Item Análise comparativa entre as leituras de valores RMS de diferentes medidores, diante de sinais senoidais e distorcidos(Universidade Federal de Goiás, 2019-07-09) Cunha, Luiza Ferreira da; Belchior, Fernando Nunes; Belchior, Fernando Nunes; Oliveira, Antônio Melo de; Nerys, José Wilson LimaIn order to meet the need for equipment that emulates different load conditions in electric motors, the system described in this article was designed in conjunction with Prof. Dr. Geyverson Teixeira, to be incorporated into the laboratories of the Federal University of Goiás. Using a simplified architecture in the design, the construction, use and maintenance of the system can be done quicklywith components easily found in the market. The premise of the equipment is to drain an electric current with known value from an electric generator, so that by varying the value of this current, a load can be emulated on the generator shaft. The power value is controlled from a Pulse Width Modulation (PWM) generator, where the pulse duration determines an average current value. The power generated will be dissipated into a specific resistor, designed for high power dissipation, coupled to a temperature monitoring sensor and cooling system, to prevent overheating and damage. Information about the system will be displayed on an LCD display for operation.Item Carga resistiva regulável para geradores CC e CA(Universidade Federal de Goiás, 2019-07-07) Pureza, Lucas Hernandez; Souza, Sávio Gabriel; Paula, Geyverson Teixeira de; Paula, Geyverson Teixeira de; Melo, Fernando Ferreira de; Brigatto, Gelson Antônio AndrêaIn order to meet the need for equipment that emulates different load conditions in electric motors, the system described in this article was designed in conjunction with Prof. Dr. Geyverson Teixeira, to be incorporated into the laboratories of the Federal University of Goiás.
