Compliance
limits
The table below indicates the limit numbers or range of values required for each
parameter to pass QOS compliance and satisfy EN50160 standard, as the default limits.
Continued on next page
Parameter Limits for QOS Compliance to Pass
Un = Low Voltage (LV) Supply nominal voltage, upper limit 1kV
Uc = Medium Voltage (MV) Supply Characteristics - declared voltage, range 1kV to 35kV

±1% during 95% of one week
•
±4% during 100% of one week
Power frequency with no
synchronous connection to an
interconnected system
Mean value over 10 seconds
•
±2% during 95% of one week
•
±15% during 100% of one week
Magnitude of the supply voltage

Supply voltage variations (Under
normal operating conditions,
excluding situations arising from
faults or voltage interruptions)
