The arc sensor VA 1 DA is activated by strong light which it
transforms to a current signal. The signal is tranferred via the
slave to the master unit.
The portable sensor VA 1 DP is an arc sensor that can be
temporarily connected to a slave. Attached to persons it
improves the personal safety during work in live switchgears.
The master unit provides up to four trip output channels for
tripping circuit-breakers. By connecting the trip multiplying
relay VAR 4 CE to the outputs, up to 16 trip outputs can be
obtained.
The standard sensor cable length is 6m. Arc sensors can be con-
nected over longer distances, up to 20 m, using a sensor with a
shielded cable.
Thanks to the modularity, the system can be flexibly adapted to
a variety of arc protection applications, ranging from simple
systems with one master unit and one slave unit to complex
solutions comprising multiple master units, for instance, in
applications with selective arc protection.
VAMP220 suits both low voltage and medium voltage
switchgears. It can be installed in new as well as existing
switchgears.
