Application
The digital Weigel Power Meters have been designed to display the
electrical parameters in low voltage systems. The meters are suitable for
use in 3 - phase 3 - wire or 3 - phase 4 - wire systems 230/400 V and for
use with current transformers N/5 A.
WPM 735 E-H-T-AO-V3 is equipped with harmonics analysis, SOE
(event monitoring) as well as 8 status inputs, 2 pulse outputs and
1 analog output
WPM 735 P-H-V3 is equipped with harmonics analysis and Profibus
The panel meters display the electrical parameters in the network: 
voltages phase to neutral and phase to phase, currents of the 3 phases,
neutral current; unbalance rates for currents and voltages; active power,
reactive power, apparent power and power factor of the 3 phases and in
total; frequency; active energy and reactive energy in 4 quadrants (im-
ported/exported, inductive/capacitive); demand and maximum demand
of the currents and powers; harmonics of current and voltage up to the
31
st
 harmonics as well as total harmonic distortion (THD).  Various rat-
ings are displayed at the same time and can be selected by pressing
buttons.
Special events SOE (Status of Events) are recorded with date and time
stamp.
Using the integrated RS485 or Profibus interface, all measured ratings
and the events can be read out and settings can be made. 
Software for read out and configuration is available via download from
www.weigel-messgeraete.de
Using the front - side buttons, the voltage and current transformer ratios,
the system type and communication parameters can be set and the en-
ergy counters and demand values can be reset.
Functional Principle
WPM 735 is a microprocessor-controlled digital measuring device for
measuring, calculating, and indicating electrical ratings.
The meter has 3 voltage inputs and 3 current inputs to enable simulta-
neous evaluation of voltage, current and power for all three phases.
The meter must be connected via current transformers.
