The effect of Harmonic impact on electric power system is very wide, one of which is can cause mulfunction on power system operation. One of the factors that can generate harmonics is the use of linear loads, among others, induction motors and the use of power electronics equipment. To Lower THD Voltage On Electric Power System In Electric Room 27 On Finish Mill Tuban IV PT. Semen Indonesia (Persero) Tbk uses passive filter with sigle tuned and high pass type. This rearch concludes that the use of passive filters on electric room 27 can reduce THD Volume by an average of 1.14% for Group Expenses 547 and an average of 1.15% for Group Expenses 548 and an average of 0.41% for Group Packer Expense. However, the decrease of THD voltage is less effective, because there is THD above 5% in group 547 an 548.

Abstrak — Alternator salah satu komponen yang sangat penting pada kendaraan. Alternator mobil ini mengeluarkan tenaga listrik AC dengan memanfaatkan putaran tenaga angin kemudian diubah menjadi tenaga listrik DC sebelum disuplay ke akumulator. Oleh karena itu tidak diperlukan tenaga operator untuk mengoperasikan kerja dari alternator tersebut. Tegangan yang di hasilkan sel pada sebuah accu biasa adalah 2V/sel. Tetapi sebetulnya tegangan kerjanya adalah lebih tinggi. Seperti diketahui, guna mengalirkan arus melalui sebuah accu, tegangan alternatornya harus lebih tinggi dari tegangan accu itu sendiri. Dipihak lain harus dijaga supaya tegangan itu tidak terlalu tinggi guna mencegah mendidihnya (gas) dari accu. Sebagai tegangan pengatur yang aman pada 200 C harus dipertahankan 2,35 V/sel sampai 2,4 V/sel. Bagi accu 12V hal itu berarti tegangan kerja sebesar 14,1 V-14,4 V.Kata kunci: Valve Alternator, Accu, TeganganAbstract — Alternator is a very important component. The car alternator issued AC electric power by utilizing wind power rotation is then converted into DC electrical power supplied to the accumulator before. Therefore, it is not required of operators to operate the working of the alternator. The voltage generated cells in a normal battery is 2V / cell. But actually working voltage is higher. As is known, in order to drain current through a battery, alternator voltage should be higher than the voltage of the batteries themselves. On the other hand must be maintained so that the voltage is not too high to prevent boiling of (gas) from the batteries. As the voltage regulator safe at 200 ° C should be maintained to 2.35 V / cell until 2.4 V / cell. For 12V battery it means that the working voltage of 14.1 V-14,Keywords: Alternator, accumulator, Voltage

The unbalanced loads used is common to electricity consumers, and common at the field. Many of its 20 KV Distribution Depots are installed to serve users of electrical energy, and the lack of management of kWH Meter setup settings based on profiles of each customer is different from each other, as well as the use of varying electrical energy in each customer causing uneven distribution of the Distribution Tray. This raises another problem, namely the loss of electrical energy due to imbalance Electrical load in each phasa. Therefore, the authors analyze the effect of load imbalance on the age of electrical equipment. Furthermore, applying appropriate measures to balance the load of the transformer, so that consumers are expected to better understand the consequences of Electrical Load imbalance.

The power transformer at the substation serves to deliver power from high voltage to low voltage or vice versa. In the transformer section there is a neutral grounding resistance mounted serially with the secondary neutral on the transformer before connecting to ground / ground that serves to minimize the fault current. One of the disadvantages of the NGR grounding system is when there is a short-circuit one-phase interruption to the ground, the soil disturbance current may be larger than the NGR value limit used. This can cause damage to NGR and other equipment. This study discusses more current fl ows in NGR under normal circumstances with cable channel length 28,215,244 feet and at a 20 kV voltage of ground capacitance with manual calculations obtained Ico = 1.167 A and in case of one-phase disturbance to the ground the greater the current Ig = 4.61 A. To prevent the enlargement of short circuit current one phase of this phase, then the measurement of neutral grounding resistance.

With the rapid power needs of the people living in urban and rural areas will not affect either the quality of the voltage in the value of PLN service under specified standards. Factors affecting namely the existence of the impedance on the channel, there will be a voltage drop, which is the product of current voltage with an impedance of electrical power distribution equipment. The greater the resistance of the conductor of the price, the greater the voltage drop across the electric power system. It is necessary to repair the voltage drop at the end of the received voltage can be done by raising the voltage of the tip tell .. To solve the voltage drop voltage regulator can be used on condition that the nominal voltage of 20 kV medium voltage distribution (phases) or 11.57 kV (-phase neutral) phase-neutral .Batas minimal service = -10% of nominal voltage = 10.41 kV or at 18 kV (phases). Limit the maximum phase-neutral service = + 5% of nominal voltage = 12.15 kV or at 21 kV (phases).

As a company that promises business in the field of electricity. PT. PLN (Persero) Rayon Tanah Jawa strives to reduce the transformer that is experiencing more burden. Overload on the transformer will cause damage to the transformer. Therefore, efforts are needed to install a fixed transformer to minimize the occurrence of overload. Reduced voltage falling from base to end is a positive impact on the installation of a transformer because the length of the network decreases. This research aims to determine the percentage of load and voltage drop during the transformer before insertion with after insertion. Data that needs to be considered for conducting transformer insertion is the measurement of transformer load and base voltage measurement with the tip. From the calculation results obtained that the transformer load value measured from 95.99% to 64.54% while the voltage drop at the end of the network from 190.5 Volt to 206.8 Volt.Keywords: Insert Transformer, Overload, Falling Voltage
