Grid and system protection relays | Choosing the Right Protection Relay
Protection relays can be divided into two main categories: digital relays and electromechanical relays. Digital protection relays Digital protection relays, also known simply as "digital relays", are made up of an electronic system with microprocessors. These microprocessors make it possible to analyze various grid parameters, such as voltage, intensity, or current to detect faults in an industrial control system. Thanks to microprocessors, these relays can...
