analysis of voltage transients in a medium voltage system
... Impulsive transients are caused mainly by lightning strikes. The worst impulsive transients are created when the lightning strikes directly on the power line. However the majority of direct strikes lead to a fault, which shows up as a voltage dip at the equipment (monitor or end-user equipment) term ...

Metadyne
A metadyne is a direct current electrical machine with two pairs of brushes. It can be used as an amplifier or rotary transformer. It is similar to a third brush dynamo but has additional regulator or ""variator"" windings. It is also similar to an amplidyne except that the latter has a compensating winding which fully counteracts the effect of the flux produced by the load current. The technical description is ""a cross-field direct current machine designed to utilize armature reaction"". A metadyne can convert a constant-voltage input into a constant-current, variable-voltage output.
