Abstract
In carrying out the production process, the induction motor will be used continuously so it is prone to interference. The disturbances that often occur in 3- phase induction motors include overcurrent and overload. Several components of the protection system commonly used in induction motors are thermal overload relays. Thermal Overload Relay (TOR) is an electronic device to secure overloads based on temperature (Thermal) which has a relay to disconnect a control circuit such as direct online and start. delta. Meanwhile, the Electronic over current relay (EOCR) is an electrical component that functions to limit the current flowing to the motor. Based on the advantages and disadvantages between TOR and EOCR, the surface aerator motor control panel which previously used TOR was upgraded to EOCR in stages starting from EN8, EN9 and EN2M. with the aim of providing more protection to the motor to minimize damage such as burnt stator coils. The use of EOCR is more effective for protecting a motor control system, because it has more protection features than TOR. EOCR also has a display that displays the current value for each phase so it is easy to find out if there is an imbalance in one of the phases. EOCR also has a fail safe mode which can be used to provide more protection to the motor if the EOCR malfunctions
