1.4 Field of application of the product
1.4.1 Intended use
The module is designed for use within an Axioline F station.
The power measurement module is used for direct measurement of AC currents up to 5 A,
including neutral conductor current and phase conductor voltages up to 400 V AC (phase
to neutral conductor) or outer conductor voltages up to 690 V AC (phase to phase).
The module is used to perform analysis of AC networks. You can use it in distribution sys-
tems for measuring current, voltage, and power, as well as detecting distortion and harmon-
ics.
You can use the power measurement module in two operating modes.
In "R.m.s. Values" mode, the module acquires mains variables in three-phase mains. The
following are mains variables:
– Phase currents
– Neutral conductor current
– Phase and phase conductor voltages
– Real, reactive, and apparent power
– Power factors of phases
– Power flow directions
– Frequency
In "Instantaneous Values" mode, the module acquires the instantaneous (scanning) values
of a measuring signal. This measuring mode is used to analyze the waveform of the mea-
suring signal.

2 Connection methods
Whatever connection method is used, the currents and voltages can be connected directly
or via transformers/transducers. The following example shows the wiring for a four-wire
three-phase mains with measurement of the neutral conductor current.
Make sure that the potential of a connected neutral conductor is close to ground and does
not exceed 45 V AC to ground.

Connection methods
108138_en_01 PHOENIX CONTACT 9 / 42
2.1 Direct connection
The power measurement module has the advantage that currents can be connected di-
rectly, i.e., live. Direct connection is possible up to a nominal current of 5 A and a phase volt-
age of up to 400 V.
The measuring range is between 0 A and 6 A.
A current of above 5 A is considered over-range.
From firmware version 1.10, the module generates a warning when the current exceeds 5
A with the text “Overrange”.

transformers
Voltages
To ensure electrical safety at voltages higher than 400 VLN/690 VLL (measuring category
CAT II) or 300 VLN/425 VLL (measuring category CAT III), use voltage transformers for the
connection.
Ground the secondary neutral conductor connection of the voltage transformers.
In high-voltage networks, use single-position isolated voltage transformers grounded at the
cold end (connection X instead of V).
Currents
To ensure electrical safety at voltages higher than 400 VLN/690 VLL (measuring category
CAT II) or 300 VLN/425 VLL (measuring category CAT III), use current transformers for the
connection.
Ground the current transformers.

2.4 Cable lengths of the current transformer
One technical characteristic of a current transformer is the maximum load that can be con-
nected on the secondary side. The maximum load is usually specified as the apparent
power (VA). This value indicates to what extent the transformer may be loaded on the sec-
ondary side. This value can mean that the power occurs directly at the cable resistances,
for example. This may then limit the cable lengths or the cable cross section may have to be
increased.
You can calculate the active power that occurs at the cable resistance as follows:
P = I2 ∙ρ∙2l/A
Where:

2.5 Parameterizing the module
You can parameterize the module using application objects 0E10hex to 0E26hex. The ob-
jects are listed in Section “Objects for parameterization” on page 33.
You do not need to parameterize the current and voltage inputs themselves.
2.5.1 Direct connection
Connect the current and voltage inputs directly to the 3-phase mains and the load.
Note that the default value 10dec is parameterized for a transmission ratio of 1:1.0 in the
objects 0E23hex and 0E24hex.
2.5.2 Connection with current transformers
Accuracy of transformers
Current transformers are usually less accurate than the module itself.
In order to correct the ratio error, you can adjust the transmission ratio.
Note that the real value of the transmission ratio is parameterized in object 0E24hex.
The value can be set with a resolution of one decimal place.
Example correction of a ratio error:
Example correction of a ratio error:
Table 2-1 Correction at current transformer
sec.I (mA) Secondary current transformer
900 ... 1100 1 A ±10%
4500 ... 5500 5 A ±10%
Transmission ratio specified for the transformer: 1 : 20.0
Actual primary current: 100 A
Current measured by module: 4.9 A
Secondary nominal current: 5 A
Resulting real transmission ratio: 1 : 20.4
Value to be parameterized in object 0E24: 204dec
When selecting measuring transducers, please note that their phase angle error has a
considerable influence on the accuracy of the active and reactive power, but not on the
current, voltage, and apparent power.
A phase angle error of 1° can distort the active power or fundamental reactive power by
up to 1.7% of the apparent power, but the apparent power is not distorted.
The module cannot correct this error.

14 / 42 PHOENIX CONTACT 108138_en_01
Example:
Over-dimensioned current transformers
When using current transformers that are operated well under their nominal value, the dis-
play of measured values may lose resolution, i.e., the number of significant digits is lower
than necessary for measurement.
2.5.3 Connection with voltage transformers
Once there is no measuring range switchover for the voltage inputs, the secondary voltage
should be as high as possible when selecting the transducers in order to achieve high mea-
suring accuracy.
When it comes to the accuracy and selection of voltage transformers, the same correction
methods apply as for current transformers (see above).
Apparent power 120 kVA
Maximum error with 1° phase angle error 2 kVA
Actual fundamental reactive power 10 kVAr
Measured fundamental reactive power 8 ... 12 kVAr (worst case)

Operating modes
108138_en_01 PHOENIX CONTACT 15 / 42
3 Operating modes
You can use the module in different operating modes:
– RMS values (basic measured values, RMS values for currents and voltages)
– Instantaneous values (scanning measured values)
All values are created at a sampling rate of 8 k sample/s.
3.1 RMS values operating mode
RMS values are used to acquire mains variables.
See object 0E11hex, 00hex: RMS value (RMS).
Figure 3-1 RMS values (not to scale)
The current and voltage signals pass through a low-pass filter (3.2 kHz) to reduce the har-
monic components and a high-pass filter (1.25 Hz) to reduce the DC components.
The transient period for the filters is 59.9 ms for an accuracy of 1% and 88.4 ms for an ac-
curacy of 0.1%.

AXL F PM EF 1F
16 / 42 PHOENIX CONTACT 108138_en_01
3.2 Instantaneous values operating mode
Instantaneous values are used to detect rapid changes in current, voltage peaks or dips,
etc.
See object 0E11hex, 01hex: instantaneous values.
Figure 3-2 Instantaneous value (scanning values) (not to scale)
Scanning measured values are the instantaneous values of current and voltage according
to phase, as well as neutral conductor current.

You can use object 0E15hex to set the measurement interval for energy metering to the
nearest half-wave.
Power measurement
Active and reactive power are displayed with the correct sign according to consumption and
supply output or inductive and capacitive load.
– Active power: sign depending on consumption or supply, additionally via the status bit
E in the object 0E31hex.
– Reactive power: sign depending on inductive or capacitive load, additionally via the sta-
tus bit B in object 0E31hex.
Energy meters
The active and reactive powers are displayed with the correct sign depending on consump-
tion and supply or inductive and capacitive load.
If the energy flow direction changes to consumption or supply, these values are added to
the counter value with the correct sign.
– Active power: sign depending on consumption or supply, current direction of flow via
the status bit E in the object 0E31hex.
– Reactive power: sign depending on inductive or capacitive load, current direction of
flow via the status bit B in object 0E31hex.
– S0 pulses
You can control the energy meters via the object 0E50hex.
From firmware version 1.10, the module stores the energy values retentively.
S0 pulses (object 0E3Ahex)
S0 pulses can be forwarded for energy recording outside the controller. The S0 pulses re-
flect the total active power of all three phases.
You can configure S0 pulse rates between 1 and 1,000 pulses/kWh via object 0E26hex.
After changing the connection method, reset the energy meter.

Harmonics analysis
The RMS values of both the fundamental waves and the harmonics of voltages and currents
are measured once per second up to the 63rd harmonic (50 Hz) or up to the 55th harmonic
(60 Hz).
The total harmonic distortion is then calculated from this.
Measurement of mains frequency (object 0E30hex)
The measured frequency per phase can be read out as a float value.
Measurement of phase angle (object 0E37hex)
The measured phase angles between current and voltage can be read out for each phase
as a float value.
