Leakage current sensing techniques

Present paper gives overview of leakage current sensing techniques. As it is important to monitor and maintain the leakage current at the lower side by engineers and electric companies, this paper describes the highlighted concepts of leakage current for general electrical devices or instruments. In addition to this, various methods of measuring leakage current are reviewed. It also reports the current sensors in accordance with principle in order to mention their positives and negatives. Whereas some of the current sensing techniques rise with the new principles, for example Hall-effect sensors and fluxgate sensor or advanced technologies such as magneto resistance effect sensing and fiber-optic techniques which provide alternatives in current sensing, almost at affordable price than traditional techniques just like shunt resistors. In addition to this, the system will be modified with transmitter block and receiver block which are connected to leakage current sensor and remote controller respectively. This can be used for data processing and storage of data.
