Auto Sectionalising Links (ASLs) are extensively used on Scottish Power Energy Networks' overhead line networks in conjunction with pole mounted auto-reclosing circuit breaker to minimise the numbers of Customer Interruptions following a network fault.

Scottish Power Energy Networks has experienced some problems with mal-operations of an earlier vintage of units. The ASL testers that can be distributed to maintenance and fault operations overhead line staff that will allow them to test ASLs in the field allowing healthy units to be reused immediately on the network.

The development of a portable ASL (smart link) tester for use in the field to confirm performance prior to installation.
