The sequenced recloser can be set in several ways such as: 2 fast–2 delay, 2
fast–1 delay and 3 fast–1 delay. The 2 fast–2 delay is employed in this research; this
method provides clearance to the temporary fault that usually occurs along the
distribution network of Luang prabang I substation. The recloser can be used instead
of the circuit breaker and relay, but a sequenced operation must set to 2 delays.
