ABSTRACT: The purpose of this study was experimental investigations and a study of the nature of the change in the main harmonic components of the current in the neutral working wire of a three-phase four-wire network with a voltage of 0.38 kV. The study of the amplitude-phase-frequency characteristics of currents flowing in an electric network with a predominant non-linear load is one of the most urgent tasks, the solution of which will increase the efficiency of electric power transmission and eliminate the negative consequences due to the current flow in a zero-working wire in the network at 0.38 kV. To study the effect of load changes on the amplitude-phase-frequency characteristics of currents in the linear and zero working wires at the input of the load node, measurements were carried out by certified electrical measuring instruments namely, the โ€œResource- UF2Mโ€ and โ€œHioki 3196โ€. keywords: current; fig; harmonic; load; load node; node; phase; power; wire; working cache: iiumej-1569.pdf plain text: iiumej-1569.txt item: #109 of 517 id: iiumej-157 author: chandavar, arunachala umesh title: PERFORMANCE DETERIORATION OF THERMOSIPHON SOLAR FLAT PLATE WATER HEATER DUE TO SCALING date: 2011-12-20 words: 4719 flesch: 57 summary: But in field, under such condition upper portion of most of the risers will be blocked and leads to negligible rise in tank water temperature.

The data losing concern becomes quite significant when it comes to reading data from sensors with nonlinear responses, however the fast development in both wired and wireless communication has been heralding an improvement of analog to digital conversion and even concerns of nonlinear errors are addressed so properly leading to final research products are achieving high level of accuracy conversion. keywords: 1kฯ‰; circuit; digital; engineering; fig; input; linear; output; pos; vol cache: iiumej-54.pdf plain text: iiumej-54.txt item: #386 of 517 id: iiumej-548 author: Mohiuddin, A K M; ADEYEMI, NABEEL A. title: LARGE EDDY SIMULATION FOR TRANSESTERIFICATION OF WASTE VEGETABLE OIL date: 2015-05-26 words: 11075 flesch: 65 summary: 3 5 2 p NN N D ๏ฐ ๏ด ๏ฒ ๏€ฝ IIUM Engineering Journal, Vol. 16, No. 1, 2015 Mohiuddin and Adeyemi 62 (a) (b) Fig. 6 (a) Plane cut (b) 3-D baffled STR with mixed-flow impeller using MRF.
