Title
Digital Protection Of Power Transformer
Authors
Abstract
Electric Power utilities traditionally use electromechanical or solid state differential relay to detect winding faults in power transformer. These relays use harmonic component to restrain the relay from operating during non-fault case. Existing electromechanical & static relay use analog filters to obtain trip & restraint signals. But these relays don't have features like self-checking and flexibility. Also, the electromechanical and analog relays are not suitable for implementation in sub station automation and distribution automation schemes, as they lack capability to communicate. In this paper, a laboratory prototype of a numeric relay for protection of power transformer has been developed. The relay implementation use differential protection with second harmonic restraint for magnetizing inrush and fifth harmonic restraint for over-excitation.
