SVERKER900 - Testing impedance based protection
The impedance measurement schemes are widely used for protection of different assets within electric power systems. Relay protection devices utilizing such schemes are benefiting from continuous monitoring of both voltage and current quantities within the protected circuit and the calculated impedance value is employed to determine whether the circuit is operating in a normal condition or not.

SVERKER900 - Testing negative sequence overcurrent protection
Unbalance phase currents in a power system that exceed the allowable normal operation limit can indicate abnormal condition or even existence of fault(s) in the system. The operating principal unbalance over current protection is normally based on measurement of negative sequence component of unbalance phase currents. Similar to phase over current protection, normally a pick up (start) threshold and a definite time delay for operation can be set.
