Description
Overview
GAOTek circuit impedance parameter tester is designed for efficient and accurate calibration of the primary measurement functions of the predominant Transformer Comprehensive Parameter Testers and Transformer No-Load Loss Parameter Testers available in the market. These primary measurement functions include no-load loss, load loss, no-load current, load current, impedance voltage, power, power factor, and frequency. The calibration device is equipped with a user interface tailored to the measurement features of the Transformer Comprehensive Parameter Tester. Users can conveniently preset relevant standard values directly, eliminating the need for additional manual conversion into corresponding current, voltage, angle values, and so on. This feature enhances the efficiency and reliability of the calibration process.
