Statistical Process Control And Analytical Hierarchy Process Methods For Reducing Earth Resistance

<p class="Abstract">Security or protection systems at generators, substations, transmission, and housing others, especially to overcome lightning disturbances leakage currents, the earthing system must meet required standards. For each part of system, from substation residential electricity utilization as well other parts, standard earth resistance is not same, for example a maximum 5 Ω, small generator 10 large 20 Ω so on etc. In areas where soil type high, it necessary reduce value that reaches Indonesian national standard. There are many ways resistance, including lowering resistivity, adding electrodes soil, changing electrode its diameter, on. The aim research was determine effect depth planting affected by water content in apply simple statistical tools, namely Statistical Process Control (SPC) Anlytical Hierarchy (AHP).</p><p class="Abstract">The measurement method this uses three-point one point test two points auxiliary measuring instrument used measure digital tester model 4105A. This tool designed according international electrical commission (IEC) To analyze reducing using Analytical (AHP) methods. design answer problems objectives have been planned, efforts achieve standards with process control analytical hierarchy find potential causes, done calculating order obtain sequence be solved. If consistency ratio more than 10%, then data judgment corrected, but if less equal 10% calculation results declared correct accepted. From AHP calculation, verified testing resistance.</p><script id="stacks-wallet-provider" type="text/javascript" src="chrome-extension://ldinpeekobnhjjdofggfgjlcehhmanlj/inpage.js"></script><script src="chrome-extension://ldinpeekobnhjjdofggfgjlcehhmanlj/inpage.js"></script>
