Dynamic Contact Resistance

Advanced Diagnostic Capabilities:

The DCRM System performs real-time resistance measurements of circuit breaker contacts during opening and closing operations. It detects abnormalities in contact travel, timing, and resistance patterns, offering early warning signs of mechanical wear or electrical deterioration that conventional timing tests may miss.

User-Friendly Operation:

Featuring an intuitive interface and advanced analysis software, the DCRM System simplifies complex diagnostics. Automated test sequences and easy-to-interpret graphical outputs allow for fast setup and efficient evaluation, significantly reducing testing time and operator workload.

High Accuracy and Sensitivity:

Built for precision, the DCRM System uses high-speed data acquisition and micro-ohm level resolution to detect even minute variations in contact resistance. This level of detail is essential for identifying issues like contact pitting, improper seatings, and high-resistance joints that could lead to future failures.

Comprehensive Testing Applications:

Suitable for a wide range of circuit breakers including SF₆, vacuum, and oil types, the DCRM System is indispensable for commissioning, maintenance, and condition-based monitoring. It supports testing of all voltage classes, from medium- to extra-high-voltage circuit breakers, across substations, utilities, and industrial facilities.

Compact and Field-Ready:

Engineered for field use, the DCRM System is compact, rugged, and portable, making it easy to deploy in challenging environments. It integrates seamlessly with other breaker test sets, offering enhanced diagnostic capability without added complexity.
