How to monitor the multifunctional electric energy meter

A system for monitoring power quality events of Multifunction Energy Meter storing reference information reflective of different service types to the reference information for the service type to determine the occurrence of power quality events. For each power quality event, at least one of a start time, a stop time, a duration, a measured phase, a magnitude of a measured quantity, and a predisturbance value, and a cumulative total of the power quality events is recorded.



The meter includes firmware which measures the single phase din rail meter  characteristics of electrical energy supplied to the meter and which generates characteristic signals reflective of the measured characteristics of the electrical energy. A processor is connected to receive and process the characteristic signals. The processing of the characteristic signals includes selecting and manipulating certain of the characteristic signals and generating characteristic information in response to the selection and generating additional characteristic information in response to the manipulation.

It is preferred for the meter to include a memory having reference information stored therein. In such an embodiment, the manipulation of characteristic signals includes retrieving certain of the reference information and generating the characteristic information in response to the selected signals and the reference information.Some utilities configure the meters themselves to ensure better control over which meters are installed at which installation sites.

However, such configuration activity adds to the installation cost and does not always reduce the risk that a meter configured for one service might inadvertently be installed at a site supplied by a different service. Therefore, there remains a need for an electronic meter which automatically detects the service type and voltage to which the meter is installed and which either automatically configures its own programming to the detected service or provides a simple means for manual configuration at the installation site.
