Fully Automatic Capacitance And Inductance Tester with USB Interface
In the daily operation and maintenance of power systems, the regular testing of parallel capacitor banks is a crucial step in ensuring the reactive power compensation capability of the power grid. However, traditional testing methods have long faced a thorny problem: the connection lines of the capacitor bank must be disconnected before individual capacitor measurements can be performed. This operation not only involves a huge workload and reduces maintenance efficiency, but also creates hidden dangers such as bushing leakage and equipment damage due to repeated disassembly and reassembly.
GDRG-H fully automatic capacitance and inductance tester was developed precisely to solve this pain point in the field.
Test subject:
High-voltage parallel capacitor banks
Series reactors and damping reactors
Filter branch capacitors and reactors

Advantages：
Onboard Storage – Saves up to 400 complete test data sets, including timestamps, voltage level settings, equivalent modes, and all measurement parameters.
USB Export – Data is directly transferred to the accompanying software via a standard USB cable connected to a PC, requiring no additional reading device.
Excel Format Reports – The accompanying software is a portable, installation-free version compatible with all Windows operating systems. Exported files are automatically named in "CDATA_YearMonthDay_HourMinuteSecond_SerialNumber.xlsx" (capacitor) or "IDATA_YearMonthDay_HourMinuteSecond_SerialNumber.xlsx" (inductor) format, allowing for direct archiving or embedding in test reports.
Local Data Sovereignty – All records are stored only on the instrument and the user's PC, with no forced cloud uploads, complying with power industry data security practices.
