1Hardware

High-voltage Units: High-voltage coils, high-voltage voltage dividers, high-voltage switches, partial discharge coupling capacitors, coupling units, and partial discharge detectors.

Control Unit: The notebook unit is primarily used for controlling test programs, analyzing test data, and storing test data. External connections are high-voltage, with control switches for regulating high-voltage pressure. After grounding the system and internal connections are made, it is then connected to the cable being tested.

2Software

The software is primarily composed of:

The test analysis software is the main interface for user operations; it is controlled by a laptop. The software can perform the following actions:

-Define Test Objects

-Calibrate test circuit

-Pressure Test

-Test and save test data.

The browsing software is integrated within the system but can also be installed independently as per customer requests. The primary uses of the software include:

-Display and manage test data, generate test reports.

-Utilizing a pulse reflectometer to analyze test data.

-Generate database features.

The user interface is controlled by the mouse and keyboard. Each key on the screen is labeled with its corresponding function. Every active function key allows for the corresponding operation or directly enters the next operation interface. Click“EscPress the key to return to the system's starting interface.

The software's interface display and features can be summarized as follows:

Tested Cable: Define the parameters of the tested cable system.

Test Calibration: Initiate and execute calibration of the test circuit.

Field Diagnostics: Conducting tests and saving data to diagnose power cables on-site.

Review Report: Analyze data and generate test reports.
