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 2-
GB 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
P-N
= 400 V (347 V for UL condition) and V
P-P
= 690 V (600 V for UL condition)
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.
An Ethernet interface is available for communicating with the control center and other process automation sys-
tems.
Measurands
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.
