About this app

TCC Coordinator is a professional Android app for electrical protection coordination studies.

Build and analyze time-current (TCC) curves, check coordination and damage criteria, draw one-line diagrams, and export multi-page PDF study reports—on device, with optional cloud sync.

Features
• TCC calculation engine covering common protective device types, including IEC and IEEE curve families, fuses, thermal-magnetic and electronic-trip breakers, transformer and cable damage curves, inrush, and coordination checks (CTI, crossing, and damage violations)
• Log-log TCC plot rendered for engineering review, with highlight and study workflows
• One-line diagram builder linked to device instances and curves
• PDF report export (US Letter or A4): project header, one-line thumbnail, TCC plot, device settings, violations, and sign-off sections
• Device library with bundled seed devices, JSON import, and custom devices
• Optional Google or email sign-in for cloud sync across devices; full local-only mode without an account
• Offline-capable local storage with background sync when signed in

Who it’s for
Electrical engineers and protection specialists who prepare coordination studies for industrial, commercial, and utility projects.
