Smarter fault management and reliable power restoration.
With ageing LV cable networks seeing a rise in intermittent faults, the problem of multiple fuse operations has resulted in unreliable supply and increased costs. Pair your VisNet Hub with an ALVIN® Reclose² to solve this problem, managing intermittent faults and restoring power on Low Voltage networks.
Up to 80% of intermittent faults can be resolved on the first attempt without the need for substation visits, thanks to the patented design and advanced thyristor technology.
But that’s not all. ALVIN® Reclose² also offers a unique feature called SafeON®. After a power loss, SafeON® conducts checks to determine if the fault is temporary or permanent. If it’s not permanent, ALVIN® Reclose² automatically restores power without the need for a substation visit. In the case of permanent faults, it ensures safety and locks out the system.
Unlock the next level of LV reliability using VisNet Apps and ALVIN Relcose2
Did you know that using insights from our Proactive Reliability App to target the location of ALVIN Reclose2 devices reduces customer outages and duration by 50% compared to fitting after the first non-damage fault? Saving a further 3% CMLs in a typical year if applied to the worst 10% of LV circuits.
Use our handy tool below to gauge how great the savings could be for your company, when you fit a set of ALVIN Reclose2 to your problem circuits.
