Figure 5. Protection of a harmonic filter circuit in an industrial network
Figure 5 illustrates the protection of a harmonic filter circuit in an
industrial network. Standard configuration B is used with
overload, three-phase connected current unbalance and
undercurrent protection for the harmonic filter and with an
additional thermal protection mainly for the coil. Overcurrent
and earth-fault protection functions are used for protecting the
feeder cable and harmonic filter circuit combination.

Figure 6. Protection of a single star connected capacitor bank
The protection of a single star connected capacitor bank is
shown in Figure 6. Standard configuration B is used with
overload, voltage-based unbalance (Uob) and undercurrent
protection for the capacitor bank. Overcurrent and earth-fault
protection functions are used for protecting the feeder cable
and the capacitor bank combination.
