Accumulator represents a accumulated (counted) Measurement, e.g. an energy value.- The association to Terminal may not be required depending on how the Measurement is being used. See section Use of Measurement Class for details. - The MeasurementType class is used to define the quantity being measured (Voltage, ThreePhaseActivePower, etc.) by a Measurement. A Measurement must be associated with one and only one measurementType. The valid values for MeasurementType.name are defined in Normative String Tables.
