TECHNICAL NOTE

Power Quality: ION® Meters and EN50160

EN50160 is a European standard that defines the voltage characteristics of the electricity supplied by public distribution systems. It provides the limits within which any customer can expect voltage characteristics to remain. Some ION meters have a default configuration that measures the supply voltage and presents EN50160 statistics according to a set of guidelines defined by Eurelectric (UNIPEDE).

(Visit http://unipede.eurelectric.org for a copy of the Measurement Guide for Voltage Characteristics– reference 23002Ren9531.)

These factory configured meters already provide data to aid in EN50160 compliance determinations. The meter’s front panel and the Vista diagrams display a range of EN50160 statistical information by default. Certain ION meters are also provided with many EN50160 parameters for Modbus systems. Refer to the meter’s User’s Guide for more information on these parameters and their Modbus addresses.

This technical note summarizes the EN50160 data and statistics measured by the ION meters that comply with the EN50160 standard. A description of the EN50160 counters and external controls is also provided.
