How is this varistor connected in the unit you have ?
Where are the rectifiers is this a vehicle type situation creating a DC output or an AC output machine with rectifiers on the armature to create the rotating permanent magnet ?
How big is the alternator? (vehicle, small building size generator, power station are all quite different .
Also what kind of load and load step size is expected ?
If it is a voltage limiting device you might expect it to be in parallel with the lines that need protection - but what they are, and why they need such protection without knowing more I cannot tell you.
