Feasibility Study of Connecting Device for Low-Voltage on Transformer Mast Substation at PT PLN (Persero) UP3 Padang

Abstract

Abstract- Low-Voltage Connect Device (PHB-TR) are vital components in low-voltage electrical distribution systems that ensure the safe and reliable flow of electricity to various equipment and circuits. Feasibility studies of low-voltage connecting devices are key to ensuring optimal panel performance and safe operation. This study details the results of work in the feasibility test of connecting devices for low voltage covering various stages, such as panel construction, PHB-TR electrical characteristics, PHB-TR components, and Transformer Pole Substation (GTT). The feasibility testing process starts by measuring the load of the G.248 T Padang distribution substation and also considering factors such as determining the NH Fuse current, determining the size and KHA of the busbar, determining the insulation resistance of the cable, and determining the grounding resistance of the GTT according to and the protection required. Final documentation includes test notes, modeling using applications and software, and other important information needed for future maintenance and repairs.  The result of the feasibility study of this low-voltage connecting device is that it is well installed, complies with applicable safety and technical standards, and can support reliable electricity flow to connected equipment. With careful planning, low-voltage connecting devices will serve as critical components in an efficient and reliable low-voltage power distribution system.
