Sizing transformer / current - max. 5 000 A, 72.5 - 765 kV | OSKF
Alstom OSKF current transformer up to 800 kV with a top core design is useful in metering and protection. The transformer featuring a porcelain or composite insulator provides top-quality paper-oil insulation. The transformer with Un: 72.5 to 765 kV, In: up to 5000 A, In short-circuit:up to 80 kA1(Isc dyn: 200 - kA peak), and up to 9 secondary cores has an oil level indicator and allows oil expansion by stainless steel bellows. It is available with high and extended range accuracy design (ERCT) and DC current transformers.
Featuring a design verified by extensive field experience, the current transformer can meet special protection accuracy classes: TPS/TPX/TPY/PR. Compliant with IEC, ANSI/IEEE or equivalent standards, the maintenance-free transformer provides stable accuracy and security against bursting.
