The use of a Water Pump at the initial start is the use of electricity with a large capacity which sometimes faces various kinds of efficiency problems. These problems include an increase in current that occurs in the channel by improving the quality of electric power, especially in the electrical system in the area of the use of the Water Pump, which is expected to be able to improve the quality of electric power. The purpose of the research was to design an inverter starting energy saver as an effort to improve power quality for electricity savings, electric power efficiency in water pumps. This improvement is also expected to be able to reduce the cost of using electricity bills, especially in the use of water pumps. To be able to carry out the improvement of the quality of the electric power, it is necessary to calculate the active power and apparent power when the water pump is used. After performing these calculations, the installation of the inverter starting circuit saver electricity will be used. By carrying out these steps by installing a series of inverters that can improve the quality of electrical power. And by using the inverter circuit starting Energy saver, it is clear that it produces an active power efficiency value of 82% of the active power before using the 272 Watt inverter circuit and active power after using the 223.9 Watt inverter circuit, and also produces an apparent power efficiency value of 83% before using the circuit. inverter 275.18 VA and apparent power after using the inverter circuit 227.94 VA

<p>The use of electricity with large capacity sometimes faces various kinds of problems. These problems include network losses and voltage drops that occur in the channel. Improvement of electric power factor at PT. Karya Toha Putra is expected to improve the quality of electric power. This improvement is also expected to reduce the cost of electricity bills at PT. Karya Toha Putra. To be able to implement improvements in the quality of the electric power, it is necessary to calculate the reactive power compensated. In this case the power factor to be achieved is 0.95. After doing these calculations, the determination of the capacitor value will be used. By doing these stages, it is expected that the installation of capacitor banks can improve the quality of electric power. Bank capacitors are collections of capacitors used to provide reactive power compensation to improve the electrical power factor. From the results of the study showed that the amount of compensation needed to improve the power factor at PT.

In this paper we present a method to determine the power efficiency of ultraviolet (UV) disinfection plants and apply this to low pressure plants for drinking water. In UV disinfection plants the water flow is regulated to ensure that microorganisms receive the necessary fluence for inactivation while passing through. The flow depends on the UV transmission (UVT) of the water. The lower the UVT of the water is, the less water may flow through the plant. UV irradiance is produced by lamps that consume, together with other components, electrical power and entail running costs. The power efficiency – electrical power versus disinfected volume – of a plant has therefore an important impact. Applying this method to different UV plants that are on the market shows that electric power of at least 5.3 Wh is necessary to disinfect 1 m3 of water possessing a UVT of 80% (100 mm), 8 Wh at 50% and 22 Wh at 10%. Further we found that ineffective design or a wrong selection of a plant may enhance these values by a factor of up to 7. This method enables not only the calculation of the power efficiency but also the decision for a certain plant type.

Quality Deviation

The use of solar modules to meet the needs of everyday life is something interesting to use. Harmonics is a phenomenon of power quality deviation that can distort voltage and current waveforms. In this experiment, a simple inverter with 1000 W capability will be used, then will be loaded with water pumps and other household appliances. The method used is to measure the power factor and harmonics generated by using a measuring device. In this process needs to be assessed and will be seen using the ability of the inverter and the quality of the electric power generated in this solar power generation system. Based on the results of measurements and calculations on a water pump with  a power of 680 W and 1 incandescent lamp with a power of 60 Watts, the value of the power factor generated is 0.95 while the total harmonic voltage distortion (THDv) value is when the water pump load is THDv 1.9 % and at THDv incandescent lamps 1.6%.

The article deals with the problem of unbalance of currents and voltages of communal utilities and the degree of correspondence of existing solutions to the level of informatization. The classification and structure of measures to reduce asymmetry, existing means and devices for balancing are considered. Particular attention is paid to the switching method of asymmetry’s correction. The advantages of this method in comparison with the others are indicated in the article. It is established that at present the realization of this method is associated with considerable labor costs for personnel with minimal automation of the process. A comparative analysis of devices based on the switching method of balancing with other devices is performed. Several examples of devices are given. It was found out that devices, the principle of operation of which is based on the switching method, require significantly less investment than other devices. The analysis of the correspondence between the level of automation of the balancing process and the capabilities of automated systems for data collection and processing is carried out. Several devices of automated systems for monitoring and accounting of electric power and automated devices for monitoring the quality of electricity were considered. It was found out that automated systems for monitoring and accounting of electric power, in spite of lower accuracy of measurements, have an advantage over automated systems for monitoring the quality of electric power in their greater prevalence. It is concluded that with the existing level of equipping networks with such systems, information on asymmetry can be obtained with the necessary accuracy and without additional capital investments. The conclusion is made that the problem is topical and because of the analysis of existing methods for reducing asymmetry, the task is formulated of developing new methods, the realization of which is possible with the help of an automated advisory system.
