Fully Automatic Capacitance And Inductance Tester with USB Interface
Product Description
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.
