Operation
18 Verification of safe isolation from supply
Safe isolation from supply can be verified either with an HR or LRM voltage indicator or
with a CAPDIS system.
HR/LRM system
Ö Remove cover from capacitive interface.
Ö Insert voltage indicators in the test sockets of the capacitive interface. If the indicator
does not flash or light up in any case, the feeder is not live. The feeder can be
earthed. If the indicator flashes or lights up, the feeder is live.
Ö Refit covers of capacitive interface to protect it from pollution.
Indications
CAPDIS -S1+/-S2+
Ö Verify safe isolation from supply on the display of CAPDIS-S1+/-S2+
(see Page 31, "Voltage detecting systems").
DANGER!
Mortal danger if safe isolation from supply is verified incorrectly!
Ö Verify the perfect function of the voltage indicator and the coupling section in
accordance with national standards
- on live equipment
- with a test unit according to IEC 61243-5/EN 61243-5
- on all poles
Ö Use only voltage indicators or devices to test the function of the coupling section
according to EN 61 243-5 / IEC 61 243-5 / VDE 0682-415. (There have been no
changes as against the old standard VDE 0681 Part 7 regarding the interface
conditions, so that the corresponding indicators can still be usedn.)
Ö Perform repeat test of interface conditions at the capacitive interfaces, as well as on
the indicators according to the customer’s specifications or national standards.
Ö Do not use short-circuiting jumpers as separate plugs. The function of the surge
arrester installed is not guaranteed anymore if short-circuiting jumpers are used
(see Page 31, "Voltage detecting systems").
