Selected to voltage control mode only, with current limiting reactors and is mainly used for voltage control in networks where required. .
The unit consist of 4 steps which are built into a metal Enclosure.

Each step consists of:
3 x Capacitors or combination per step
3 x Reactors (reactors for current limiting only),
Reactors to be used as filters to cater for harmonics or ripple control
3 x Capacitor Switches with/without Zero Voltage Crossing
(Zero Voltage close control can be included as mentioned under point no 1.)

The enclosure includes all busbars, insulators, interposing relays, controller etc
Several of these units have been installed at Network Tasman.
