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
Construction and Application Principles of Relays
Relays are electromechanical devices that utilize an electromagnet to switch an electrical connection. 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 the armature, causing th
