ENERGY CONTROL MONITOR SYSTEM PROCONT |
| APPLICATION: |
The Energy Control Monitor System Procont is a
multifunctional device, which should not be missing
in any main distribution. The system is suitable
for panel mounting and detects the load of electrical
distributions and mains. It is conceived for
measurement and storage of almost all electrical
quantities including current and power
mean values.

| 2nd-40th Harmonic |
The 2nd up to the 40th harmonic are calculated from the
scanned values of current and voltage by Fourier’s analysis. They
can be displayed or printed in bar graphics
or curves.
It contains the harmonic contents from the fundamental up to
the 40th harmonic. The bars are given in % of the fundamental.
The curves and bar graphics can be scaled. Within the graphics,
some additional measured values can be read out.

| Maximum Demand Control |
The Energy Control Monitor System Procont is a multifunctional device, which should not be missing in any main distribution. The system is suitable for panel mounting and detects the load of electrical distributions and mains. It is conceived for measurement and storage of almost all electrical quantities including current and power
mean values.
Based on the incoming pulses of the pulse input or total
real power, calculated by the measuring unit, the maximum
demand controller determines the necessary quantities of a
given maximum. The system determines continously the
mean value, actual value, trend value and correction power
within a measuring period.
If the system recognizes a possible exceeding of the maximum,
it checks the necessity of a disconnection with the
reference of the set consumer parameters.
The disconnection is carried out with regards to the consumer
parameters. The target of this method is to keep a set
maximum at the end of the measuring period by as less switchings
as possible to avoid disturbances of operation.
There are 64 Emax channels at your disposal. Those are connected or disconnected according to the following criteria:
|
|
Power values (Target value, mean, actual, trend, correction and
connected power) |
|
Priority and switching mode (normal, cycle, rotation) |
|
Time settings (min./max. disconnection time, min. connection time, make delay, break delay, switching pause) |
| Software |
The program Prorem can be used for programming, reading out and sampling of programmed, measured
and event data.
The following data can be read out or sent,
|
|
Programming (send/retrieve)
|
 |
Configuration data, maximum demand controller, power factor controller, time controller, logic. |
|
Evaluation (retrieve)
|
|
Event memory, peak values Emax, energy, daily graphs, peak values measurement. |
| Time controller |
The time controller of the Energy Control System Procont is equipped
with numerous varieties for the setting. With its 16 channels and
160 free programmable time blocks, it provides the possibility to realize
time programs of daily repeated or one-off intervals in advance of
18 years.
Besides the consumers, also internal functions such as tariff selection,
event registration and request inputs can be operated. The shortest
switching interval is 1 minute. A programmed calendar for public holidays,
vacation days and individual vacation days is integrated.
The available memory for further programmings of the time
controller is indicated permanently.
