TL;DR: In this paper, a radio interference computing method for computing radio interference to an alternating-current high-voltage multi-loop electric transmission line was proposed, which includes dividing a super-highvoltage and an extra-high-volatile multilayer EHV line into a first line group and a second line group.

TL;DR: In this article, a differential method for determining the radio interference in an EHV (extra-high voltage) AC single-circuit power transmission line, and the method is used for determining a difference of radio interference between heavy rain and good weather.

TL;DR: In this article, the utility model relates to a multichannel power frequency magnetic field intensity synchronous measurement system, the system includes: the next machine, its and upper computer connection for carryout communication and data transmission with the host computer, the host computers, it links to each other with the next machines for send to the next Machine according to sampling interval and read data command, and the measured data who sends the nextmachine gathers, demonstration, storage, assay and warning, a plurality of power frequency magnetometer measuring unit, it is used for measuring the powerfrequency magnetic field

TL;DR: In this paper, the authors proposed a sound reduction measurement method for a paralleling-reactor sound shield, where the sound reduction is calculated through measurement of the sound intensity levels, sound intensity which is a vector and has directionality.

TL;DR: In this article, a method and system for determining an environment protection information transmission effect of a grid is presented. But the method is based on a hierarchical structure graph of transmission effect and a value of an importance degree of an influence on an environmental protection information propagation effect of the grid by each first-order index.
