Analisis Trafo Scott Mengatasi Penurunan Kapasitas Daya Akibat Distorsi Harmonik

This study aims to determine Scott's transformer size which is suitable for use in the electrical system of the 4th Floor, F&G Building, Herry Hartanto Building, Faculty of Industrial Technology, Trisakti University. found in the electrical system. The research used is a quantitative and qualitative approach. This quantitative study was used because the researchers wanted to know and calculate the magnitude of the harmonics that occurred on the 4th Floor, F&G Building, Herry Hartanto, Faculty of Industrial Technology, Trisakti University and designed a single passive tuned filter parameter. Whereas qualitative research was used to analyze the comparison between before and after the installation of Scott transformers and their effect on the harmonic value of the 4th Floor, F&G Building, Herry Hartanto, Faculty of Industrial Technology, Trisakti University. The results of this study are the simulation results of the Scott relationship transformer installation can eliminate voltage harmonics so that the electric waves formed into pure sine and Scott transformer connection installation can reduce the highest THD value in panel A, Floor 4, Building F&G, Herry Hartanto Building, Faculty of Technology Industry, Trisakti University from 11.45% to 1.28x10-5%

Electrodynamics from Thomson and Maxwell to Hertz

This article examines developments in the field of electrodynamics from William Thomson and James Clerk Maxwell to Heinrich Hertz. It begins with a discussion of Michael Faraday’s work, focusing on his discovery of what was later termed ‘dielectric capacity’ and his role in the birth of field theory. It then considers Thomson’s unification of Faraday’s understanding of both electro- and magnetostatics with energy conservation, along with Maxwell’s extension of Thomson’s structure to cover electrodynamics, which for the first time brought to the fore issues concerning the electric current. It also describes Maxwellian electrodynamics and electromagnetic theory, Hermann Helmholtz’s development of a different form of electrodynamics, and Hertz’s work on electric waves.

The Sound of Thought

From a physical point of view, language is made of waves: acoustic waves (outside us) and electric waves (inside us). How similar are these two types of waves? By exploiting awake surgery procedures a crucial experiment is described confronting these two types of waves when a patient reads a linguistic expression aloud or silently. The surprising result is that the two electric waves are very similar even in non acoustic areas opening the possibility to read the linguistic thought directly from the brain.
