7-4 AC/DC Reactor
AC Input Reactor
Installing an AC reactor in the input side of an AC motor drive can increase
power factor, reduce input current, increase system capacity and reduce interference generated from
motor drive. It also reduces momentary voltage surges or abnormal current spikes. For example, when the
main power capacity is higher than 500 kVA, or when using a switching capacitor bank, momentary voltage
and current spike may damage the AC motor drive's internal circuit. An
AC motor drive protects it by suppressing surges.
Installation
Install an AC input reactor in series with the main power to the three input phases R/ S/ T as shown
below:
