Desenvolvimento de protótipo de um circuito eletrônico para localização de aterramentos em sistema de corrente contínua

Abstract

The operational performance of an oil refinery is conditioned on the need to avoid disruption of the units in the plant, thus allowing a good profit, but mainly to an industry that is safe for workers and for society. This way it is necessary, among other factors, that this industry be a power system highly reliable because it is through this that instruments, actuators, consoles, systems security and protection system ensure this safety. This creates the need to build a new device for location of grounding in a direct current system with low cost assembly, able to decrease the time that the system remains current with the defect (grounding), automating troubleshooting, generating gains including maintenance time spent on immediate interventions.
