The discussion centers on the concept of "Differential instantaneous highset overcurrent protection" in relays, specifically in the context of radial feeder protection. Participants clarify that high-set refers to a method of setting relays at progressively higher pickup current values rather than a distinct feature of a relay. The confusion arises from the terminology used in the industry, with some questioning the relevance of high-set protection in differential protection systems for transformers. Ultimately, understanding high-set protection is essential for effective relay configuration.
