6.20 Testing an
automatic recloser
Sverker can be used to measure partial times in a
reclosing cycle. The relay times and the de-ener-
gized intervals are stored so that you after the
measurement can scroll through them on the display
whenever desired. The Sverker make/break contact
can be used to stimulate the state of the breaker for
the automatic recloser.
1. Initial setting: OFF. Main knob at 0. Set
Sverker to measure reclosing (see explana-
tion of settings in Chapter 5). You can also
set a time limit so that the test will be
interrupted when the time limit expires.
2. Connect the reclosing signal to the Sverker
timer start input (START). The relay tripping
signal must be connected to the timer stop
input (STOP). Connect the relay current
input to a suitable current output on
Sverker. If the automatic recloser requires
a breaker-state indication signal, you can
create such a signal by connecting the
