MiAFAS™ is a cutting-edge enterprise fault analysis system, purpose-built for industries and power utilities — from small setups to large-scale operations.
It automatically detects, analyses, locates, and reports faults across the power grid, often in near real-time. This reduces outage times by over 50% for most users within just a few weeks of implementation, improving system reliability and minimizing revenue loss.
MiAFAS™ is ideal for industrial facilities, and transmission and distribution operators at both national and international levels.
What does it do?
The system automates processes that would normally take days or weeks, delivering clear insights into fault behavior while ensuring compliance with utility standards.
It automatically detects and classifies faults, analyses relay operations, and provides accurate event sequences and Reports.
Reports and alerts are generated automatically and Shown through dashboards, SMS, and email.
MiAFAS™ is integration-ready and works seamlessly with existing Intelligent Electronic Devices (IEDs) such as Phasor Measurement Units (PMUs), Digital Fault Recorders (DFRs), Sequence of Event Recorders (SERs), Digital Protective Relays (DPRs), Power Quality Monitors (PQMs), and Remote Terminal Units (RTUs).
It supports major communication protocols including IEC 61850, IEC 60870-5-103, Modbus, DNP, SPA, Courier, SEL Fast Message, and more.
Why it matters?
- Faster Restoration – Significantly reduces downtime, improving SAIDI, SAIFI, CAIDI, and CAIFI scores.
- Reduced Field Visits – Accurate fault location detection minimizes unnecessary site dispatches.
- Simplified Compliance – Automatically generated reports help meet regulatory standards such as CEA, CERC, RERC, and local corporate requirements.
- Scalable and Secure – Designed to support local grids or nationwide networks, with strong cyber security measures built in.
- Proven Technology – Powered by advanced fault analysis algorithms that have been used globally for over 30 years by leading utilities and International consultants — tested, trusted, and field-proven.
- Resilient Architecture – Designed with redundancy and fail-safe mechanisms, to ensure high availability and minimal downtime.
In a major deployment for Power Grid Corporation of India Limited, the main system operates from Delhi, with a disaster recovery setup in real-time sync, 3,000 km away near Bangalore.
- Trusted Across India — Ready for the World – MiAFAS™ is deployed by Indian industries, DISCOMs, and TRANSCOs across varied terrains, voltage levels, and regulatory environments.
- Google Maps Integration – Maintenance Crew can easily locate fault areas using mobile devices with Google Maps, and submit real-time feedback from the site.
