The integrated partial discharge location system is primarily used for medium-voltage cable partial discharge diagnostics. The system's test frequency is20HzUp to several hundred hertz of damping AC voltageDACThe damping AC voltage during the system's testing phase can reach high levels.30kVOur company integrates advanced system hardware and software for diagnostics, featuring a comprehensive software system.VLFPlease provide the Chinese content that needs to be translated into American English.DACThe on-site voltage tests, which integrate non-destructive partial discharge testing and dielectric loss measurements, represent a fundamental and effective testing method for the operation, maintenance, and repair of cables. This method is applicable to nearly all medium-voltage cable types, such as...XPLEAnd the necessary test voltages for cables with paper insulation, as well as diagnostic tools.

Damping AC voltage as high as can be reached during the system testing process30kV, and utilize advanced system hardware and software for diagnostics, including:

-New transistor technology and laser control technologies, such as high-voltage transistor switches.

-Electronic components, digital signal processing, including high-voltage crystal switches, high-voltage sources.

-Digital Signal Processors and Filters

1Hardware

High-voltage Units: High-voltage coils, high-voltage voltage dividers, high-voltage switches, partial discharge capacitive 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 made with high voltage, and the control switches are used to control the high-voltage pressure. After grounding the system and making internal connections, it is then connected to the cable under test.

2Software

The main components of the software are as follows:

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

-Define the test object.

-Calibrate test circuit

-Pressure Test

-Test and save test data.

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

-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 is capable of performing the associated function or directly entering the next operation interface. Click“EscPressing the key will 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: Perform testing and data storage to diagnose power cables.

Review Report: Analyze data and generate test reports.
