Reconfigurable circuit monitoring system

A monitoring arrangement, according to claim 9, further including a remotely situated control station for sending the set-up data to the computer circuit.

A monitoring arrangement, according to claim 9, wherein the non-volatile memory circuit includes an EEPROM.

A circuit monitoring system for a distributed power network, wherein power-related waveforms are passed through a multitude of associated network branches and wherein zero-crossings of the waveforms define their respective cycles, the system comprising:

• a plurality of monitoring means, each of which is disposed adjacent an associated one of the branches, for sensing power parameters associated with the power-related waveforms and for generating and transmitting data representative thereof, each of the monitoring means including detection means for sensing the zero-crossings of the waveform and sampling means for sampling the power-related waveform over a plurality of integral cycles for a predetermined number of sample points, and each including a non-volatile memory circuit for retaining set-up data which defines a configuration of the monitoring means so that after a power outage the configuration is not lost;
• and
• a control station, communicatively coupled to each of the monitoring means, for sending monitoring commands and the set-up data to each of the plurality of monitoring means and for receiving and evaluating the data transmitted therefrom.
