| 20100010761 | METHOD AND DEVICE FOR MONITORING A SYSTEM - The present invention relates to a method and a device for monitoring a system such as a cable. Pulses propagating in different directions are distinguished by measuring and sampling current and voltage at a location of the system, frequency transforming the obtained signals, and by extracting signals corresponding to pulses propagating in different directions as linear combinations of the frequency-transformed signals. Such a method is applicable, e.g. when monitoring occurrences of partial discharge on a 10 kV cable. | 01-14-2010 |
