This paper describes an alternate method for performing current measurement for protection of generators and motors, particularly in the oil and gas industry. This technique involves the use of Hall Effect sensors instead of the current transformer (CT) to measure and detect fault current and different wireless communication methods to send and receive the fault signal. The paper first analyzes and asses the risks associated with the use of a conventional CT and come up with test models to further support the use of Hall Effect sensors instead. Three case studies are presented describing the use of Hall Effect sensors as tools for diagnosing the problems with each potential wireless technology. The methods of wireless communication used are analog transmission and digital transmission. For analog transmission, the modulation techniques Amplitude Modulation (AM) and Frequency Modulation (FM) are tested. Comparative studies of cost related to existing and the proposed system have also been done.
