Simplicity in transformer protection
Electrical Engineering, 1947WHENEVER a fault in a transformer is beginning to form, heat is produced locally, which begins to decompose solid or liquid insulating material and, consequently, to produce inflammable gas. This fact has led to the development of gas-actuated relays for transformer fault protection. Such relays have been in use abroad for many years, and more recently

Protection of Power Transformers By Using Continuous Wavelet Transform
MELECON 2006 - 2006 IEEE Mediterranean Electrotechnical Conference, 2006This paper presents the development of wavelet based transformer protection algorithm. Continuous wavelet transform (CWT) is used for analyzing discontinuities in the primary current signal during internal faults. A custom-built transformer with different tap windings is used for the laboratory studies.
