Overview

Hubbell Incorporated has recently introduced an advanced product designed to enhance both grid reliability and worker safety: the LineDefender™ lateral-protection recloser. This innovative device aims to drastically reduce the duration of power outages and significantly improve operational efficiency.

Key Features

The LineDefender™ represents a turning point in the reliability of electrical grids. It encompasses sophisticated fault management capabilities coupled with several safety features designed specifically for line workers. One of its standout features allows line workers to reset the recloser from the ground by manually toggling a yellow operation handle, which enhances safety and prevents unnecessary risks associated with climbing poles in hazardous conditions.

The recloser is capable of automatically detecting and clearing temporary faults. In instances of temporary issues, it swiftly restores power without needing crew deployment. However, when permanent faults occur, the device will de-energize the circuit to prevent damage and provides visible indications through a semaphore and a flashing beacon. This assists workers in swiftly identifying fault locations and facilitates quicker restoration of services.

Groundbreaking Safety Features

Safety is a prime concern for utility companies. The LineDefender incorporates several groundbreaking safety features:

• - Operating Handles: Familiar to line workers, these handles are integrated within a fused cutout, enhancing comfort and usability.
• - Secure Latching: The recloser remains securely latched within the power fuse cutout, preventing accidental dropouts, while also allowing for visible air-breaks which assure safe working conditions.
• - Hot Line Trip Mode: This unique feature provides best-in-class clearing time under lightly loaded or low fault current situations, prioritizing line worker safety.

Streamlined Operations

In addition to its safety features, the LineDefender is also crafted with operational efficiencies in mind:

• - Versatile Compatibility: It can easily integrate with common overhead line construction and requires minimal maintenance.
• - Visible Indicators: Equipped with indicators that can be clearly seen in various weather and lighting conditions, helping to speed up fault identification.
• - Enhanced Flexibility: Built with balanced weight distribution and guided alignment, it provides line workers greater safety when creating or closing visible air-breaks.
• - Enhanced Connectivity: The device includes integrated local Wi-Fi/Bluetooth pairing and a “plug-on” cellular SCADA module for seamless communication.

Integration with GridHUBB™

The LineDefender recloser works in conjunction with the GridHUBB™ software platform, which allows utilities to manage and control Hubbell’s intelligent grid devices through an easy-to-use interface. GridHUBB is compatible with various operating systems, including Windows, iOS, and Android, offering advanced programming and reporting tools that can simplify utility personnel training.

Conclusion

In summary, Hubbell’s LineDefender™ lateral-protection recloser not only sets a high standard for single-phase reclosers but also reflects the company’s commitment to enhancing grid reliability and ensuring the safety of lineworkers. With its high-tech features and operational ease, it stands to revolutionize utility management and power distribution across various sectors.
