Contact Resistance Measurement

Contact Resistance Measurement assesses the quality and integrity of electrical contacts within switchgear components. Accurate measurement ensures low resistance at connections, preventing overheating, power loss, and equipment failure. Essential for circuit breakers, busbars, and switch contacts to maintain optimal performance and electrical safety.

Precise Resistance Testing

Measures micro-ohm level resistance of contacts to identify wear, corrosion, or oxidation.

Applicable to Various Switchgear Types

Includes vacuum, SF6, air-insulated switchgear, and motorized circuit breakers.

Preventive Maintenance Tool

Detects potential faults early to reduce downtime and avoid catastrophic failures.

Detailed Reporting & Recommendations

Provides comprehensive test reports with trend analysis and corrective maintenance suggestions.
