Abstract

Evaluation of the electrical installation of a building is something that needs to be done so that the quality of the electrical installation remains in good condition and reliability. This research aims to evaluate the lighting system. Energy needs are currently playing an increasingly important role in human life, one of which is the problem that arises in the use of energy consumption in the New Classroom Building (RKB) at SMK Negeri 1 Kramatwatu. This research aims to determine the value of energy requirements in the RKB building (IKE, kWh , kVA and Cost Tariff), the RKB building is a building that has 2 floors with a total of 12 classrooms, this building was established at the end of 2023, the RKB building has never had an Energy Audit which is useful for identifying inefficient energy use, this energy audit can reduce energy use in order to increase the level of efficiency. To find out the results with data that has been collected using manual calculations and lighting simulations using DIALux software version 12.1. This RKB building uses energy of 17,154kWh/day, 85,770kWh/week, 343,080kWh/month and 4,322,960kWh/year. 226,925VA/Day, 1,134,625VA/Week, 4,538.5VA/Month and 54,462VA/Year. and customer rates Rp. 19,061;/Day, Rp. 95,308;/week, Rp. 381,234;/Month and Rp. 4,574,808;/Year on consumption of lighting power loads and other power loads.

Abstract

The disturbances that often occur in 20kV cubicles are those with low insulation resistance values ​​caused by several factors such as environmental conditions, humidity levels, dust, temperature, water, pressure disturbances and other disturbances. If this disturbance is left unchecked, it can cause short circuits and electric current leaks. Another disturbance that is often experienced by 20kV cubicles is corona, where this disturbance causes a hissing sound in the cubicle and the appearance of rust on the indoor contact parts of the cubicle. If this condition occurs continuously it can cause serious damage to all 20kV cubicle components and cause losses for customers and PT. PLN (Persero). So to anticipate these problems, maintenance is required on 20kV cubicles. PT. PLN (Persero) carries out annual maintenance of 20kV cubicles to increase the insulation resistance value and overcome the problems of hissing and rust caused by corona events. This Industrial Practice assignment discusses the maintenance of 20kV cubicles in accordance with PT's SOP. PLN (Persero). After carrying out maintenance on the 20kV cubicle, the problems that occur can be resolved, such as increasing the insulation resistance value and the disappearance of the hissing sound and rust on the contacts of the 20kV cubicle.
