Application

The multifunctional SENTRON PAC5100/5200 devices record and process measurands and events according
to IEC 61000-4-30 Power Quality (PQ) standard. The devices are used on all voltage levels of power-supply
systems. SENTRON PAC5100/5200 devices are used in 1-phase systems, 3-phase systems, and 4-phase
systems (with neutral conductor).

In addition to the measuring function, SENTRON PAC5200 features various recorders (e.g. Measurement
recorder) to record the measurands in programmable time intervals. Long-term data and events are analyzed
and output as report according to power quality standards, for example, EN 50160. The device features a 2­GB memory for data storage.

The input circuits for voltage measurement are galvanically isolated and can be used in IT, TT, and, TN
networks. To ensure galvanic separation for current measurements, the lines connected to the current
measuring inputs are galvanically separated from the current transformers.

The measurements are obtained from the alternating quantities of current and voltage supplied to the AC
inputs. When no external voltage and current transformers are used, the device can process rated input
alternating voltages of up to V
and rated input alternating currents up to 5 A.

The integrated web server can be used to set the parameters and display the measured values on HTML pages
from the connected PC or notebook. The softkeys located on the front of devices with an optional display
enable a limited parameterization and measured value output on the display.

Measurands

An Ethernet interface is available for communicating with the control center and other process automation sys­tems.

The following measurands can be recorded or calculated from the measured quantities:

• Alternating voltage and alternating current

• Unbalanced of alternating voltage and alternating current

• Active, reactive, and apparent power

• Active, reactive, and apparent energy

• Power frequency

• Phase angle

• Power factor and active power factor

• THDS (Subgroup Total Harmonic Distortion) of alternating voltage and alternating current

• Harmonics of alternating voltage and alternating current

• Flicker acc. to IEC 61000-4-15 (only SENTRON PAC5200)

The uncertainty of operational measurements of the measurands is defined as per IEC 62586-1 product
standard, class S (leading standard), the IEC 61000-4-30 power quality standard, and the IEC 61557-12
standard.

For detailed information on measurands and measurements, see Chapter 4.2 and the technical data in
Chapter 13.

Functionality of the Recorders in SENTRON PAC5200

The recorders are capable of recording both measurands and events in parameterizable time intervals. The
following recorder types are used in SENTRON PAC5200:

• Measurement recorder: recording of PQ measurands (acc. to IEC 61000-4-30) and non-PQ measurands
over parameterized periods, for example, 10-second frequency, aggregation of voltage, current, power
etc.

• Trend recorder: long-term recording and monitoring of the voltage change history over a parameterized
period of time in programmable tolerance ranges; 1/2 RMS values

• Fault recorder: Recording of sampled values of voltage and current using programmable triggers.

• Event recorder: recording of voltage events, frequency events, and voltage unbalance events

The device features a 2-GB memory for storing the recorder data.

Communication

To communicate with the systems control and other process automation equipment, the device features an
Ethernet interface.

Ethernet supports the device parameterization, the transmission of measured data, counter values and
indications/events, and the time synchronization via NTP. The communication protocols are HTTP and
Modbus TCP.

Time Synchronization

During operation SENTRON PAC5100/5200 needs the date and time for all time-relevant processes. This
ensures that a common time basis exists when communicating with peripheral devices and enables time
stamping of the process data. The following types of time synchronization can be executed:

• External time synchronization via Ethernet NTP (preferred)

• External time synchronization via fieldbus using the Modbus TCP communication protocol

• Internal time synchronization via RTC (if external time synchronization is not available)

Parameterization

Parameters are set using an internal Web browser with HTML pages from the connected PC or notebook.
Internet Explorer 6 (or higher) is required for this purpose. Devices featuring a display offer a limited
parameterization function using the front softkeys.

4.1.1 Functioning of the Measuring System according to IEC 61000-4-30

SENTRON PAC5100/5200 devices measure the power quality according to IEC 61000-4-30 in 1-phase or
multi-phase distribution systems. The measuring system is implemented according to class A. In terms of
functional scope, measuring ranges, and accuracy, the SENTRON PAC5100/5200 devices are class S.

The basic measuring interval for determining the values for mains voltage, harmonics of mains voltage, and
mains voltage unbalance is a 10-period time interval for 50-Hz distribution systems or a 12-period time interval
for 60-Hz distribution systems. The measurement of the 10-/12-period time intervals is resynchronized at each
RTC 10-minute limit.

Subsequently, the values for the 10-/12-period time intervals are aggregated over additional time intervals (for
example, 10-minute interval at SENTRON PAC5200).

10-Minute Interval (SENTRON PAC5200)

The value aggregated in a 10-minute interval is tagged with the absolute time (for example 01:10:00). The time
at the end of the aggregation interval is indicated as the time qualifier. The values for the 10-minute time interval
are calculated without interruption from the 10-/12-period time intervals.

• Each 10-minute interval begins at an RTC 10-minute limit. At this 10-minute limit, the 10-/12-period time
intervals are aggregated over a 10-minute interval. The last 10-/12-period time interval in a 10-minute
aggregation interval overlaps in time at an RTC 10-minute limit. Each overlapping 10-/12-period time
interval (for the overlapping area, see Figure 4-1) is included in the aggregation interval of the preceding
10-minute interval.

• The aggregation interval enables the power system quality to be evaluated according to EN 50160. The
aggregation interval can be adjusted to other applications using a parameter. A shorter aggregation
interval increases the storage capacity required for measured values and reduces the maximum possible
recording time in the memory.

Flagging Concept

During conditions of undervoltage, overvoltage, or voltage interruption, the measurement method can return
implausible values for other measurands (for example, frequency measurement, voltage harmonics). The
flagging concept therefore prevents an individual event from being accounted for multiple times in different
measurands (for example, a single undervoltage event both as undervoltage and simultaneously as a
frequency change).

Flaggings are only triggered by undervoltage, overvoltage, and voltage interruptions. Undervoltage and
overvoltage detection is based on a threshold value selected by the user. This value determines whether data
are flagged.

The flagging concept is used when measuring the power frequency, mains voltage, mains voltage unbalance,
and harmonics of the mains voltage.

If a value was flagged within a given time interval, the aggregated value containing that value will be flagged,
too. Flagged values are stored and optionally integrated in the calculation or hidden.

time intervals are measured without interruption and overlapping (the overlapping area excluded, see
Figure 4-1).
