1Hardware

High-voltage Units: High-voltage coils, high-voltage voltage dividers, high-voltage switches, partial discharge couplers, 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 making internal connections, it is then connected to the cable being tested.

2Software

The main components of the software are as follows:

Test analysis software serves as the main interface for user operations; the software is controlled by a laptop. The software is capable of performing the following functions:

-Define Test Objects

-Calibrate test circuit

-Pressure Test

-Test and save test data.

The browsing software is integrated into the system but can also be installed independently as per customer requirements. The primary uses of the software are as follows:

-Display and manage test data, generate test reports.

-Utilize 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 is capable of performing the respective function or directly accessing the next operation interface. Click“EscPress the key to return to the system's starting interface.

The interface display and functionalities of the software 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.
