Westrafo Ghana is the official distributor of Westrafo transformers for Africa.

Westrafo rectifier transformers are used in combination with a diode or thyristor (a four-layered semiconductor rectifier in which the flow of current between two electrodes is triggered by a signal at a third electrode) rectifier system. These type of transformers are designed to respect the phase shifting required in a plant that can usually be from 6 to 60 pulses system.

In cases in which the range of secondary voltages is high, the variation is produced through a regulation transformer besides the main transformer, manufactured with several separated units or with a single tank solution (for this type of transformers is required a common agreement between supplier and customer).
