EN50160
EN50160 is a statistical analysis of power quality data based on the EN standard. The
statistical package called Quality of Supply (QOS) is built into the PX5, with
monitoring and setup protocols set to determine voltage measurement compliance
required for EN50160 monitoring. The EN50160-required measurement parameters
include Power Frequency, Supply Voltage Variations, Rapid Voltage Changes, Supply
Voltage Unbalance, Harmonic Voltage, Interharmonic Voltage, and Mains Signalling.
The monitoring site is said to be IN COMPLIANCE if the statistical value over one (1)
week for the specified parameters is 95% or greater.
EN50160 Options setup allows users to define up to five mains signalling frequencies
below 3 KHz. Users can also select pre-defined values for main voltage characteristics
of electricity supplied by Low Voltage (LV) and Medium Voltage (MV) public
networks.
NOTE
EN50160 is defined for the electricity supplied at the supply terminals, and does not
deal with the supply system or consumer’s installation or electrical equipment itself.
Since the standard deals with the voltage characteristics which can be expected in
public distribution networks, other aspects essential for supply quality (i.e. short circuit
power) are not treated within the scope of the standard. EN50160 standard is applicable
only under normal operating conditions of the supply system.
