For an AC motor to perform at its maximum capacity, running current data is important. This study aims to develop a wireless current indicating device for AC motors that will provide running current data for electrical engineers. This data will eventually be analyzed and used to increase the load for higher production in oil and gas refineries. In this research one of the subsystem of the wireless current indicator that is, the current detection circuit, is proposed. The design and development of the current detection circuit is aimed to produce a lab-scale technology and low in cost. In terms of detection, a fundamental current detection device such as current transformer and current sensors are being tested. The proposed design of the circuit will be simulated and the result will be validated with a real value of an AC motor current reading.
