This project deals with the application of microcontroller used for measuring the Q-factor of band pass filter. The procedure starts from the design creation and improvement of Q-factor and bandwidth of the filter. Solving the circuit filter frequency requirement the band must pass the filter. An instrument is necessary in the design of filtered frequency that shows the cut off at the rise edge and down edge searching the bandwidth and Q-factor of the filter. Finally the monitor will show all the values of every detail.

This article presents the energy conservation of the wood furniture factory in Samutprakarn province by using engineering management technique. The electrical energy of 7408000 kWh per year or 25988055 Bath per year is mainly used in the processes including a heating energy system that is derived from wood scrap. After detailed audit it was found that 8 measures have a potential to improve energy efficiency. 7 measures for electrical energy can reduce the energy of 479837.60 kWh per year and the rest decreases heating energy of 120297.15 MJ/Year or saving the scrap of 9.4 tons per year. In order to assess economic possibility all measure also were considered. The result showed that it was worth to investment. In addition specific energy consumption (SEC) can be improved from 0.57 kWh/ft3 to 0.54 kWh/ft3 or diminishing of 5.26 %

This paper presents a remote control device adapted to control the power station equipment. This system is a part of the control and collecting data system. It is used to control the operation of the circuit breaker in the power station and to reduce the transfer of load quickly and easily. It is tested with an open - closed circuit of the power system control centers 10 of which have no error (100 percent) As for the amount of electricity It is tested by the meter reading of this controller compared to the actual payment system to a percentage error. It was found that the reading of zero percent power control error was less than the percentage error of reading from the meter front control panel. The system can record the amount of power to bring information to plan the expansion of the distribution system in the future. However some power station equipments to be installed such as unlocked - chopping blade switches whose functions cannot be controlled.

This research presented the details of design and constructions of tesla transformer for testing insulator. The out put of the tesla transformer has a rate of 120 kV and 120 kHz. Tesla transformer consisted of primary coil and secondary coil which is wound on a PVC insulating chamber and use air insulation in part of coaxial. The Rotary Gap is rotated eletrode which use for increasing efficiency of voltage generation. This paper presented the details of design and constructions are explained. And compare the tesla Transformer reproduce which is created the voltage at 120 kV and frequency 120 kHz for used in HighVoltage Laboratory Faculty of Engineering Rajamangala University of Technology Para Nakhon.
