the
auxiliary supply. Without bridge X1-X2 the unit works with auto-reset and
the fault is not stored. With the button "Test" a fault can be simulated
(Alarm). Each contact is delayed with an adjustable time delay tv(same
delay time for alarm and pre-warning).
To avoid unauthorised adjustment of the potentiometers the unit has a
transparent cover that could be seald with laquer. Two holes above the
push buttons allow activation of test and reset.

High forces when mounting may damage the current transformer fixtures.
The fixing clips are designed to support the current transformer. Forces
that are applied by the cable running through the current transformer can
only be tolerated within limitations.
During installation and afterwards please make sure that the wires are
led through the current transformer without applying pressure and remain
stable in that position.

Mounting - Srew fixing at ND 5014/120
To high forces applied during installation can damage the transformer on
the mounting foots.
The mounting foots are only designed to fix the transformer. Forces that are
applied to the CT by the conductors can only be supported within limitations.
When installing the CT, the conductors should be lead free through the
transformer and should later stay in that position.
