5.4.23 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. 5.4.23 - 121. Operating characteristics of underimpedance protection.

The underexcitation function uses a total of eight (8) separate setting groups which can be selected

from one common source.

The function can operate on instant or time-delayed mode (DT).

The operational logic consists of the following:

• input magnitude selection
• input magnitude processing
• threshold comparator
• block signal check
• time delay characteristics
• output processing.

The inputs for the function are the following:

• operating mode selections
• setting parameters
