Differential Relay: Compares currents at two points; operates when there is a difference (used in transformers and generators). He has a BS in EE from Lehigh University, a MS from New Jersey Institute of Technology, and a MBA from Fairleigh Dickinson University. Rockefeller is a Fellow of IEEE and Past Chairman of IEEE Power Systems Relaying Committee. But when a transformer overheats, faces a sudden fault, or experiences overload-even for a few seconds-the entire system feels the impact. Recognized under 2(f) and 12 (B) of UGC ACT 1956 (Affiliated to JNTUH, Hyderabad, Approved by AICTE - Accredited by NBA & NAAC – 'A' Grade - ISO 9001:2015 Certified) Maisammaguda, Dhulapally (Post Via. Kompally), Secunderabad – 500100, Telangana State, India To introduce all kinds of circuit.
