SEL Time-Domain Link (TiDL) Technology

Simplest digital secondary system available
Point-to-point configuration; simple, visible indication of which devices are communicating
Plug-and-operate configuration
No network switches required
No GPS clocks required
Cyber-secure; T-Protocol, by design, won’t operate on traditional networks

Significantly decreases the time it takes a relay to trip in response to an arc fault, reducing hazardous incident energy and saving lives
Combines light-sensing technology with fast overcurrent protection, providing high-speed arc-flash detection and preventing overtripping for external faults
Relays work with low- and medium-voltage switchgear and easily coordinate with other devices in industrial- and commercial-scale facilities

Energy calculation method simply traceable to fundamentals of physics and mathematics
Energy packets are based on watt-seconds and are therefore an accurate representation of energy flowing in an electric network under any power quality conditions
We use energy packets to look at new and more precise ways to monitor, control, meter, and even predict electric power system operations

Preserves deterministic time-division multiplexing (TDM) performance over packet transport with under 1 ms latency
Uses your current TDM-based line current differential protection system with Internet Protocol core networks
Allows packet-based and TDM-based systems to work together, greatly reducing communication migration or upgrade costs
Is simple to configure; designed so you configure the QoS settings for all your critical protection circuits in just one step, saving time and ensuring consistency

The only network system where you can design and deploy how and where network traffic is allowed to flow
Similar to having an individual firewall on every port—an exciting concept for cybersecurity
Redirects network traffic to secondary path instantaneously when network breaks
Inherently provides network configurations, helping meet network audit requirements
Unauthorized traffic entering the switch is flagged and routed to an intrusion detection system

Keeps the lights on by managing generation controls, load-shedding schemes, and automatic synchronization schemes
Uses tie flow control scheme to manage the import of power
Scalable, from managing an entire country’s power system to oil refineries to solar and wind farms
Manages energy costs and determines the optimal generation dispatch based on operational constraints, such as fuel cost, weather, the state of charge mode, and energy import/export costs

Our next-generation wide-area situational awareness (WASA) software that complements SCADA and EMSs by aggregating high-resolution time-series data, including synchrophasor data, relay event reports, point-on-wave data, and GIS geospatial data
Equips transmission control centers with tools to transform time-synchronized data into detailed system insights that support decision making
Built for operators: simple to use and customizable to meet your WASA needs

Automatically collects, stores, and manages device-specific information to simplify day-to-day management of your system of devices and to support compliance
Automates and accelerates the collection of oscillography, Sequence of Events (SOE) data, device settings, property information, and other device files and reports
Provides automated password rotation and streamlines device audits through custom summary reports to identify device changes
Can be deployed across substation or regional installations or centralized at a corporate installation

Simplifies commissioning and testing, firmware management, and cybersecurity, and reduces total cost of ownership by centralizing these functions in one device rather than in several single- or multifunction protective relays
Based on a relay platform your utilities are using right now
Offers flexible deployment solutions, including traditional I/O connections, TiDL, or IEC 61850

Simple—System configurations are created in minutes with no complex modeling required
Scalable—Feeders can be designed and deployed individually and remain operational as new feeders are expanded across the grid
Secure—Runs on SEL Blueframe, a secure, Linux-based operating system designed for operational technology (OT) applications
Fast—Uses protection and switching devices at the grid edge for fault location, increasing the speed of service restoration
Interoperable—Vendor-agnostic with all reclosers that support DNP3, including the SEL-651R Advanced Recloser Control and the SEL-651RA Recloser Control
Versatile—Designed to work on overhead and underground circuits

Fast—Detects and issues trip commands in 1–2 ms, 5 to 10 times faster than traditional protection
Accurate—Most accurate fault locator available; pin-points faults to an insulator on a tower
Reliable—Protection that isn’t dependent on sources; great for areas with high inverter-based resource integration

Uses advanced signal processing to detect high-impedance faults, which can be difficult or impossible for traditional protection to detect
Available in many devices already deployed in your distribution systems, resulting in very little cost to aid in the detection and mitigation of wildfires
Alarms operators for a fallen conductor through SCADA or instructs to open a circuit breaker or recloser control to isolate the affected circuit
