Measurement
● Derivation of more than 300 measured variables from the basic measured variables with
maximum and minimum values (slave pointer function).
● At the voltage terminals, SENTRON PAC4200 can be connected direct to 690 V industrial
systems (max. 600 V for Vph, measuring category III, pollution degree 2). Higher voltages
using voltage transformers.
● For current transformers x/1 A and x/5 A. Conversion ratio and current direction
programmable.
● Can be used in 2-, 3- and 4-wire systems. Suitable for TN, TT and IT systems.
● High measuring accuracy: For instance, accuracy class 0.2 in accordance with IEC
61557-12 for the active energy, in other words accuracy equivalent to 0.2% of the
measured value under reference conditions.
Sliding window demand values
● Calculation of the sliding window demand values for
–
Voltages and currents
– Power factor per phase and total system
– Apparent, active, and reactive power per phase as well as total power
● Maximum and minimum values of the sliding window demand with the date and time of
occurrence since startup, the last reset, or the last deletion
● Demand calculation for reactive power VAR

● Configurable averaging time.
Average values over all phases
● Calculation of the average voltage and current values over all phases. The average value
of a three or four-phase system corresponds to the arithmetic mean for the individual
phase values.
● Maximum and minimum average values with date and time.
