Multichannel intelligent electronic device with advanced communication capabilities

摘要

An intelligent electronic device (IED) for monitoring/measuring parameters of electrical services to a plurality of loads and receiving/transmitting information over communication networks is disclosed. The electrical services may be connected to the same or different AC services. The IED may be configured as a terminal or a server of an Intranet, LAN, WAN, or the Internet. In one application, these techniques are implemented in IEDs such as digital electrical power and energy meters.
