Accurate Capacitance and Delta Measurements for High-Voltage Applications

In the realm of high-voltage electrical systems, precise capacitance measurement is critical for assessing equipment health and predicting potential failures. Professional Capacitance Delta Testers provide reliable solutions for measuring both capacitance values and dissipation factor (tan delta) - key parameters for evaluating the condition of electrical insulation in various power assets. These advanced instruments enable maintenance teams to identify deteriorating insulation before it leads to catastrophic failures, supporting predictive maintenance strategies that save both time and resources.

Meeting International Standards in High-Voltage Testing

Our Capacitance Delta Tester is designed to comply with relevant international standards for capacitance and dissipation factor measurements. The instrument aligns with testing methodologies consistent with IEC 60996, which provides methods for verifying accuracy of tan delta measurements applicable to capacitors :cite[10]. Additionally, the tester supports compliance with DL/T 2603-2023, the industry standard for relative dielectric loss factor and capacitance ratio live testing of capacitive equipment, applicable to 110kV and above voltage :cite[5]. This standards adherence ensures that your measurements are accurate, reliable, and recognized in the industry.

Advanced Sigma-Delta Measurement Technology

Modern Capacitance Delta Testers incorporate sophisticated sigma-delta measurement techniques for exceptional accuracy. This methodology, as described in patent documentation, involves applying a voltage to the measurable capacitance using a first switch, allowing the measurable capacitance to share charge with a passive network, and precisely monitoring charge levels against threshold values :cite[2]. This approach offers significant advantages including high noise immunity, resolution at relatively low frequencies, and effective implementation of high-precision measurements - all critical factors when testing high-voltage equipment in electrically noisy environments.
