Concerns & Challenges 


Solutions & Benefits


Transform to a Digital Substation

Manage thousands of protective devices, functions and substation assets

Centralized Asset Management System
eProtect Asset Management Solution includes an extensive and universal storage database that hosts, vast and diverse data, from unlimited devices including protection relays, CTs, VTs, substation transformers, station batteries, and more.


Achieve a single source of truth for engineering and operation

eProtect uses ETAP Digital Twin Unified Model
Digital twinning allows for an accurate representation of the power system, its characteristics, behavior, and responsiveness under various conditions such that improvements can be made. ETAP Digital Twin is a unified engineering and real-time platform used to model, design, visualize, analyze, predict, control, and provide insight into the management and performance of electrical power systems.


Integrate the asset management system with protection and coordination solutions which will assist engineers in evaluating and optimizing relay settings

Integration with ETAP Design and Analysis
Combine eProtect with power system analysis, coordination studies, automatic protection, & coordination evaluation, arc flash assessment, historical events, real-time operating data, and more to optimize the electrical system for any given condition.

  • Allow relay information to be kept in a central location
  • Automatically retrieve relay information to simplify data collection
  • Built-in templates and mapping without any complex communication

Data Integration and Change Management

Different database for each manufacturer

Vendor agnostic asset management system
eProtect supports the direct import and export of settings information from multiple manufacturer platforms. This allows for a large volume of numerical relay settings to be imported into the database as well as generation of settings file to upload into the protection relays avoiding the need to be transcribed manually.


Time spent on data collection used for Protection and Arc Flash studies

Settings file consumption, generation and management
Once the settings are available in the eProtect database, ETAP protection and coordination analysis software is utilized for settings design and verification unlocking productivity gains in the settings development, evaluation, and management process.


Change management and audit trails

Workflows, Access Control and Notifications
Business logic including workflows handling protection settings can be setup in rulebooks to be company specific. The workflow definition and size are flexible and user-defined. Email notifications can be triggered by workflow events. eProtect tracks changes being made to the network database as well as relay settings database including settings, device modification, and locations are stored in an audit trail.

  • Data repository supporting historical, current, and proposed new versions of relay settings
  • Web-based management system with access levels and editable information and functions
  • Storage of documentation including manuals, application guides, instrumentation diagrams, and settings calculations
  • Organization specific workflows and settings processes

Grid Code Compliance

Ensure compliance with standards and grid requirements

Built-in compliance auditing and reporting
eProtect compliance auditing and management system can setup, save, and store study parameters and intuitively rerun the same study in the future that pertains to NERC PRC or other local standards. View colored-coded study results to easily identify areas of noncompliance that require remedy actions.


Assess relay performance under operating conditions and system disturbances

Verification and Validation of Relay Settings
Advanced Fault Analysis System – AFAS is used to determine fault type, improve fault location accuracy, and provide a thorough assessment and validation of relay settings. AFAS decisions and ETAP Predictive Simulation offer insight into relay performance, setting evaluation, and system-wide protective device operation.

  • Integrated with Advanced Fault Analysis System
  • Generate and print compliance reports
  • Identify and mitigate areas of noncompliance
  • Alerts for unauthorized changes

Remote Management of Protection Relays

23:45 Webinars  
This presentation defines and demonstrates the importance of remote data collection of protection relays for the security and reliability of large power system networks. Oman Electricity Transmission Company grid stations contain more than 5000 rapidly expanding protection relays installed. In case of tripping incidences, the protection system would isolate the faulty primary equipment by actuating the switchgear. These isolated equipment restorations can be done faster if protection relays’ fault records and events can be retrieved through remote access at any time. ETAP and OETC jointly worked to provide remote relay access and data retrieval. The protection system model and relay data feed in a relay management system solution, is called ETAP eProtect. This system is connected through IEC 61850 and IEC 60870-5-103 protocol to linked relays, events, and fault records. Fault records are stored in a database for detailed analysis and validation. This presentation discusses the challenges faced, technical requirements, and benefits of the solution.
