Overcurrent protection of electrical systems in Oil & Gas industry is a priority for the security of the system; electrical failures involve great economic losses. The electrical protections are configured according to studies performed under the premise of a radial system. Problems in setting and coordination of those protections arise, when various(More)
Induction motors controlled by Variable Speed Drives (VSDs) became a widespread practice in industrial processes. This paper presents a Transient Overvoltage problem analysis related to the interaction between power inverter, motor and cables. Based on a mathematical description of the phenomenon, a computational model was established to analyze this(More)
