Abstract

To operate the water pump, an electric motor is needed as the driving force. In order for the energy consumption needed to operate an electric motor to be regulated, it is necessary to manage electrical energy at the pump station. One example of a pump station is the local water company (PDAM) Unit Wendit Malang City. This unit consists of 3 pump stations namely Wendit 1, Wendit 2 and Wendit 3. These three parts are supplied by 2 transformers with a capacity of 1110 kVA for Wendit 2 and 1730 kVA for Wendit 1 and 3.From the results of power factor measurements in the three sections, it is known that the power factor value at the Wendit 3 pump station is 0.82. This value does not meet the PLN minimum standard, which is 0.85. To improve the low power factor, two recommendations were given, namely the installation of VSD (Variable Speed Drive) at the PDAM Unit Wendit 1 and 3 pump stations and the installation of a Capasitor Bank at the PDAM Unit Wendit 2 pump station.Based on the analysis, the power factor value PDAM Wendit 3, which was originally 0.82 increased to 0.9. In addition, there are savings in electricity consumption per month of 10.48% at PDAM Unit Wendit 1 and 3 and 28.32% at PDAM Unit Wendit 2.

Abstract

The transmission system is a system that often experiences lightning strikes and can cause back flashover (BFO) if there is a direct strike on the ground wire or on the tower. Lightning strikes can also cause touch voltage and step voltage hazards when lightning strikes the ground surface. Grounding is a safety device that functions to protect equipment, systems, humans and other living beings from electrical surges, especially lightning strikes. The grounding resistance value on the tower must be made as small as possible so as not to cause high tower voltage which can ultimately disrupt the transmission system. The grounding resistance limit according to PUIL 2000 is no more than or equal to 5 Ohms. This study aims to evaluate how feasible the tower and its protective devices are on the tower, including grounding and arresters in the event of a lightning strike. By collecting data, calculating tower voltage and simulating lightning overvoltage with the ATPdraw application. From testing the tower voltage by taking a sample on a tower with the highest grounding resistance of 5.8 Ohms on tower T63, the tower voltage value was obtained at 169.94 when given a current of 20 kA, 345.6 kV when given a current of 40 kA, and 682.03 kV when given a current of 80 kA. By calculation and simulation that the tower voltage value does not cause Back flashover (BFO) so it can be categorized as safe and feasible from lightning strike interference.

Abstract

In this era, Indonesia's industry is rapidly developing and relies heavily on electrical components, especially in the Agro-Industry Machine Workshop of CV. Karya Brawijaya. CV. Karya Brawijaya is an industry that produces agro-industrial machinery. In the planning of external protection systems, the commonly used methods are conventional lightning rods and electrostatic methods. Therefore, to further examine the situation, observations conducted in the industry revealed the absence of a lightning protection system. Hence, the author aims to plan and compare the two types of lightning protection systems, namely conventional (Franklin) and electrostatic (E.F. Lightning Protection System), in terms of protection, technical aspects, economy, advantages, and disadvantages. The research and observations were conducted in the CV. Karya Brawijaya building area, using data collection techniques such as direct observation, interviews, and literature studies. This process yielded building layout data (height, width, and length) and data on thunderstorm days in 2019 (IKL 243). These data were then used to calculate the parameters for lightning protection system installation planning according to the standards set by SNI 07015-2004 and PUIPP. The results of the conventional method (Franklin) planning, with air terminations using rolling spheres, showed that 9 finials were installed, allowing the building to withstand currents up to 160.06 kA. On the other hand, the electrostatic method (E.F. Lightning Protection System) planning resulted in the installation of 1 finial, enabling the building to withstand currents up to 23.737 kA. If the current exceeds these values, the lightning protection system will capture the lightning strike.
