Bender Grid and System protection

The necessity of the installation concerns first and foremost
Line the so-called island operation, in which more energy
fed back into the public electricity grid as
is taken. In doing so, the module ensures that:
that voltage, frequency and phase position of the
the voltage fed back is in order,
otherwise, the energy producer would be affected by the
contactor to be installed automatically disconnected from the grid.

-Island network detection df/dt (ROCOF) vector shift
-Continuous monitoring of the phase voltage and
line-to-line voltage
-Remote shutdown via ripple control signal receiver
-Test function for the determination of disconnection time
-Test button for the trigger circuit
-The last 300 distribution network faults can be recalled
-Separate switching conditions after threshold infringement
-Monitored voltage range: 0-520V
-Monitored frequency range: 40-70Hz
-Backlight graphics LC display
-Interface RS485
-Mains AC: 70-300V (45-460Hz)/DC
