Power Transformer Protection Relaying Overcurrent Restricted Earth Fault Differential Eep from electrical-engineering-portal.com

By some a form of overload protection, but the pickup of such relaying equipment is usually too high to provide effective transformer protection except for prolonged short circuits. The importance of effective transformer and control transformer protection cannot be over emphasized. Figure 5(a) presents a power transformer magnetizing characteristic.

In addition to the above, mechanical relays such as buchholtz relays and sudden pressure relays are widely applied to transformer protection, and are particular to application to transformer protection. Setting procedures are only discussed in a general nature in the material to follow. Power transformer protection | www.pdhlibrary.com protection must stay stable during the inrush transient. After motors, transformers are typically the second most common application where proper overcurrent protection is required and utilized to provide the necessary protection to facilities, electrical systems, equipment, and most importantly

Overcurrent protection • possible primary protection for small transformers • backup of primary protection (87 and 63) • backup protection for faults in adjacent protection zones (trip transformer before it is damaged) transformer damage curves • infrequent fault incident curve (fewer than 5 faults in life of transformer)
