evaluation of signaling voltages via the EN50160 Advanced
Setup.
The PowerSmart Socket PQM 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.
