Information

Transformer test bench

You may choose different connections as well as vary the load (even not symmetrical).

Please pay attention to proper grounding of the primary and secondary part of the whole circuit.
The primary and secondary starpoint are available as connectors, if the connection is not delta (D or d).

In some cases it may be necessary to ground the transformer's starpoint even though the source's or load's starpoint are grounded:

• Yy ... Grounding of transformer's primary or secondary starpoint with reasonable high earthing resistance is necessary.
• Yd ... No grounding necessary.
• Yz ... Grounding of transformer's primary starpoint with reasonable high earthing resistance is necessary.
• Dy ... No grounding necessary.
• Dd ... No grounding necessary.
• Dz ... No grounding necessary.
