The Construction and Efficiency Evaluation of Experimental Set on Underground Tubing Natee, Kumpiyaphol 31042 Tanes, Tanitteerapan 31043 Evaluation, power leak, short circuit, experimental set At present, most of the power system has been used to ground the more widely used because of the quality and stability of the electrical system. It can also reduce the severity of damage to the life and property in the event of a power leak, Short circuit. Therefore, if there is a set of experiments to ground. This will allow the student to understand the grounding in various systems. The research methodology is to design and construct the experimental set on underground tubing. There were 4 worksheets for the sample group. The samples of this research were 20 second year Electrical power division students who registered Electrical installation subject in course code: 3104-2201 .The result showed of the experimental set was in the highest level with average score of 4.507. The worksheets were in the high level with average score of 4.40. The efficiency evaluation of the experimental set with worksheets was in the highest level with 85 percentages. The circuit practicing was in the highest level 87 percentages. This result was higher than the standard criteria of 80/80. conference paper 2018-09 VoR application/pdf International Conference on Science, Technology & Education (ICSTE 2018) 157 160 https://miyazaki-u.repo.nii.ac.jp/record/5767/files/p157_icste2018.pdf http://hdl.handle.net/10458/6539 https://miyazaki-u.repo.nii.ac.jp/records/5767 eng
