  • Characteristics of Transformer Faults in Relay Protection

    Characteristics of Transformer Faults in Relay Protection

    Table I lists failures for six categories of faults (IEEE C37. 90, “Guide for Protective Relay Applications to Power Transformers, Ref. Winding and tap changers account for 70% of failures. Loose connections are included as the initiating event, as well as. Since transformers are among the most expensive and critical components in power systems, proper protection is essential to prevent costly damage and ensure reliable operation. Transformer failure can have severe consequences: Transformer. Fuses are commonly used to provide fault detection for transformers with minimum nameplate ratings up to 5000 kVA, three-phase (Categories I and II). Transformers of 10 000 kVA and larger, three-phase, minimum nameplates (Categories III and IV) are generally protected by a combination of protective. provide protection is the fault that initially involves one turn. A turn-to-turn fault will resu contains substantial harmonics, particularly the second harmonic. While there is some validity to this approach, there are many other issues to be considered.
