Prediction of Ignition Possibility of Self‐Regulating Heating Cable Using Current Signature Analysis

Fire and Materials, Volume 50, Issue 1, Page 94-107, January/February 2026.
ABSTRACT A self‐regulating heating cable (SRHC), which has the advantages of ease of use and economic feasibility, is widely used in various industrial processes to prevent the freezing of pipes and maintain temperature. However, if the SRHC, a heating element, loses its temperature control ability due to internal and external factors, it may ignite ...
