Product Name: Automatic Capacitance Current Tester (Neutral Point Capacitance Method)
Product specifications: XSN-DR-PT02
Product introduction: XSN-DR-PT02 capacitance current tester, using a new hardware structure and faster ARM processor and AD converter, built-in brand new full digital inverter power supply, high efficiency, low heat, small size, Lightweight, more convenient to carry and field testing. The zero-sequence 3U0 voltage can be accurately measured at any time (including the measurement process), which is convenient for users to judge the working status of the system; and during the test, if the zero-sequence 3U0 voltage is too high, the measurement process can be automatically stopped. Industrial color LCD screen (readable under strong light), Chinese menu, human-computer interaction is more friendly, and it has functions such as U disk storage and data printing. Simple wiring, fast test speed, high test stability and high data accuracy, greatly reducing the labor intensity of testers and improving work efficiency.
Features:
1. The measurement range is wider and the test speed is faster;
2. Support 3PT connection mode, two 4PT connection modes, 1PT connection mode on-site capacitance current measurement;
3. Industrial-grade color LCD display, with a resolution of 320×240 dot matrix, readable under strong light;
4. The human-computer interaction interface is more friendly:
(1) For some important operations and parameter settings, prompt information and help instructions are displayed.
(2) The measurement results and related parameters are displayed and printed in more detail, which is convenient for users to analyze in the future.
(3) When the PT connection mode is selected, the wiring schematic diagrams under various PT connection modes can be displayed, which is convenient for users to distinguish the on-site PT connection mode and the connection position of the test line.
(4) The status bar at the top of the screen displays the status of the USB flash drive in real time. When operating an unconnected device, the corresponding unconnected prompt message is displayed.
5. Real-time measurement and display of the zero-sequence 3U0 voltage value, which is convenient for users to judge the working status of the system; and, if the zero-sequence 3U0 voltage is found to be too high in the measurement project, the measurement process can be automatically stopped;
6. With multiple zero sequence 3U0 overvoltage protection circuit, the output of the tester can withstand AC100V 50HZ voltage without damage;
7. Built-in full digital variable frequency inverter power supply, with the characteristics of accurate output frequency, adjustable output current, high output efficiency, small heat generation, small size, light weight, stable working for a long time, etc.;
8. With output short circuit protection function;
9. Equipped with a real-time clock, which can display the current time and date in real time; the measurement results include the measurement date and time;
10. The measurement data storage methods are divided into local storage and USB storage. The local storage can store 150 pieces of measurement data, and the local storage can be transferred to the USB; the storage data format of the USB is Word format, which can be edited directly on the computer print;
11. Thermal printer printing function, fast and silent;
12. Small size, light weight, easy to carry and use.
