Voltage and Power Protection Functions
This section describes the voltage based motor protection functions. The UMC100 together with the volt-
age module VI150/VI155 continuously measures the motor supply voltage (line to line), the motor current
and the phase angle between the current and voltage. The power and energy consumption is calculated
out of these values and used for various protection and monitoring functions. The different process values
can be r
eported to the fieldbus and displayed on the LCD panel.
The following functions are described in this section:
•
Overvoltage, Undervoltage
•
Phase loss
•
Voltage imbalance
•
Total harmonic distortion
•
Overload, Underload
•
Power factor
•
Voltage dip reaction
The following process data are available:

Powerfactor
(cosphi)
The power factor is defined as the ratio of the
real power flowing to the load to the appar-
ent power and is a non dimensional number
between 0 and 1 (also expressed as a percent-
age). The cos phi only considers the funda-
mental frequency.
In this manual both terms are used and
refer to the fundamental frequency only!

Active power
Active power is the capacity of the motor for
performing work in a particular time
0…65535 [1W, 10W, 100W,
1kW] The actual unit depends
on the selected scaling factor.
Apparent power
The apparent power is the vector sum of real
and reactive power.
0…65535 [1VA, 10VA, 100VA,
1kVA] The actual unit depends
on the selected scaling factor.
Voltage Imbalance
An imbalance between the supply voltages in
the network.
0…100%
Total harmonic
distortion (THD)
Harmonic distortion of the mains.

Energy

In section
2 -> Connecting the VI15x Voltage Module
you will find information on how to
mount and connect the voltage module.
All process values generated from the voltage module can be used in the Custom Applica-
tion Editor. Consult the editor's manual for more information.
The digital output of the voltage module 1DO0 can be freely used in the function block edi-
tor. By default it is connected to the command telegram and can be controlled from a PLC.
Before using the voltage module set the following parameters:
•
Nominal line to line voltage
•
Nominal power factor
(cos phi)
•
VI15x enabled
. If the module is enabled the UMC monitors the presence of the module
and creates by default a fault in the event that the module is missing (-> parameter 'Miss-
ing Module Reaction').
