Relays and contactors are electrical switching devices. This article helps you understand the difference between relays and contactors
Layout, Construction, working, Classification, types, pros and cons, disposal of nuclear wastes and safety in nuclear plants are explained clearly in this article.
Circuit breakers and fuses, in spite of performing a common task of protection, are entirely different from each other. The difference between them are clearly explained in this hub.
High rupturing capacity (HRC) fuses are totally enclosed fuses with a definite-known high-breaking capacity which have been developed after intensive research by manufacturers and supply engineers.
Rewirable fuse is also known as kitkat fuse, is a simple reusable fuse used in homes, offices and in the protection of outdoor distribution transformers. It is available in a wide range of ratings.
An electrical fuse is a simple, less resistive, self-sacrificial, and the cheapest device used to interrupt a circuit under a short circuit, excessive overload, or over current conditions.
IC 79xx (7905, 7912, 7915, 7918) is a three-pin negative voltage controller IC. It is a small integrated circuit used in a circuit to supply a constant negative input voltage.
Transformers are mainly classified into power transformers and instrument transformers. Transformers are also classified into auto-transformers, audio frequency , grounding and welding transformer.
