HDGC3832 DC System Grounding Fault Analyzer

Product Details

1. The system has the function of measuring ground voltage. The instrument can measure the system's positive ground voltage, negative ground voltage, and system voltage, and can achieve a voltage monitoring range of 0-300V;

2. System insulation impedance measurement function, the instrument can measure the system's positive to ground insulation impedance and negative to ground insulation impedance, and can achieve measurements from 0 to 999K Ω;

3. Branch insulation impedance measurement function, the instrument measures the positive and negative to ground insulation impedance of each branch;

4. The branch grounding fault point positioning function can be achieved by the instrument, which can locate the grounding fault point of the branch grounding fault;

5. Current detection function, which can detect the leakage current of the tested circuit. When used in conjunction with a system analyzer, it can analyze the grounding impedance of the branch without sending a signal;

6. Direction display function: For branches tested with grounding indicators, the instrument will have directional arrows to indicate the relative direction between the grounding point and the searched grounding point, improving search efficiency;

7. The insulation index analysis function, when using the grounding function for testing, after detecting a branch, the detector will display the insulation index of that branch for user reference and analysis;

8. The waveform curve display function, when using a detector to detect the insulation condition of the tested branch, the display screen will show the current changes of the tested branch in the form of waveform curves, making it convenient for users to quickly and accurately locate the fault point.

Product Features

1、 High feasibility design
　　
HDGC3832 DC System Grounding Fault AnalyzerUsing an imported 16 bit microcontroller as the main system, the hardware design strictly follows the relevant standards of power and electromagnetic compatibility, and the feasibility of using multiple redundant devices and tested equipment internally.

2、 Material selection

The device uses a high-precision DC clamp meter as the signal acquisition unit, and the voltage sampling adopts a high-precision imported analog-to-digital conversion chip, ensuring accurate measurement of voltage and impedance;

3、 Humanized human-computer interaction interface

Both the "analyzer" and "detector" use LCD screens for users to view information; The operation is simple and fast, and when detecting different branches, only one press of the start button is needed to complete it; The test results are displayed intuitively and clearly, and can be presented to users in various display forms, including grounding status, waveform curve, insulation level, insulation impedance, leakage current size, direction information, etc.

4、 Intelligent detection and recognition system

The analyzer can automatically identify the system voltage level;

The analyzer can quickly display insulation impedance information after the system insulation impedance changes;

After synchronizing the information of the "detector" and "analyzer" once, it is not affected by the detection distance;

The "detector" can clamp a single power cord or multiple power cords to improve detection efficiency during testing;

After the "detector" completes the detection, if there is an insulation fault in the tested branch, it will determine the direction information of the fault point relative to the test point.

5、 Complete testing functions and fault handling capabilities

The "analyzer" and "detector" are equipped with wireless data transmission modules for communication, with complete testing functions and display information, and can handle various insulation fault situations in DC systems.
