— THE OUTCOME-BASED REVOLUTION

TerraAlarm provides an enterprise-grade alarm management system built strictly to ANSI/ISA 18.2 and EEMUA 191 standards. Engineered with an enterprise event streaming core, it manages the complete alarm lifecycle, suppresses chattering alarms, and correlates Sequence of Events (SOE) across distributed substations and industrial plants.

What TerraAlarm Will Do

Specific operational functions and engineering capabilities directly sourced from technical documentation.

⚡

Alarm Lifecycle Management

Configurable alarm generation, prioritization, acknowledgment, shelving, suppression, escalation, and closure.

⚡

Event Correlation & SOE Synchronization

Centralized event correlation with synchronized timestamps for Sequence of Events (SOE) disturbance investigation.

⚡

Chattering Alarm Detection & Suppression

Detects rapid oscillatory alarms and automatically applies deadbands or temporary shelving.

⚡

Enterprise High-Throughput Event Core

Enterprise architecture with dedicated tenant data segregation, secure multi-tenant access, and deterministic real-time event streaming.

Real-World Case Study Outcomes

Operational Use Cases & Field Impact

Actual documented use cases across Quality Assurance (QA), Reduced Manpower, Efficiency, and Asset Productivity.

Productivity & Safety

Productivity & Safety (Alarm Lifecycle Management)

Configurable alarm generation, prioritization, acknowledgment, shelving, suppression, escalation, and closure conforming to ISA 18.2 standards.

QA & Forensics

QA & Forensics (Event Correlation & SOE)

Centralized event correlation with synchronized microsecond timestamps for Sequence of Events (SOE) analysis and fast disturbance investigation.

Efficiency

Efficiency (Alarm Analytics & Chattering Suppression)

Automated alarm trending, chattering alarm detection, nuisance alarm pattern analysis, and dynamic alarm flood suppression.

Reduced Manpower

Reduced Manpower (Substation Cascade Trip Protection)

When a transmission line trips, automatically suppresses downstream secondary feeder alarms, guiding operators to the root cause.

Architectural Contrast

Comparison with Traditional SCADA / Legacy Systems

Point-by-point contrast demonstrating the technological shift from legacy industrial automation to the Terrestrial Platform.

Traditional Legacy Systems / Traditional SCADA TerraAlarm Terrestrial Platform Advantage
Hundreds of alarms firing every minute during a trip, overwhelming operators into cognitive paralysis. Dynamic state-based shelving and alarm suppression isolating the single initiating event.
Chattering alarms flickering due to bad sensor wiring or loose thresholds left unaddressed for months. Automated chattering detection algorithms with automated deadband adjustments and health flagging.
Alarms with cryptic 8-character tag names and zero actionable guidance. Context-rich alarm cards with verified Standard Operating Procedures (SOPs) and 1-click mitigation actions.
