This paper is wrapped around the heating wire, such as water and sewage pipes in plumbing and fire protection water pipes and winter apartments and buildings for frost protection system to prevent freezing. Characteristics of the frost protection system is a system that generates heat by supplying current to the heating wire wound around the pipe. In this paper, we will effectively control the current supplied to the heating coil and to design a system.
