TL;DR: In this paper, a method for computing the electromagnetic force of a transformer iron core based on a finite element method is presented. But the method is limited to the case of a single transformer.

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, 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 paper, a multi-channel audible noise synchronous measurement system consisting of an audible noise measurement module, a host computer, a calculation module and an environment monitoring module is described.
