protection function. The devices include stand-
ardised hardware modules and firmware. They all
provide protection functions of the same range
and are available as:
Modular one-box solutions show higher appli-
cation flexibility than protection devices with
control function. Protection devices with control
function have a fixed range of in- and outputs.
Beside protection and measured value collection,
they also feature control of up to four switching
devices. Due to its modular design, the one-box
solution can be easily expanded for realising com-
prehensive protection, measurement, control and
monitoring tasks in secondary systems.
The multifunctional SPRECON-E-P devices feature
a clear separation of control and protection func-
• Separated passwords
• No testing of protection function at feeder nor primary circuit disconnection required on updating control parameters or firmware
RANGE OF FUNCTIONS The devices are accentuated by a technologically
fully developed and commercially optimised de-
sign. They allow realisations of sophisticated and
compact solutions with clear economical benefits
through highest possible flexibility and scalability.
APPLICATION Due to the wide range of implemented protec-
tion and control functions, the SPRECON-E-P de-
vices can be used for various protection and con-
trol applications. They can therefore be applied
to all switchbay types, independent of customer-
specific requirements.
selective protection of one-end and two-end fed
lines (underground and overhead lines), trans-
formers and motors, concerning all neutral point
connections. Motor protection completes the
scaled functions:
• Bay controller with backup protection (HV)
• Industrial switchgear
tions from influencing each other in the devices,
through which independence of the various tasks
is achieved.
Configuraon of control
separating protection configuration from control
configuration, all different kinds of requirements
of different applications can be met.
The protection-specific functions are separate-
ly configured or deactivated depending on the
respective application. Irrelevant functions are
hidden and inactive which allows simple and
structured configuration of the devices.
In the control application all configured bays are
type-oriented stored in a database. They can be
therefore copied and reused as well as easily
readapted, which facilitates configuration of large
scale systems.
system management, all operations can be ac-
complished with the detachable HMI control
panel. Hence, protection configurations can be
locally carried out beside usage of the operating
program “COMM-3“.
devices is shown on the fully graphical display of
the control panel. Additionally, configurable LEDs
are available for signalling.
Furthermore, they facilitate simple configuration
of extensive protection and control functions.
