Classification of the Functions of Relay Protection Devices
Types of Protective Relays: Protective relays are categorized by their mechanism (electromagnetic, static, mechanical) and function (time-based, current, voltage). Static Relays: Use electronic components without moving parts. The rectangular devices are test connection blocks, used for testing and isolation of instrument transformer circuits. When a fault occurs, milliseconds matter.
