Description
ABB SAM3.0: Advanced Surge Arrester Monitoring System for Grid Protection
Product Overview
The ABB SAM3.0 is a cutting-edge surge arrester monitoring system engineered to ensure the reliability and longevity of power systems by providing real-time diagnostics of surge arresters. As a core component of ABB’s Grid Protection portfolio, the SAM3.0 delivers precise leakage current measurements, surge event classification, and fault recording, enabling proactive maintenance and minimizing downtime in high-voltage networks.
Designed for medium- and high-voltage applications (up to 765 kV), the SAM3.0 integrates a split-type architecture with a current sensor (optional cable lengths up to 10 meters) and a remote display unit (IP65-rated for outdoor use). This modular design allows installation in hard-to-reach locations, such as switchgear bays or overhead lines, while the digital interface provides instant access to critical data: total leakage current, surge count (up to 2,000 events), and surge classification (Class 1: 0.1–1 kA, Class 2: 1–10 kA, Class 3: 10–100 kA) 1.
The SAM3.0 supports Modbus RTU and IEC 61850 protocols, enabling seamless integration with ABB’s MicroSCADA Pro and ABB Ability™ Condition Monitoring platforms for centralized grid management. Its self-diagnostic capabilities (99% fault coverage) and EMC-robust design ensure stable performance in harsh environments, from -40°C to +70°C 1. By converting raw data into actionable insights, the SAM3.0 empowers utilities and industrial users to optimize maintenance strategies, reduce operational costs, and extend arrester lifespan by up to 30% 1.

Key Features and Advantages
Precision Diagnostics: The SAM3.0 measures total leakage current with ±1% accuracy, detecting early signs of arrester degradation (e.g., internal moisture ingress or resistor aging) 1. Its surge classification algorithm differentiates between lightning strikes and switching transients, providing granular data for grid resilience analysis.
Modular Flexibility: The split-type design allows the display unit to be mounted up to 10 meters away from the sensor, ideal for retrofitting existing substations or overhead lines. The hot-swappable sensor enables replacement without power interruption, reducing maintenance downtime by 50% 1.
Digital Integration: By connecting to ABB’s Ability™ platform, the SAM3.0 supports predictive analytics, such as forecasting arrester failure risks based on historical data. This reduces unplanned outages by up to 40% compared to traditional time-based maintenance 1.
Robust Environmental Performance: With IP65 protection and EMC immunity (IEC 61000-6-2), the SAM3.0 withstands extreme temperatures, humidity, and electromagnetic interference common in offshore wind farms and industrial plants 1.
Compliance and Safety: The system meets IEC 61508 SIL2 standards for safety-critical applications and offers optional ATEX certification for hazardous environments, ensuring compliance with global regulatory requirements 1.
