Direct Manufacturer Automatic Reclosing Relay (DRA)
Automatic reclosing relay is designed to initiate multiple reclosures of a circuit breaker which has been tripped by protective relaying. It is essentially a timing device, with a heavy-duty stepping switch
Direct Manufacturer Type RC Automatic Reclosing Relay
Should reclosing be otherwise unsuccessful the motor is stopped at an intermediate lockout posi-tion, with subsequent single shot reclosing only when the line becomes re-energized and is in
Direct Manufacturer Reclosing Relays
This relaying scheme, Figure 9, provides automatic reclosing of a circuit breaker on a previously faulted line at remote station, as soon as the line is successfully energized at another terminal.
Direct Manufacturer What is Auto Reclosing?
Auto reclosing is a phenomenon in which the breaker tries to reconnect the line between two points with the delay or without delay at the time
