Transformers are passive components that transfer electrical energy from one electrical circuit to another circuit or multiple circuits. BS 2857 is a British Standard that particularly covers the specifications for nickel-iron transformer and choke laminations.
BS 2857 specifies essential requirements, test procedures and other information relating to non-oriented and oriented nickel-iron laminations intended for cores for transformer and inductor applications. The surface of laminations is normally oxide coated, but an additional surface coating (e.g. paint or lacquer) may be required by the customer.
BS EN BS 2857 on the specification for nickel-iron transformer and choke laminations is useful for:
Nickel-iron alloys primarily consist of nickel and iron. Depending on their intended use these alloys are fortified with small amounts of other metals like chromium, cobalt, molybdenum, and titanium. There are certain standardized specifications contributing to the performance of components made of nickel-iron alloy.
BS 2857 provides definitions that depict a user-friendly idea of nickel-iron transformer and electric chokes. BS 2857 also provides users with physical, mechanical and magnetic characteristics of nickel-iron transformer and electric chokes which ensure their reliability. The guidelines in BS 2857 help you perceive the specification for nickel-iron transformer and choke laminations that enable you to provide a superior quality product to your customers.
