The Digital Partial Discharge Test System is an integrated high-voltage testing solution featuring a 150 kV rated output voltage and 20 kVA rated capacity. It combines digital PD measurement technology with a variable-frequency power supply, a PD-free test transformer, a coupling capacitor, a voltage divider, and an intelligent control platform.
The system enables quantitative partial discharge measurement, signal visualization, calibration, test data recording, and report generation. Its integrated digital control functions support both manual and automatic test operation, helping improve the consistency and efficiency of insulation testing procedures.
The high-voltage test circuit, variable-frequency power supply, coupling components, and digital measurement unit are designed to work together. This integrated arrangement helps reduce the complexity of configuring separate instruments.
The power supply operates over a frequency range of 45–200Hz, allowing the test frequency to be adjusted according to the applicable testing procedure and equipment requirements.
The PD detector offers a stated sensitivity of 0.01pC and a measurement range from 0.1pC to 10,000nC. Multiple display modes support the observation of discharge signals and their phase-related patterns.
The system incorporates filtering and isolation components to help reduce interference from the power supply and external noise sources. Actual measurement performance depends on the test environment, grounding, wiring, and test object.
The digital detector supports data storage, waveform playback, printing, and report generation, helping users document test results for quality inspection and technical evaluation.
The system integrates the main power supply and measurement components into a coordinated test arrangement, helping operators carry out high-voltage testing in a more organized workflow.
The complete system has a rated output voltage of 150kV.
The stated detector sensitivity is 0.01pC. This should not be interpreted as the background PD level of the complete system.
The specification states ≤2pC at rated voltage under no-load conditions.
Yes. The specified operating frequency range is 45–200Hz.
The detector supports data storage, playback, printing, and report generation. Please confirm the required report format and data export workflow when configuring the system.
