Circuit Breaker Analyzer Systems: Precision Diagnostics for Unrivaled Reliability

Overview

In high-voltage substations and industrial power systems, circuit breakers are the guardians of your electrical infrastructure, critical for protecting assets and ensuring continuity of service. Our advanced Circuit Breaker Analyzer Systems provide comprehensive, high-precision diagnostics to ensure the optimal performance, reliability, and safety of these vital components. Designed for maintenance teams, commissioning engineers, and testing laboratories, our systems empower you to detect potential failures proactively, reduce costly downtime, and extend the operational lifespan of your critical assets.

Key Features

Our Circuit Breaker Analyzer Systems integrate a suite of powerful diagnostic tools within a robust, user-friendly platform:

• Precision Timing Analysis:
  • Measures and records opening and closing times for all main and auxiliary contacts.
  • Captures breaker-make (B/M) and pre-insertion resistor (PIR) operation times.
  • Determines phase-to-phase and phase-to-ground synchronization.
  • High-resolution time base for unparalleled accuracy (typically ±0.05% of reading ±0.1ms).
• Static and Dynamic Contact Resistance Measurement (DRM):
  • Applies a high-current injection (up to 600A) to measure the static resistance of main contacts, assessing wear and tear.
  • Performs Dynamic Contact Resistance Measurement (DRM) during opening and closing operations, revealing the condition of arcing contacts and identifying localized hot spots or erosion.
• Coil Current & Voltage Analysis:
  • Monitors and records coil current and voltage waveforms during operation.
  • Diagnoses issues such as inefficient coil operation, auxiliary switch malfunctions, or coil aging.
  • Includes internal or external DC power supply options for independent coil testing.
• Motion & Velocity Measurement:
  • Utilizes linear or rotary transducers to accurately measure breaker contact travel, velocity, overtravel, and rebound.
  • Provides critical insights into the mechanical integrity, damping characteristics, and operational health of the breaker mechanism.
• Auxiliary Contact Timing:
  • Tests the precise timing of auxiliary contacts relative to main contact operation, ensuring proper interlocking and control system functionality.
• Minimum Trip Voltage/Current Testing (Optional):
  • Determines the minimum voltage or current required to trip the breaker, ensuring it will operate reliably under fault conditions.
• Integrated Control & Power Supply:
  • Many models feature built-in DC power supplies for coil operation, eliminating the need for external power sources during testing.
• Intuitive Software & User Interface:
  • User-friendly graphical interface (PC or integrated touchscreen) for easy test setup, execution, and data visualization.
  • Guided test sequences, automatic result analysis, and customizable test plans.
• Robust Data Management & Reporting:
  • Stores extensive test data, waveforms, and results internally and/or on external media.
  • Generates comprehensive, customizable reports in various formats (PDF, Excel) for documentation, compliance, and trending analysis.
  • PC software for advanced data analysis, historical comparison, and condition monitoring.
• Portable & Rugged Design:
  • Engineered for field use, featuring durable enclosures, high ingress protection (IP) ratings, and lightweight designs for easy transport to substations and industrial sites.
  • Operates reliably across a wide range of environmental conditions.
• Safety Features:
  • Integrated safety interlocks, emergency stop buttons, and robust insulation ensure operator safety during high-voltage testing.
