Advanced Leakage Current Monitor for Surge Arrestors

💡 Proactive Protection for Critical Assets

In high-voltage environments, surge arrestors are the first line of defense against damaging overvoltages, protecting invaluable equipment like transformers, circuit breakers, and generators. However, surge arrestors themselves degrade over time, often exhibiting increased leakage current, particularly the resistive component, long before a catastrophic failure occurs.

Our Advanced Leakage Current Monitor for Surge Arrestors provides unparalleled insight into the health of your surge arrestors, enabling a truly proactive approach to maintenance. By continuously monitoring critical parameters, it empowers utilities and industrial operators to prevent unexpected outages, extend asset lifespan, enhance safety, and significantly reduce operational costs.

✨ Key Features & Capabilities

1. Precision Leakage Current Measurement

• Total Leakage Current (RMS): Accurate measurement of the overall current flowing through the arrestor.
• Resistive Leakage Current (IR): Utilizes advanced algorithms (e.g., 3rd harmonic compensation, voltage reference, or temperature compensation) to accurately extract the resistive component, which is the direct indicator of Metal Oxide Varistor (MOV) degradation.
• Capacitive Leakage Current (IC): Provides insight into the capacitive behavior of the arrestor.
• Harmonic Analysis: Detects and analyzes specific harmonics (e.g., 3rd harmonic resistive current) that are key indicators of MOV deterioration.

2. Continuous & Real-time Monitoring

• 24/7 Surveillance: Constant monitoring ensures no critical event goes unnoticed.
• High Sampling Rate: Captures transient events and subtle changes in leakage current.
• Trend Analysis: Built-in data logging and analysis capabilities for long-term health assessment and predictive maintenance scheduling.

3. Smart Alarming & Notification System

• Configurable Thresholds: Set customized alarm limits for total and resistive leakage current based on manufacturer specifications or historical data.
• Multi-channel Alerts: Receive instant notifications via SMS, email, SCADA, or local visual/audible alarms upon threshold breaches.
• Event Logging: Comprehensive logging of all alarm events with timestamps for fault analysis.

4. Robust & Flexible Communication

• Multiple Protocols: Seamless integration with existing SCADA, DCS, and enterprise asset management systems via Modbus RTU/TCP, IEC 61850, DNP3, or proprietary protocols.
• Remote Access: Secure web-based interface or dedicated software for remote data viewing, configuration, and diagnostics from any location.
• Wired & Wireless Options: Ethernet, Fiber Optic, Wi-Fi, 4G/5G cellular for versatile deployment.

5. Rugged & Weatherproof Design

• Industrial Grade Enclosure: IP65/IP66 rated for superior protection against dust, water, and harsh environmental conditions.
• Wide Operating Temperature: Designed to perform reliably in extreme temperatures (-40°C to +70°C).
• EMC/EMI Compliance: Certified to meet stringent electromagnetic compatibility standards for reliable operation in noisy electrical environments.

6. Ease of Installation & Commissioning

• Non-invasive Options: Clamp-on CTs or direct CT connection for straightforward installation without interrupting power.
• Compact & Lightweight: Minimizes space requirements and facilitates installation on poles or within substations.
• Flexible Power Supply: Operates on AC (110-240V), DC (24-48V), or optional solar power for remote locations.

7. Intuitive Software & Data Visualization

• User-Friendly Interface: Clear dashboards, trend graphs, and data tables for easy interpretation of arrestor health.
• Reporting Tools: Generate detailed reports on arrestor performance, historical trends, and alarm events for compliance and maintenance planning.
• Database Integration: Compatible with standard database systems for archival and advanced analytics.

⚡ Unmatched Benefits for Your Operations

• Prevent Catastrophic Failures: Identify degrading arrestors before they fail, preventing widespread damage to expensive primary equipment.
• Reduce Unplanned Downtime: Shift from reactive to predictive maintenance, minimizing costly and disruptive outages.
• Enhance Safety: Mitigate risks associated with failing high-voltage equipment, protecting personnel and surrounding infrastructure.
• Optimize Maintenance Schedules: Base maintenance decisions on actual asset condition rather than arbitrary time intervals, reducing unnecessary inspections and replacements.
• Extend Asset Lifespan: Timely intervention can prolong the operational life of surge arrestors and protected equipment.
• Improve Grid Reliability: Contribute to a more stable and resilient power grid by preventing equipment failures.
• Cost Savings: Avoid emergency repairs, reduce spare parts inventory, and optimize workforce utilization.
