Title: Indicating current converter saturation for measuring current in distribution network
Inventor: JURISCH ANDREAS DR ING
IPC: H02H1/04
Filed: 1996-08-16
Granted: 1997-08-28
Abstract: The method provides a detection signal (EK1) indicative of saturation in a current convertor. The signal is connected to an electric power supply network to be monitored and outputs a secondary measurement signal (S) corresponding to the current through the network. A first auxiliary measurement signal (H1) is taken from the secondary signal by low-pass filtering tuned to the harmonic current. The auxiliary signal is off-set in relation to a second auxiliary measurement signal (H2) formed from the secondary signal. The saturation detection signal is formed when the quotient of the first and second auxiliary signals exceeds a predetermined threshold. An intermediate measurement signal (Z) is generated from the secondary signal by differentiation.  The first auxiliary signal is formed from the intermediate signal. The first auxiliary signal corresponds to the component of the first surface wave in the intermediate signal. The second auxiliary signal is formed from the intermediate signal by averaging. After a predetermined time delay after the appearance of a short circuit in the supply network, the saturation signal is formed when the quotient of the auxiliary signals exceeds the given threshold.
