| Summary: | One of the characteristics of power quality (power quality) in the Steady state conditions are harmonisa (Harmonic). Harmonisa consists of; harmonisa flow distortion (THDi) and voltage distortion harmonisa (THDv). Harmonisa flow distortion (THDi) occur as a result of the burden that is not linear (non-linear) on the users of electricity, for example, metal smelting (arc furnaces), the user automatic / variable speed drive (ASD), and others. Harmonisa flow through the Impedance berharmonisa will cause the load voltage. Most of the current and voltage distortion is caused by the customer as a user of electricity.<p> Harmonisa flow distortion (THDi) caused customers metal smelting (arc furnaces) can cause a potential loss in the electric power company (utility), among others: a) Improve the distribution network between the decrease 13,146.90 kWh (0.017%) up to 25,211, 54 kWh (0.032%) per year. b) Improve the decrease in the power transformer between 87,651.82 kWh (0.111%) up to 169,797.29 kWh (0.215%) per year. c) Lower power transformer capable of power between 3.35% to 6.15%. d) The age of power transformer operating between 2.09 years to 9.04 years. finasial can cause the potential loss in the electric power company (utility) between Rp. 707,708,194, - up to Rp. 2581344385, - per year. <br />
<br />
<br />
Potential losses in the electric power company (utility) can be solved with the penalties harmonisa rates apply to customers-customers who menginjeksikan harmonisa flow system to the amount of Rp. 8.38 per kWh (for THDi = 12%) up to Rp. 1460.90 per kWh (for THDi = 50%).<p>Implementation of tariff penalties goal harmonisa is this: to press harmonisa flow distortion (THDi) to the system, reducing the company's potential loss of electricity (utilities) and can force customers to improve the quality of the equipment they use. <br />
