■ functional features of capacitive current tester
▲ wider measurement range and faster test speed.
▲ support transformer neutral point different frequency signal injection method and compensation capacitor bank neutral point different frequency signal injection method.
▲ industrial color LCD with resolution of 320 × 240 dot matrix, readable in strong light.
▲ more friendly human-computer interface:
For some important operations and parameter settings, the prompt information and help description are displayed.
The display and printing of measurement results and related parameters are more detailed, which is convenient for users to analyze in the future.
When the PT connection mode is selected, the wiring schematic diagram under various Pt connection modes can be displayed, which is convenient for users to judge the site
PT connection mode and test line connection position.
▲ the status bar at the top of the screen displays the insertion status of USB flash disk in real time. When operating the unconnected equipment, the corresponding unconnected prompt information is displayed.
▲ measure and display the zero sequence 3U0 voltage value in real time, which is convenient for users to judge the working state of the system; In addition, if the zero sequence 3U0 voltage is found to be too high in the measurement project, the measurement process can be stopped automatically.
▲ with multiple zero sequence 3U0 overvoltage protection circuit, the output terminal of the tester can withstand AC100V and 50Hz without damage.
▲ built in full digital frequency conversion inverter power supply has the characteristics of accurate output frequency, adjustable output current, high output efficiency, small calorific value, small volume, light weight, long-time stable operation, etc.
▲ it has the function of output short-circuit protection.
▲ it has a real-time clock, which can display the current time and date in real time; The measurement results include the measurement date and time.
▲ the storage mode of measurement data is divided into local storage and USB flash disk storage, in which 150 pieces of measurement data can be stored in the local storage, and the local storage can be transferred to USB flash disk; The data stored in USB flash disk is in word format, which can be edited and printed directly on the computer.
▲ thermal printer printing function, fast and silent.
▲ small size, light weight and easy to carry.
