A capacitance and tan delta test system measures insulation health in electrical equipment by analyzing capacitance and dielectric dissipation factor (tan delta). Wrindu, a leading China-based manufacturer and OEM factory, offers advanced, reliable test systems designed for wholesale and custom supply, ensuring accurate, safe, and efficient diagnostics worldwide.
What Is the Purpose of a Capacitance and Tan Delta Test System?
A capacitance and tan delta test system evaluates insulation condition in transformers, cables, and capacitors by measuring capacitance and dielectric losses. It detects moisture, aging, and contamination in insulation materials, preventing faults. Wrindu tailors these systems to meet rigorous B2B testing needs across China and global markets.
This system is essential for proactive maintenance and accurate insulation condition assessment, minimizing failures and enhancing asset longevity.
How Does a Capacitance and Tan Delta Test System Work?
It applies an AC voltage to the insulation and measures resulting current to determine capacitance and tan delta values. Capacitance reflects insulation capacity, and tan delta shows losses due to defects. Wrindu’s systems feature precision voltage control and sensitive detection circuits, delivering reliable diagnostics in factory and field settings.
Advanced electronics and software allow detailed analysis, data logging, and fault trend tracking to optimize maintenance strategies.
