5.3.15 Underimpedance protection (Z<; 21U)

Underimpedance protection is an alternative for voltage-restrained overcurrent protection. It can be

used to detect short-circuit faults near the generator even when the short-circuit current is small.

Additionally, under impedance protection can be used as backup protection for transformer protection.

Figure. 5.3.15 - 146. Operating characteristics of underimpedance protection.
