Special Transformers

General Features

For some applications, the transformer – whether hermetically sealed or conservator, with fins or radiators – has a customised tank design to allow the connection of other components present in the transformation cabin.

These instruments could be a MV or LV circuit breaker or switch. For some markets, the MV and LV terminals can be supplied laterally with the possibility of inspection of the transformer from above using a porthole or by removing the cover.

Single-Phase Transformers

A single-phase transformer is frequently used for power distribution and voltage reduction for residential and lighter commercial applications. Single phase transformers are most commonly used in non-urban areas, where it is not economical to have a three-phase transformer

Grounding Transformers

A grounding (also known as earthing) transformers is a three-phase transformer connected to the power system to provide a missing neutral connection for earthing. Grounding transformer provides a relatively low-impedance path to ground, thereby maintaining the system neutral at or near ground potential.

Rectifier Transformers

A rectifier transformer is a specially designed transformer in order to feed 12, 18 or 24 pulse rectifier circuits. Rectifier transformers are used for industrial processes which require a significant direct current (dc) supply.

Amorphous Transformers

An amorphous metal transformer (AMT) is a type of energy efficient transformer found on electric grids. The magnetic core of this transformer is made with a ferromagnetic amorphous metal. The typical material (Metglas) is an alloy of iron with boron, silicon, and phosphorus in the form of thin (e.g. 25 μm) foils.
