      Easy Device Configuration—A user-configurable device hierarchy allows you to quickly identify your power system devices, such as relays, meters, and distribution controllers. The spreadsheet-style editor makes finding and editing one or many settings simple. Powerful compare and merge features allow you to manage settings across multiple devices within a single screen.

      Powerful Protection Visualization—The Device Overview feature provides an immediate high-level summary of how you are using your devices’ capabilities. It offers rich, graphical views of device protection functions.

      Comprehensive Reporting—With Grid Configurator, viewing and downloading reports for an entire substation at once is simple. Filter by date, report type, or device type and download the reports to your laptop with a click.

      Quick Settings Deployment—Grid Configurator allows you to connect to multiple networked devices at once, deploying settings and downloading reports without moving cables from device to device. It provides a report at the end of the process to let you know if there were any concerns during download.

      Simple Migration—Avoid data re-entry, decrease settings errors during setup, and save time by importing settings results from external calculation tools into Grid Configurator. Duplicate saved device settings when configuring multiple replays or entire substations with similar designs.


        1. 1

          Work efficiently and accurately using the spreadsheet-style editor to configure a single device or a large group of devices.

        1. 1

          See device configuration highlights and core protection functions in a graphical format.

        1. 1

          Create and edit multiple lines of SELogic control equations at once with the help of functions like autocomplete and element lookup. Easily search for elements relevant to the logic equation.

        1. 1

          Identify, filter, and download relevant IED reports from multiple devices to your laptop with a simple click.

        1. 1

          Deploy settings to multiple devices at once without having to move cables from device to device.



      Simplifying Setting Management

      The user interface allows you to create settings for one or many protection functions in a single view. With Grid Configurator’s spreadsheet-style editor, custom filters, and bulk copy-paste feature, you can easily find, edit, and manage settings in a single device or across large groups. Intelligent copy-paste allows you to calculate settings in third-party spreadsheet software and copy-paste them directly into Grid Configurator. The software will match device and setting names with its internal database and update values accordingly. Combined, these features deliver a seamless and efficient configuration experience.

      Making SELogic Editing Intuitive
      With the free-form logic editor in Grid Configurator, you can edit multiple lines of SELogic control equations at once or target your edits to a single line. The editor autocompletes your logic by offering relevant suggestions. It includes tooltip functionality that provides element definitions and search capabilities (e.g., element lookup) that help you locate elements relevant to the logic equations.

      Integrating Your Software Systems
      Grid Configurator integrates with the Device Manager in acSELerator QuickSet SEL-5030 Software so that you can work with a growing fleet of SEL devices. The system provides complete settings validation in order to reduce the incidence of settings errors, helping you simplify complex engineering processes.

      Setting Up a Time-Domain Link (TiDL) Technology System
      Configuring a TiDL system is quick and easy using Grid Configurator. In the TiDL I/O Map view, you can indicate the physical and logical connections between your TiDL relays and SEL-TMU TiDL Merging Units and then commission your devices. The software can also generate a commission report that details the specifics of your TiDL system for record-keeping and review.

      Connect with Third-Party Software and Custom Scripts
      Use SEL-5231 SEL Configuration API to access and manage device configuration data from other software, without requiring detailed database schema or extensive custom code to parse settings files. Grid Configurator can export device settings to common formats like HTML, JSON, and CSV for reporting, documentation, and integration with other software.
