Curva de Daño de Equipos

This document shows the protection settings and curves for the relays protecting a substation transformer and motor. It displays the settings for the overcurrent protection relays on the primary and secondary sides of the transformer, including pickup values, time dials, and time delays. It also lists the settings for the motor protection relay, including its pickup value, time dial, and time delay. Graphs show the tripping curves for each relay on the log-log scale.
