Power transformers and distribution transformers play 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, dis

Relays are electromechanical devices that utilize an electromagnet to switch an electrical circuit. The basic design of a relay comprises a coil, armature, contacts, and a spring mechanism. When current flows through the coil, it creates a magnetic field which attracts the armature, causing the contacts to engage. This action allows for the control
