This abstract discussed the implementation of speech recognition applications to control the on-off electrical device of speech. The work is divided into two modes. Offline mode and online mode. To use voice commands to turn on-off electrical device. Which the words sound as a statement. The speech sounds in offline mode is saved in SOPARE voice and speech mode are saved online in Google Assistant via the microphone. Then process the Raspberry pi 3 board to send data to the wireless transceiver module to control the power on-off. From testing the control system for opening and closing electrical devices with sound it was found that the sound test in the offline mode of the power-on-off control system with sound the accuracy of 96 percent of the voice command and the accuracy of the lamp according to the voice command spoken 100 percent accuracy. Sound tests in the online mode of the power-on-off control system with sound the accuracy of 8 7 percent voice commands and the accuracy of the lamp according to the voice command spoken 100 percent accuracy. The power-on-off control system with sound. Can be used to effectively control the opening and closing of electrical equipment. Only the user speaks the voice commands as needed and can immediately turn on-off the electrical equipment. Helps reduce steps and shorten the time of use making it more convenient

This research presents the development of a low rate and low power consumption low rate wireless network. Low rate wireless networks are cheap and comprised of a small fully autonomous processing communication and remote control devices. The purpose of this study is to develop the system for remote wireless lighting system. They will work with wireless network system (WNS). WNS has been restricted power supply communication distance and low computing power. But they will work with network in vast area send and receive raw data from each network node. It has the ability to cooperatively collect data and retransmit in order to process or alert. The step of the experiment is creating main node and sub node in lighting area and transmission of control data between them with less electrical wiring. When wireless node not receiving or transmitting data the module can be switched into the sleep mode low power consumption mode. We can reduce the use of electrical wiring; insulated insulation material or other that related to and include energy too.

HV power distribution system circuit breaker are important devices in substations. Such as Malfunction or deterioration of equipment with in the substation will directing impact on the stability of the power distribution system and affect the reliability of the system. In addition this means that it is necessary to assess the actual condition of the proper condition-based operation and maintenance. Thus this thesis presents condition assessment procedure for equipment by using technical information visual inspection by Weighted Scoring Method. Weighting technique is used to determine important weight testing methods of devices by using Analytic Hierarchy Process (AHP). Testing methods for circuit breaker are such as visual inspection contact timing test. Scoring technique is divided into 1-3 levels by classifying on actual evaluate equipment consisting of consisting of good moderate bad. This thesis proposes a software development in order to organize the database and calculate the analysis of the condition of equipment in 5 HV substations. The evaluation results will be divided into 3 levels good medium and bad condition. According to the evaluation level the maintenance types are separated into 1) regular maintenance 2) increase the frequency of maintenance and monitoring of the test 3) equipment must be improved urgently. Finally abnormal incidents of equipment and cost of HV equipment maintenance can be reduced in effective way.
