Cooper Power Systems TCC Editor 3.1

Cooper Power Systems TCC Editor is a specialized utility for creating, viewing, and coordinating time–current characteristic (TCC) curves used in electric power distribution protection. It enables protection engineers and technicians to overlay curves for relays, reclosers, and fuses, adjust device settings, and verify selective coordination before deployment.

Key capabilities:

• Interactive log–log curve plotting with zoom, pan, and precise readouts
• Libraries of standard ANSI/IEC curves plus support for user-defined curves
• Import and export of TCC data and curve files for sharing and archival
• Entry and preview of device settings with immediate curve visualization
• Multi-curve coordination views, annotations, and printable/exportable reports
• Flexible units and scaling (primary/secondary), pickup and time multiplier adjustments

Typical uses:

• Feeder and substation protection coordination studies
• Preparing settings and curve files for field commissioning
• Documenting coordination for reviews and compliance records

The tool is commonly used alongside Cooper/Eaton protection controls and engineering workflows to streamline settings development and produce clear, auditable TCC documentation.
