EN50160 Evaluation and Recording
102
Series PM175 Powermeters
Target Values
The EN50160 does not provide target limits for interharmonic
voltages. The ranges of interharmonic voltages selected in the
PM175 are:
Interharmonic THD 2% for 95% of a week
Individual interharmonic voltages shall be less than or
equal to the values given in the following table for 95% of a
week.
Interharmonic
order
Relative
Voltage
2
0.2
3-15
1.0
16-25
0.5
You can change the compliance limit for the interharmonic
THD via the EN50160 PQ Recorder setup. The individual
interharmonic voltage limits can be changed via the EN50160
Harmonics setup.
Mains Signaling Voltage
This characteristic defines the magnitude of the signal
voltages used in some countries for signal transmission over
public supply networks. These may include ripple control
signals in a frequency range from 100 HZ to 3 kHz, and carrier
wave communications signals in a frequency range from 3 kHz
to 148.5 kHz.
The PM175 can evaluate ripple control signaling voltages in a
frequency range from 100 Hz to 3 kHz.
Method of Evaluation
Since evaluating signal voltages is not commonly used, this
feature is normally disabled in your meter. You can enable
evaluation of signaling voltages via the EN50160 Advanced
Setup.
The PM175 evaluates up to four ripple control frequencies.
You can select the required signaling frequencies via the
EN50160 Advanced Setup.
The basic measurement is the magnitude of the signaling
voltage over a period of 3 seconds under normal operating
conditions.
Signaling voltages are not evaluated if the supply voltage
crosses a voltage tolerance limit (15% Un).
Target Values
The voltage levels given by the EN50160 in Figure 1 of Clause
2.13 are taken from the so-called “Meister-curve” which
defines the maximum permissible ripple control voltages in LV
networks.
Compliance with the EN50160 requires that the 3-second
mean of signal voltages shall be less or equal to the specified
limits for 99% of a day.

Basic Device Settings
The following device settings affect the EN50160 evaluation
