3Ø Programmable Resettable Sectionalizer (3Ø PRS), Porcelain Cutout
Brand: Hubbell Power Systems
The Three-Phase Programmable Sectionalizer (3Ø PRS) is specifically designed for the protection of three-phase lateral lines. It has built-in intelligence to distinguish between temporary (transient) and permanent faults on three-phase distribution systems; virtually eliminating nuisance outages. Using radio links to communicate between modules it can automatically sectionalize faults on all three phases. The modules are fully programmable to ensure optimal coordination with system assets.
Three-Phase Programmable Resettable Sectionalizers with porcelain cutout mounting assembly rated for sectionalizing 15kV, 27kV and 38kV three phase overhead distribution lines.
- Coordinates three-phase operation with upstream recloser or breaker
- Synchronized dropping of all three phases protects three-phase loads and avoids downstream system imbalance
- Programmable parameters: Counts, actuating current, reset time
- Historical data storage for system overview and analysis Simplified programming calculates settings based on the upstream reclosing device
- Equipped with In-Air Resettable Trunnion
- Load break and Non-Load break options
