INTRODUCTIONThe overcurrent-time protection acts as the main

protection function. The devices include stand-

ardised hardware modules and firmware. They all

provide protection functions of the same range

and are available as:

• SPRECON-E-P DS..6-1 (Protection devices with control function)

• SPRECON-E-P DS..6-2 (Modular protection and control devices)

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-

tions:

• Separated data models

• Separated control and protection firmware

• Separated control and protection configuration

• Separated passwords

• No testing of protection function at feeder nor primary circuit disconnection required on updating control parameters or firmware

RANGE OF FUNCTIONSThe 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.

APPLICATIONDue 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.

The implemented protection functions allow

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

functions.

The devices are especially qualified for the

following application areas due to their large-

scaled functions:

• One-box solutions for utilities (MV)

• Bay controller with backup protection (HV)

• Industrial switchgear

Application of modern technologies prevent func-

tions from influencing each other in the devices,

through which independence of the various tasks

is achieved.

CONFIGURATIONAll functions can be configured separately. By

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.

OPERATINGIn order to meet the requirements of efficient

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“.

All relevant information about processes and

devices is shown on the fully graphical display of

the control panel. Additionally, configurable LEDs

are available for signalling.

Separated navigation keys allow clear user guid-

ance through the various pages and submenus.

Furthermore, they facilitate simple configuration

of extensive protection and control functions.
