Protection Suite 5.0 has multiple ways to capture notes and work with documentation within test plans. The tools include an embedded word processor and test steps specifically designed to open/edit document references or custom forms built within the application. These tools allow companies to continue use of instituted documentation, such as PDF test forms and spreadsheets, and save manually-entered test data into PSX files.

Create messages that display when Protection Suite users initiate particular tests. Embed pictures to show connections or other visual details. Require written responses from testers at certain points during a test procedure. Import/export spreadsheets into tests that recognize embedded formulas as testers enter values in particular fields.

Protection Suite 5.0 test plans also provide the ability to run external programs and exchange data. Use this capability to:

  • read/write settings and event data sourced from microprocessor device communications programs
  • import/export data and files with text editor programs
  • exchange data with user-created custom scripts and batch file programs


Test IEDs with Protection Suite 5.0 and your F6150sv power system simulator. Protection Suite and the F6150sv support virtual I/O (GN/GP) options to match IEC 61850 test configurations. Up to 1024 GN and 1024 GP are allowed.

Use Doble 61850 TesT software to discover an IED (data model and configuration) and build a GCX file that contains the virtual inputs and outputs to test in the system logic. Use Protection Suite 5.0 to import the GCX file and reconfigure the F6150sv for network traffic scanning of GSE messages during IED tests. Protection Suite is used to configure the 6150sv test set to apply sampled values (SV) and GSE simulations to functionally test, receive status messages and collect data from IEC 61850-compliant devices.

  • Import GCX files from Doble 61850 TesT software into Protection Suite
    • Doble 61850 TesT reads SCL files and scans the network for defined GSE messages (GSSE/GOOSE/R-GOOSE) to monitor during Protection Suite IED test sequences
    • Doble 61850 TesT builds GCX/GCX2 files containing digital I/O configurations enabling F6150sv publish/subscribe exchanges of GSE messages
  • Send GCX file to F6150sv using Protection Suite 5.0

PowerBase Lite is a network server database for Protection Suite PSX files. PowerBase Lite replaces Protection Web as an enhanced solution for the management of device nameplate, test plans, results and Doble F-series instrument firmware.

PowerBase Lite provides a secure repository that tracks assignments of PSX files among individual users as they log into the database from Protection Suite. Authentications and upload/download recording simplify administrative supervision over team activities.

  • Protection Suite users are provided with the test files and instrument firmware they need with assurance that PowerBase Lite provides secure backup of their records.
  • Administrators have consolidation with data cleansing and reporting capabilities plus equipment management assistance.
  • The PowerBase Lite database provides the source-of-truth for regulatory and internal compliance evidence.

PowerBase Lite is recommended for small-to-medium-sized teams with limited administrative resources. PowerBase Lite is a Protection Suite license upgrade that works with Advanced, Professional and Office editions and is available with v.4.4.1, v.4.4.2 and v.5.0.

NOTE: Implementation requires the setup of a network server that will host the PowerBase Lite database. This setup is not a service offered by Doble. Please consult your company’s IT department.

The PowerBase Field Module (aka PB Field) connects Protection Suite software to the PowerBase database management system. PowerBase administrators attach PSX files into PowerBase relay records that export through PB Field to be used with Protection Suite software.

PB Field makes it possible for data that is managed in PowerBase to appear in Protection Suite PSX files while keeping existing Protection Suite macros in place. This non-disruptive management and productivity solution controls the start-to-finish procedures expected when performing work assignment tasks in addition to hands-on device testing.

PB Field test routines can be setup with numerous test steps any of which can launch Protection Suite tests or any other custom test sequence apart from Protection Suite. All PB Field test data, including Protection Suite results, are imported into PowerBase where a living history of device data is kept and made available to enterprise asset management, work management and engineering systems.

The PB Field module is a PowerBase v.7.1 license upgrade that supports Protection Suite v.4.4.1, v.4.4.2 and v.5.0.
