This is a survey research. Its objective was an attempt to analyze the problems and utilization of instructional innovations of lecturers at the Faculty of Industrial Education Rajamangala University of Technology Phra Nakhon. The sample group consists of 38 lecturers from four departments. The questionnaires were provided as the research tool to collect data. Statistical analysis was applied by using percentage mean standard deviation t-test and F-test technique. The research results were that the lecturers were different in gender age and educational background but problems in using instructional innovation were at the moderate level. The most internal important problematic factor was their attitude toward the utilization of innovation. The most external important problematic factor was lack of financial supporting on the production of instructional innovation. Lectures under the Civil Engineering and Mechanical Engineering Department had problems in difficulty of using instructional innovation more than those of the Electrical Engineering Department.

Today Transformers 300 MVA in use of Electricity Generating Authority of Thailand Metropolitan Electricity Authority and private companies were active in the power transmission system. To increase the efficiency and security of the countrys energy systems after using it for a while it requires annual maintenance such as checking and testing of various power. However the problem of leakage of transformer oil is a common problem and affects the environment. This is caused by the malfunctioning equipments which affect the performance of the transformer. The solution will require more time and money. We have to find a way to fix the leak of the transformer oil by reducing the amount of oil and the temperature of the oil in order to reduce the time and cost -savings.HoweveriIt does not affect the performance of the transformer
