TECHNICAL STUDENTTOPIC MINIMISING VOLTAGE DIFFERENCES Short guide to working out cable sizes In the first of two articles‚ Bill Allan looks at the correct method in cross-sectional work‚ a job that requires a head for calculations and a steady hand Ask any electrician about the required cross-sectional areas of cables for standard circuits and the answer you receive will probably be along the lines of: “1mm2 or 1.5 mm2 for lighting circuits and 2.5 mm2 for socket-outlet circuits.” Indeed these

Project Model No: 164 ABSTRACT PRECISE KILLOMETER CALCULATION BY UNDERGROUND CABLE FAULT DETECTOR The project uses the simple concept of OHMs law where a low DC voltage is applied at the feeder end through a series resistor. The current would vary depending upon the length of fault of the cable in case there is a short circuit of LL or 3L or LG etc. The series resistor voltage drop changes accordingly which is then fed to an ADC to develop precise digital data which the programmed microcontroller

Five Star and Amtech Travis Huggard: G00059703 Professor: R. Todd Kane Grantham University Five Star and Amtech When deciding which type of culture was dominant at either 5 Star or Amtech‚ I had to look at what type of culture their presidents represented. For example‚ the president of 5 Star‚ John Tyler “believed that 5 Star was the far superior company‚ had effective managers‚ had clear responsibilities and jobs” (Daft‚ 2001). On the other hand‚ the president of Amtech‚ Jim Rawls‚ did not believe

INTRODUCTION Anthropometry is the study of the shape and size of the human body. As roebuck defines it – “the science of measurement and the art of application that establishes the physical geometry‚ mass properties and strength capabilities of the human body.” The name derives from anthropos meaning human and metrikos meaning of or pertaining to measuring. According to Pheasant(1996) anthropometry’s historical antecedents date back to Renaissance. He cites works such as Albert Durer’s (1471-1525)
