Title:
ENERGY METER WITH POWER QUALITY MONITORING AND DIAGNOSTIC SYSTEMS
Document Type and Number:
WIPO Patent Application WO1998018013
Kind Code:
A3
Abstract:
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 is disclosed. An electronic energy meter that permits the addition of new measurements or testing capabilities without requiring factory modifications to effect such functionality changes is also disclosed. The meter includes firmware which measures the characteristics of electrical energy supplied to the meter and which generates characteristic signals reflective of the measured characteirstics 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. 00000
