3.5 Functional description
The PEM735 power quality analyser is suited for measuring and displaying electrical
quantities of electricity networks. The PEM735 can measure currents, voltages, energy
consumption and power as well as represent individual harmonic components of cur-
rent and voltage for the assessment of voltage and current quality according to EN
50160.
The accuracy of the active energy metering corresponds to class 0.2 S, which is in com-
pliance with the DIN EN 62053-22 (VDE 0418 Part 3-22):2003-11.
The current inputs are connected via external …/1 A or …/5 A measuring current trans-
formers.
The large display of the panel mounting device makes the relevant measured quantities
easily legible and enables fast configuration. In addition, the interfaces (RS-485 and
Ethernet) allow central evaluation and processing of data. Switching operations can be
monitored or initiated via the digital inputs and outputs (Example: switching off uncriti-
cal loads if the peak load threshold value is exceeded).
The PEM735 provides the following functions:
 
Provision of energy consumption data for a well thought-out energy manage-
ment
 
Power quality monitoring for cost reduction and increased plant availability
 
High resolution waveform recording allows analysis of power quality phenomena
