Power transformers and distribution transformers serve crucial roles in the electrical grid, yet they differ significantly in their functions and characteristics. Power transformers are designed to handle high voltages at a large scale, often transmitting electricity over long distances between generating stations and substations. In contrast, di
Principles of Relay Construction and Application
Relays are electromechanical devices that utilize an electromagnet to switch an electrical path. The basic structure of a relay comprises a coil, armature, contacts, and a spring mechanism. When current flows through the coil, it creates a magnetic field which pulls relays-type-construction-application-principle the armature, causing the contacts t
