DC system insulation faults, DC mutual faults and AC power failures are faults that are prone to occur and are harmful to the power system, and endanger the normal operation of the power system.
Product Features:-
● High reliability design
The device adopts imported 32-bit microcontroller as the main system, and the hardware design strictly follows the power and electromagnetic compatibility related standards. The internal redundancy mode is adopted to ensure the reliability of the device and the device under test.
● Precision material selection
The device adopts high-precision collector as the signal acquisition unit, and the voltage sampling adopts high-precision imported analog-digital conversion chip, voltage and impedance are measured accurately;
● Humanized human-computer interaction interface
Both the analyzer and the detector use a TFT liquid crystal display for users to view information;
The operation is simple and fast, and when the detection of different branches is realized, only one start button can be completed;
The test results are straightforward and the test results can be presented to the user in a variety of display formats, including grounding or not waveform, insulation levels, insulation resistance, leakage current, and direction information.
● Intelligent detection and recognition system
The analyzer automatically recognizes the system voltage level;
The analyzer can determine the ring fault category;
After the detector and analyzer information are synchronized once, it will not affected by the detection distance;
When the detector is inspecting, the collector can clamp a single power cord or clamp multiple power cords to improve detection efficiency;
After the detector test is completed, if the tested branch has a ring network or insulation fault, the direction information of the fault point relative to the test point is determined.
● Complete testing function and ability to handle faults
The wireless data transmission module is built in between the analyzer and the detector for communication. The test function and display information are complete, and can deal with various ring networks and insulation faults in the DC system.
The analyzer has a variety of combined working mode by selecting functions of “Amplitude Modulation”, “Waveform” and “Mode”, which can adapt to various complex application environments.
● High security
The device adopts the micro-amplitude detection signal and the high-resolution DC detection collector to realize fault detection and positioning, and has no influence on the DC system.
