for EN50160
EN50160 is a statistical analysis of power quality data based on the EN (EuroNorm)
standard. The statistical firmware called Quality of Supply (QOS) is built into HDPQ
Xplorer, 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 for some
parameters, 99% for others.
EN50160 setup allows you to define up to five mains signalling frequencies below 3
KHz. You can also select pre-defined values for main voltage characteristics of
electricity supplied by Low Voltage (LV) and Medium Voltage (MV) public networks.
For medium voltage (MV) supply systems, a potential transformer must be used to
provide a step-down ratio to reduce the high voltage of circuits above a 1000 Vrms to a
level for safe measurement. Refer to connecting to a potential transformer on page E-16
for additional information.
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. Different countries use
different limits for compliance, which can be set by the user if needed.
