Michael Kurniawan 2018123456 University of Cincinnati Midterm Exam Power Distribution & Transmission 1. The stages and calculations for determining the support between 2 towers are a. Determine the mechanical characteristics of the conductor wire b. Performing andongan calculations for the same height tower  Finding the maximum stretch of the conductor wire Explanation :  Find the weight of the conductor expand the cross section Explanation :  Finding the conductor wire work Explanation  Find the conductor pulling force (k) using q1 Explanation :  Find the conductor pulling force (k) using q2 Explanation : 2. OHIO region 500kv transmission line map 3. The corona phenomenon in electric power transmission occurs because the air around the conductor is ionized and there is a release of charge that causes insulation failure in the air. Initially there is a neutral atomic molecule medium in a strong electric field region ionized by plants that create positive ions and free electrons, then the electric field operates and separates the charged particles, prevents, and recombines. Due to the increase in energy, it undergoes the same separation process and creates an avalanche of electrons. Power losses due to the corona phenomenon can be formulated: Parameters: Explanation : 4. Types of Substations a. Based on equipment installation  Outside Plug Substation  Inner Plug Substation  Combination Substation b. Based on voltage magnitude  Extra High Substation  High Voltage Substation c. Based on busbar  Ring busbar system substation  Single busbar substation  Double busbar substation  One and a half busbar substation
