PT Perusahaan Listrik Negara (Persero) or commonly abbreviated as PLN is an Indonesian state-owned company operating in the electricity sector, which has one mission, one of which is running the electricity business and other related fields, focusing on customer satisfaction, company members and shareholders. share. To make this happen, PT. PLN uses a tool called a kWhmeter to calculate the number of electrical ener-gy transactions that have been used by customers. Before a kWhmeter is installed on a customer's plot, the kWhmeter must first be tested meter error. If the test meter error reading test is not implemented, then there is a possibility that the kWhmeter will experience interference, causing inaccurate electrical energy measure-ments which can cause losses to the PT. PLN or the customer. The test meter error functions to find out the magnitude of the meter error value for each kWhmeter carried out in the PLN warehouse, if the test meter er-ror results are still within the class range, the kWhmeter is ready to be distributed to PLN customers. By im-plementing the test meter error, you can eliminate kWhmeter abnormalities caused by the product or manufac-turer making the kWhmeter. The test error meter also functions as a physical check for the kWhmeter to have no defects before it is installed on the customer's plot. The test meter error was implemented at PT. PLN (Persero) based on Directors Regulation (Perdir) 088-Z.P/DIR/2016 which is now Directors Regulation (Perdir) 0028.P/DIR/2023.

Primary energy sources such as electrical, oil and gas are energy that is really needed by society and industries. The provision process of these energy sources must adhere to applicable regulations, including the Right of Way (ROW) rules. In the case of the 500 kV Transmission Network Construction from New Aur Duri to Peranap on Sumatra Island, Indonesia, there is a regulatory conflict regarding ROW between the electricity provider (PT. PLN (Persero)) and the oil & gas provider (PT. Pertamina (Persero)), where there is a ROW tangency between transmission tower span overlaps and the free radius of the oil wells. Considering the critical need for both energy sources, the energization of the 500 kV New Aur Duri – Peranap Transmission Line must be carried out with strict of attention to safety in the vicinity of PT. Pertamina’s wells. Therefore, the Faraday Cage method will be used as one of mitigation risks of potential fires due to induced electric and magnetic fields. In this paper, the author explains the risk analysis of the energization implementation for the 500 kV New Aur Duri – Peranap Transmission and Faraday Cage construction design aimed at reducing electric field induction around PT Pertamina’s wells. By implementing this safety measure, the energization of the 500 kV New Aur Duri – Peranap Transmission Line can proceed safely, even in the overlapping ROW area.
