The problem of electric power quality is a matter of changing the form of voltage, current or frequency that can cause failure of equipment, either utility equipment or consumer property. Components of household equipment there are many nonlinear loads, one of which Mixer. Even a load nonlinear current waveform and voltage is not sinusoidal.

INTRODUCTION Harmonic is a phenomenon generated from the operation of electrical loads that mostly result from nonlinear loads, which will form a wave of high frequency. The frequency is a multiple of its fundamental frequency of 50Hz so that the current waveform and the supposed voltage are pure sinusoidal will be defective due to harmonic distortion that occurs. Harmonics was usually defined as sine waves (currents and voltages) having integer frequency (integer) frequencies of their fundamental frequencies [1].
Maharani Putri, Pristisal Wibowo, Solly Aryza, Andysah Putera Utama Siahaan, Rusiadi http://www.iaeme.com/IJCIET/index.asp 868 editor@iaeme.com Electronic equipment such as Mixer is a non-linear load connected to an electrical utility causing an increase in harmonics in the electrical system that supplies it [2]. Total Harmonic Distortion (THD) of an electrical load can cause poor system power quality, low power factor, a distorted voltage waveform, increased system power loss, overheating of the transformer, inefficient use of electrical energy, and may affect the performance of other equipment using the power source [3]. The magnitude of the percentage of harmonics produced by Mixer not only gives an adverse impact to the mixer itself but also provides a bad influence on the system. Harmonics can damage the quality of rotation and also adversely affect the electric power equipment that is the value of RMS currents and higher voltage, the peak value (current) and higher voltage and frequency of the system down. While on the system, the influence of harmonics, among others: loading and the working transformer will increase weight, technical losses on the more extensive network, the use of electrical energy becomes inefficient, and the performance of other equipment was also disrupted [4]. 2. LITERATURE REVIEW Factors affecting the quality of electrical power include [2], [5]. 1. Electric consumers become increasingly aware of power quality issues such as voltage fluctuations, interruptions, and transients. Also, many governments in a country have revised their policies to further enhance the quality of power by established limits and standards. 1. The emphasis on overall power system efficiency has led to the use of high-efficiency devices, adjustable-speed motor drives and parallel capacitors to correct power factor and reduce losses. As a result, there is an increase in harmonic levels in power systems that threaten the operation, reliability, and security of the system. 2. Modern equipment loads use microprocessor-based controllers and power electronics devices that are more sensitive to changes in power quality. 3. Automation and efficiency depend on digital components requiring direct current supply. Since the power generated and transmitted is AC power, the AC power supply must be converted to DC first to be used by DC loads. Therefore, it will be much needed a converter that can further increase the harmonic level and can cause the fundamental wave distortion becomes more severe. A mixer is used for facilitating household work, especially to mix cookie dough matrials, bread, and so forth [6]. Design mixer reasonably modern. Has several components in it to support the optimal performance of a Mixer. The Mixers are one of the most modern types of household appliances used to lighten the workload of household chores. Mixer serves as a mixer or mixer of foodstuffs to make bread dough, cake, or the like. A mixer is only used as a household appliance, but it is not possible to use a mixer on a large scale as a home industry [7]. Mixer working principle is to convert electrical energy into mechanical energy by flowing electric current to switch speed selector switch and then rushed back to the driving force. The driving force present in the mixer is included in the induction motor of the wound rotor (wound rotor induction motor) [5]. To determineat at a value of Total Harmonic Distortion (THD) from the formulation of fourier series analysis for voltage and current in the function of time [8] = + ∑ + (1) = + ∑ + (2)
An Implementation of A Filter Design Passive LC In Reduce A Current Harmonisa http://www.iaeme.com/IJCIET/index.asp 869 editor@iaeme.com For the RMS voltage and current value of the sinusoidal wave we can calculate the wave peak value divided by √2 and fourier for the voltage and current shown Equation (5 and 6) [9]: = + ∑ √ (3) = + ∑ ! √ (4) The value of Total Harmonic Distortion (THD) for voltage and current is shown in Equations (7 and 8) ie: "# $ % = ∑ & √' ' ( )' &* √' = +∑ '( )' * (5) So the current RMS to THDI becomes: = , -1 + "#$! / (6) Table 1 Standard harmonic current for class D equipment 3. METHODOLOGY OF RESEARCH. The method used in this study is to perform Measurement and retrieval of data performed directly. Measurement and retrieval of data are done directly to the field by using a measuring tool called Power Quality Analyzer. Data communication from Power Quality Analyzer to the computer is done via USB. This data communication packet is displayed in list and graph form directly, and the data can be stored on the computer.
