Abstract

Speed setting plays an important role in the direct current motor, because the motor has a direct current coupling characteristic speed profitable compared to other motors. From both of these characteristics can be used as a basis to set the dc shunt motor speed. If a decline in motor speed due to the increase in load current (Ia), the field current (If) is set (reduced) so that the motor speed be maintained at the desired rotation. In the design of the most important stages of this research. In the design phase to understand the properties, characteristics, specifications of components used and the steps that must be considered by using the block diagram of DC motor supply circuit blocks, smart relay circuit blocks, block string of resistors, and a DC motor circuit blocks, each this circuit has the function block and work differently but interrelated. Based on data and analysis can then be seen that the larger the anchor resistance will decrease the speed of the motor to hold the armature and the greater the speed the greater the resistance to hold field.Keyword : Dc motor speed settings using smart relay

Abstract

Power transformer plays a very important role in the electric transmission system to convert the voltage level of the system. An abnormal operation of power transformer can decrease its reliability. The most common cause of abnormal operation in power transformer is oil damage. Markov method is applied using Dissolved Gas Analysis (DGA) test from transformer oil to determine transformer’s insulation resistance and breakdown voltage. Continuous Markov method is applied to determine steady-state and inntantaneous conditions that occur in the transformer’s oil. Furthermore, Markov process the power transformer must satisfy certain requirements such as lack of memory and stationery or homogeny. After all requirements are met, then the value of each transfer rates and transition times are determined for transformer reliability and availability calculations transition matrix by using rate of failure (λ), rate of improvement (μ), the stead-state value of transition matrix. The sum of all incident condition value, failure rate and rate of improvement are considered as transformer reliability. The result of Markov continuous analysis obtained the transformer reliability for total Dissolved Combustible Gases (TDCG) parameter for initial operation is 0.99 and it decreased to 0.60 after 365 days of operation. The transformer reliability decreased to 39% for 365 days of operation. Furthermore, the transformer availability for duriation of 302 days are considered as good condition for all TDCG gas parameter and not good for 61 days.Keywords : Oil Testing Transformer DGA (Dissolved Gas Analysis), Isolation Resistance and Breakdown Voltage, Markov Continuous Method.

Abstract

Households are one sector of the country with 23% energy consumption of total energy in all sectors. In the household there are many electronic devices that consume electricity. This resulted in energy consumption among households to be very wasteful. For that action is required to minimize the consumption of household electrical energy. There are several ways that can be done to overcome this problem, one of which is to conduct a conservation energy audit. This audit is done using LEAP software. The conservation energy audit process is divided into 3 sections, i.e. energy surveys, initial energy audits, and detailed energy audits. The result of conservation energy audits undertaken include loads of 450, 900, 1300 and 2200 KWh. Finally the conclusion of the overall conservation energy audit is shown as follow, there was a 23% decrease in electricity consumption at 450 kWh load, 25% at 900 KWh load, 17% at 1300 KWh load and 20% at 2200 KWh load. from the test result that has been done, the reduction of annual cost is Rp 63,504 at the load of 450 KWh, Rp 110,538 at the load of 900 KWh, Rp 302.259 at 1300 KWh load and Rp 328,773 at the load of 2200 KWh. This proves that conservation energy audits can help reduce excessive energy consumption levelsKeywords: Energy Audits, Electricity Consumption, Household, LEAP
