Abstract

Community service program is a mandatory activity for higher eduacation in community empowerment and development. These activities include training programs and application of appropriate technology including the utilization of solar energy for water pumps in orphanages in Rokan Hulu regency and the street lighting program in Simpang Petai village, Kampar regency in Riau province. This activity also considers to the obstacles faced by the community with offering and implementing appropriate technology to them as beneficiaries. This activity takes place with the involvement of students in work and lecture program (KKN) that integrated with community service activities.It is shown that the community as beneficiaries have joined diligently and received assistance with this program by implementation of solar water pump and street lighting. The evaluation of this activity shows that collaboration continues between the community and the Department of Electrical Engineering, Faculty of Engineering, University of Riau and the communitis feel helped and there is an improvement in the electricity infrastructure in their village. This activity was carried out in a fostered village by the Faculty of Engineering, University of Riau.

Abstract

This simulation study presents the effect of lightning strikes on the performance of arresters at 150 kV overhead lines. Lightning strikes have several parameters that affect the performance of line arresters (LA), namely lightning charge, and impulse energy. The simulation was attempted by injection of a direct strike to the ground wire with the peak voltage of 10 MV. The peak voltage was varied in terms of wavefront time (Tf) and the duration of lightning impulses (tau). In order to calculate current, charge and impulse energy of LA from various variations of Tf and tau, the trapezoidal numerical integration method is used. The current and impulse energy arising due to direct strikes and various variations of Tf and tau will be compared for each phase so that the influence of Tf and tau can be obtained from the performance of the LA and the current charge and impulse energy values are still within the limits of the IEEE C62.11 standard. The installation of LA and the position of arresters affected the peak voltage of lightning on the phase line when lightning struck it. The line arresters provide a drop in the peak voltage of lightning in phase lines. By installing line arresters in each tower, it will reduce the peak voltage of lightning on the phase line more significantly than the standalone line arrester. It is shown that the line arresters have to install at least six towers to reduce the peak voltage in the phase lines.
