Feature:
1.Integrated structure,small size and light weight.The inside of the instrument is highly integrated.It integrates nearly a truck of equipment in the traditional measurement method in the integrated main box;it is the smallest and lightest among the same domestic products;it provides the simplest and most convenient method for testing method.
2.It is simple and convenient to connect to the power supply.All the measurement processes of the instrument only need to be connected to the 220V mains voltage,which solves the inconvenient connection of the 380V voltage on site in the existing measurement methods.
3.Super strong resistance to induced voltage.The instrument uses a unique patented technology(patent number:201020687669.X)anti-induction voltage circuit to ensure that the instrument can withstand higher induction voltage(anti-induction current can reach 40A)and can work normally under high induction voltage of 10,000 volts.
4.Frequency conversion technology,accurate measurement.Strong anti-interference ability.The instrument's built-in variable frequency power supply module provides the instrument's measurement output power,the frequency can be changed to 45Hz and 55Hz,and digital filtering technology is used to effectively avoid various industrial frequency interference signals on site,making the instrument achieve high Accurate,accurate and reliable measurement.
5.High-speed processor.Accurate and fast.The instrument uses a professional and fast digital signal processor as the processing core.Under the premise of ensuring the accuracy of the measurement data,it greatly improves its own computing and processing capabilities.
6.Simple operation.The external wiring is simple,the positive sequence impedance,the zero sequence impedance,the positive sequence capacitance,and the zero sequence capacitance at the test end only need to be connected to the down conductor of the tested circuit to complete all the measurements;it solves the existing test methods.The wiring switching is cumbersome,anti-interference,stability,accuracy,etc.problems;avoid the damage to the experimenter due to the induced voltage when changing the wiring.
7.Mass data storage.The instrument is equipped with a calendar chip and a large-capacity memory,which can save the test results in chronological order,and can view historical records at any time,and can print out.
8.Scientific and advanced data management.The instrument data can be exported via U disk,and the data can be viewed and managed on any PC and can be made into a work report.
9.Operational safety protection.The instrument is specially designed to detect the grounding function to judge whether the instrument is well grounded at the site.If the grounding is virtual or not connected,the instrument will automatically determine and prohibit operation by personnel to ensurepersonal safety and protect the use of the instrument.
10.Large LCD display with full touch.The operation is simple.The instrument is equipped with a high-end full-touch LCD display.The super-large display interface displays Chinese menus for all operation steps.Every step is very clear,and the operator can use it without additional professional training.The measurement of the whole process can be completed with one touch,which is a very ideal intelligent measuring equipment at presen
