Modern grid is the most complex man-made monitoring system, which is a Wide-Area Monitoring System (WAMS). Next-generation smart grid will play a crucial role which will provide time synchronization of the data, the electric power system status (WAMS), protection and control. WAMS will provide safe and efficient energy transfers well as reliable and optimize the management of the grid. Fuses are used more in power supply, transmission lines and associated equipment. As a general rule increased Uses of fuses can be attributed to the low-cost, simple to maintain and reliable protection. Application of fuse is one of the main areas in the entire conservation plan and other significant protection coordination unit used in smart grids.
