CDF8200A Tan Delta Tester: Capacitance and Dissipation Factor Tester from China Factory Suppliers
The CDF8200A is a high-precision capacitance and dissipation factor (Tan Delta) tester for assessing transformers, bushings, insulating oil, and other power-system insulation. Its variable-frequency measurement method and digital filtering help limit power-frequency interference for accurate diagnostic readings.
The CDF8200A Capacitance and Dissipation Factor (Tan Delta) Tester is a precision diagnostic instrument designed for testing electrical power equipment. It combines a variable-frequency measurement method with digital filtering technology to reduce power-frequency interference and support accurate measurement of capacitance and dissipation factor across critical insulation components.
Designed for flexible testing and operation, the CDF8200A provides two cable connection modes for grounded and ungrounded test objects. The instrument automates the testing sequence, including voltage boosting, measurement, voltage reduction, and calculation. Wireless connectivity and onboard data-management functions give electrical engineers a practical tool for evaluating insulation condition and supporting power-system maintenance.
