Power transformer protection relaying (overcurrent, restricted earth
Both windings of a transformer can be protected separately with restricted earth fault protection, thereby providing high-speed protection against earth faults for the whole transformer with
IEEE Guide for Protective Relay Applications to Power Transformers
This guide deals primarily with the application of electrical relays and over-current protective devices to detect the fault current that results from an insulation failure.
Transformer Protection Theory
Correct transformer protection setup and configuration is essential to ensuring, not only proper but, optimized transformer operation (in terms of both performance and efficiency).
