EN50160 Compliance Limits, continued
Compliance
limits
(continued)
The table below indicates the limit numbers or range of values required for each
parameter to pass Voltage (QOS) compliance and satisfy EN50160 standard.
Harmonic
compliance limit
values
The general approach of EN50160 is to express all voltage characteristics by reference
to the nominal voltage or declared voltage, as appropriate. The table below indicates
the Harmonic Compliance Limit values in relation to the nominal voltage.
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
Harmonic voltage
(Under normal operating
conditions)
10 minute mean rms values
Individual Harmonic voltage up to the 25th shall
be <
the value of Un given under Harmonic
Compliance Limits (see table below) during 95%
of one week
•<
8% THD (THD up to the 40th) < 8
Interharmonic voltage Individual Interharmonic voltage up to the 24th-
25th shall be < the value of Un given under
Interharmonic Compliance Limits (see table on
page 7-28) during 95% of one week
