Protection Practice Recommendations And Relay Schemes For Transformer Bus And Breaker Failure Eep from electrical-engineering-portal.com Explanations even stretch as far as the electrical industry, where devices had numbers—a 27 was an undervoltage relay, 43 was a selector switch, and an 86 was a trip and lockout device, so an 86 operation means the affected piece of equipment was out of service. The operator in the bunker could not restore what was locked out without sending someone to the substation. The output contacts of lock out relay are wired to the breaker trip coil circuit. While the outlet's main contactor is open, the efl will continually monitor the resistance of the phase If the 86 is tripped, and until it is reset, the 86 contact in the close circuit is open and prevents voltage from reaching the closing coil. These control relays are often used in conjunction with differential relays for the protection of transformers, buses, and rotating machinery. Relay replaces the following conventional electromechanical overcurrent relays: As the name suggests, this relay once operated locks out the circuit.
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.these types of devices protect electrical systems and components from damage when an unwanted event occurs, such.
Best example for lockout relay is synchronous tnc switch and mater trip relays 86 m, 86 h. The blocking diodes stop the under voltage trip signal from the 27s from reaching the lockout (86) coil & disabling the system. 86 lockout relays are used by many utilities in electrical power transmission substations to trip and hold out of equipment service within a protected zone on the occurrence of protection relay operation which requires inspection and/or repair before the zone may be safely placed back in This relay is also known as master trip relay and its ansi code is 86. Lockout relays 86) usually have a trip coil and a reset handle giving positive lockout and needing a definite manual turning of the reset handle to reset. The relay gets flagged on actuation. Lockout relays are activating multiple contacts at the same time. Lockout relay working function 86: Lock out relay is an electromechanical relay which latches its output contact.
