Overhead Transmission Line Electric Parameter Test System High Voltage Power Line Fault Tester

Inter-frequency line parameter tester is a high-precision testing instrument for field testing the power frequency parameters of various high-voltage transmission lines (overhead, cable and overhead cable mixture). The instrument is integrated structure, built-in frequency conversion power module, adjustable voltage output power supply. The frequency can be changed to 45H and 55Hz. Digital filtering technology is adopted to avoid the interference of power frequency electric field to test, and fundamentally solve the problem of accurate measurement under strong electric field interference. At the same time, it is suitable for generator power supply detection after all power failure.

1.Integrated structure, small size, light weight
The instrument is highly integrated, integrating nearly a truckload of equipment in the traditional measurement method into the integrated main engine box. At present, it is the smallest and lightest in domestic equivalent products. It provides a simple and convenient test means for the test.
2.Simply and conbenient to connect power supply
All the measuring process of the instrument only needs to be connected to the 220V voltage of the mains, which solves the inconvenient trouble of the on-site 380V voltage access in the existing measurement method.
3.Super anti-induction voltage capacity
The instrument uses unique patented technology anti-induction voltage circuit, to ensure that the instrument can withstand higher induction voltage (anti-induction current can reach 60A), can work normally under 30,000 V of high induction voltage.
4.Direct measure induced voltage and induced current
The instrument uses unique patented technology anti-induction voltage circuit, to ensure that the instrument can withstand higher induction voltage, because of this, the instrument can directly measure the induction voltage and induction current, and can judge whether the instrument can measure the line.
5.Frequency conversion technology, accurate measurement
Strong anti-interference ability, by the instrument internal frequency conversion power supply module to provide instrument measurement output power, frequency can be 45Hz and 55Hz, and the use of digital filtering technology, effectively avoid the field of various power frequency interference signals, so that the instrument to achieve high precision, accurate and reliable measurement.
6.High-speed processor
Accurate and fast, the instrument adopts professional fast digital signal processor as the processing core, under the premise of ensuring the accuracy of the measurement data, greatly improves the operation and processing capacity of the instrument itself.
7.Simple operation
External wiring is simple, positive sequence impedance, zero sequence impedance, positive sequence capacitance, zero sequence capacitance at the test end only need to access the lead line of the line under test to complete all measurement; It solves the problems existing in the existing testing methods, such as complicated wiring switching, anti-interference, stability, accuracy, etc. Avoid damage to experimental personnel caused by induced voltage when wiring is changed.
8.Mass data storage technique
The instrument is equipped with a calendar chip and large capacity memory, which can store the test results in chronological order, and can view the historical records at any time, and can be printed out.
9.Advanced data management
The instrument data can be exported through THE U disk, and the data can be viewed and managed on any PC and made into a work report.
10.Full touch ultra large LCD display
The operation is simple, the instrument is equipped with high-end full touch LCD screen, large display interface all operation steps Chinese menu display, every step is very clear, operators do not need additional professional training can use. The whole process can be measured with a simple touch. It is an ideal intelligent measuring device at present.
11.Operation safety protection
The instrument is specially designed to detect the function of grounding, to judge whether the instrument is properly grounded on site. If the grounding is false or not connected, the instrument will automatically judge, prohibit the use of personnel operation, to ensure personal safety, and protect the use of the instrument.
