A major Queensland coal-fired power station is set to return to service after it was brought offline by a transformer fault.

Abstract: As one of the key components of a UHV converter transformer, the suitable switching condition of the vacuum on-load tap changer (OLTC) is essential for the stability of the power system. It ...

Abstract: De-energized tap changers (DETCs) offer a cost-effective means of voltage regulation in transformers with steady load conditions, serving as an alternative to on-load tap changers (OLTCs).

Barring something like an incorrect transformer tap connection, an overvoltage is a momentary event in which voltage “surges” beyond nominal. We often call that a transient. A breaker or fuse is ...
