dv/dt filter compact plus Voltage Peak Limiter

6.2.4.1

Description

The dV/dt filter compact plus Voltage Peak Limiter has two components: The dV/dt reactor
and the voltage limiting network (Voltage Peak Limiter). The voltage limiting network cuts-off
the voltage peaks and feeds the energy back into the DC link.
The dV/dt filter compact plus Voltage Peak Limiter is designed for use with motors for which
the voltage strength of the insulation system is unknown or insufficient.
The dV/dt filters compact plus Voltage Peak Limiter limit the voltage load on the motor
cables to values which correspond to limit value curve A according to IEC/TS 60034-
25:2007.
The rate of voltage rise is limited to < 1,600 V/µs, the peak voltages are limited to < 1400 V.
