摘要：
Transformers play a vital role in electrical power systems and early detection of faults can prevent its breakdown. Interturn faults account to majority of failures in a transformer. An effective method based on search coils is hence presented in this paper to detect interturn fault. The symmetry of leakage flux pattern can be studied using these induced voltage search coils and its analysis can provide information about any incipient fault. Fault location can also be determined with this method. This paper also includes design calculations for 1kVA, 440/440, Delta-Star distribution transformer under study.
