Relay History. In 1809 Samuel Thomas von Sömmerring designed an electrolytic relay as part of his electrochemical telegraph. American scientist Joseph Henry is often claimed to have invented a relay in 1835 in order to improve his version of the electrical telegraph, developed earlier in 1831. What is an Electrical Relay? (with pictures) wisegeek An electrical relay is a switch that is under the control of another circuit. A classic example is the system used to start a car — when someone turns an ignition key, the ignition does not interact directly with the car battery. Electrical Relay and Solid State Relays for Switching Electrical Relay Contact Types. As well as the standard descriptions of Normally Open, (NO) and Normally Closed, (NC) used to describe how the relays contacts are connected, relay contact arrangements can also be classed by their actions.

How Relays Work | Relay diagrams, relay definitions and ... As relay diagrams show, when a relay contact is normally open (NO), there is an open contact when the relay is not energized. When a relay contact is Normally Closed (NC), there is a closed contact when the relay is not energized. In either case, applying electrical current to the contacts will change their state. Types of Electrical Protection Relays or Protective Relays ... Definition of Protective Relay A relay is automatic device which senses an abnormal condition of electrical circuit and closes its contacts. These contacts in turns close and complete the circuit breaker trip coil circuit hence make the circuit breaker tripped for disconnecting the faulty portion of the electrical circuit from… ANSI device numbers In the design of electrical power systems, the ANSI standard device numbers (ANSI IEEE Standard C37.2 Standard for Electrical Power System Device Function Numbers, Acronyms, and Contact Designations ) identifies the features of a protective device such as a relay or circuit breaker. EEP Electrical Engineering Portal | Energy and Power For All Using earth & phase directional protection where power flow direction might change. Directional protection relay is often used in all network parts in which the direction of flow of power might change, notably in the instance of a short circuit between phases…
