SMC STT Relay Testing Software

Overview

SMC Smart Test Tools (STT) is advanced software for the Mentor 12 relay test instrument that extends capabilities with batch testing functionality and field-based test execution. STT enables users to store, modify, and execute complex relay test routines stored on USB memory directly on the Mentor 12 without external computing infrastructure, while maintaining full integration with the ROOTS database management system. Test results are automatically recorded and synchronized back to ROOTS for immediate reporting and future reference.

Key Features

• Batch test execution from ROOTS-originated test routines stored on USB memory
• RIO file import for automatic relay operation characteristic definition
• Touch-based test point selection directly on displayed characteristic graphics
• No external computer required for field testing and data collection
• Automatic result recording and appending to each test point
• Customizable test settings and test point configuration before execution
• USB data export for complete test record retrieval into ROOTS database
• Field-based testing eliminates connection overhead and preparation time

Applications

• Field relay testing and commissioning
• Batch relay verification and quality assurance
• Protection system validation in electrical substations
• Relay characteristic testing without external test computers
