Utilities have been looking to improve performance metrics as a means to meet regulations since the late 1990s. One of the most reliable ways to improve power availability and reliability indices and to comply with regulatory standards for uptime is to quickly determine fault locations, isolate faults, and automatically restore power to healthy feeders. G&W Electric has been installing Fault Location, Isolation and Service Restoration (FLISR) solutions for over 20 years.
Features and Benefits
Reduce duration of power outages from hours to seconds
Improve power availability and reliability indices
Attract and retain commercial and industrial customers
Enhanced operational efficiencies
System integration of new and existing components from various vendors utlizes previous investments
Up to 5 years parts and performance warranty on entire system guarantees full support during the critical first years after commissioning.
The same configuration details as stated in Automatic Source Transfer with the addition of the following:
Closed Loop: The fastest option with restoration times as fast as 8 cycles. Closed loop solutions are a great choice for universities, military bases, or other locations that require uninterruptible power.
Open Loop: Allows for fault isolation and restoration within seconds. Open loop solutions are typically best for most commercial and residential circuits, and municipal customers.
Multi-Source Network: Indicates greater than two sources feeding a circuit. These applications frequently involve more advanced algorithms like load flow and source prioritization. Multi-source networks solutions are excellent for local utility circuits, some campus environments, downtown circuits, and rural circuits.
Architecture: Automation logic can either reside in each switch control/relay (decentralized) or in a centralized control.
Communication: For decentralized schemes, communication between devices (peer-to-peer) is optional. Communication is mandatory for centralized schemes. Communication options include fiber optic, cellular, radio, or mesh network.
Single Phase FLISR: Is an additional option to further improve reliability indices by only isolating the single phase that is affected by a fault.
Talk to your G&W Electric sales representative about a LaZer Automation pilot project. Start small with a proof of concept and gain support internally. You can grow from there as all LaZer solutions are scalable.
Schedule a free consulting meeting with a LaZer Automation team member to take a look at a single-line diagram for circuits with poor performance or circuits with critical loads and discuss what LaZer Automation can do for you.
