Patent CA-2297544-A1 (CA)
Inventor: EDEL THOMAS G
IPC: H02P13/12
Filed: 2000-02-01
Abstract: A Current Transformer Demagnetizing Circuit (1) for demagnetizing ordinary current transformers while the current transformers remain in service. Once demagnetized, ordinary current transformers are able to accurately sense non-symmetrical currents, including a-c currents that have d-c components. Devices that incorporate the invention will usually utilize two modes of operation sequentially: 1. a demagnetizing mode, during which the current transformer is demagnetized, and 2. a current-sensing mode, during which current transformer secondary current is sensed. The invention comprises an adjustable impedance (2) with suitable control means (3). The invention is suitable for use with current monitoring systems that derive operating power from the current transformer secondary current, as well as more common applications that do not derive power from the current transformer secondary current.

Abstract: A server and method for determining physical connectivity between end nodes and networking devices within a network. With respect to one embodiment, the method comprises an initial act of establishing levels of priority for a plurality of link types capable of being established between networking devices and end nodes of a communication system. For example, as described herein, the types of links include an inferred link having a first level of priority, and other link types having a lesser priority. Once the priority levels are established, the method involves initially detecting a plurality of links associated with selected ports of the networking devices. After detection of these links, a determination is made from these links as to which links are associated with the end nodes and have the highest priority level. From that group, the physical connectivity between the end nodes and the networking devices is ascertained.
