Automatic Voltage Stabilisation

automatic voltage stabilisation

Adding some buck/boost transformers to the variacs with automatic voltage control would allow a voltage stabilisation power circuit to be created.

Such arrangements can be provided as three-phase or three single phases. The three single-phase arrangement is a little more costly as three control arrangements are required but it does provide the advantage of correction of each individual phase to neutral voltage.
