Three-phase earthing transformers and static balancers
Power up to 500KVA
The earthing transformer is an electrical device used to derive a neutral wire from a three-phase distribution network that lacks one: this need may arise where it is necessary to connect this neutral wire to earth (earthing transformer), or to allow connection of one or more single-phase loads between the three-phase line and this neutral, managing to maintain balanced single-phase voltage regardless of the number of connected loads (static balancer).
