About this app

INTEGRID is a professional field tool for testing, commissioning and condition
assessment of high-voltage substation equipment — built by substation engineers,
for substation engineers.

Enter your test readings on site, and INTEGRID instantly analyses them against
IS / IEC / IEEE / CIGRE-based limits, flags problems with ranked diagnostic
reasons, and generates a clean, professional PDF test report — all without
internet.

⚡ 11 EQUIPMENT TYPES COVERED
• Power Transformer — IR, PI, winding resistance, tan delta, turns ratio, DGA, oil tests, SFRA
• Circuit Breaker (SF6) — timing, contact resistance, IR, gas parameters
• Current Transformer (CT) — ratio, knee point, IR, tan delta
• PT / CVT • Lightning Arrester • Isolator • VCB
• Earth Pit & Earthing Grid • UG Cable • Bus & Feeder • Thermovision

🔬 BUILT-IN EXPERT ANALYSIS
