Line Differential Protection
SPRECON-E-P DL6
The main function of the SPRECON-E-P DL..6-Series is the differential protection of power lines and overhead power lines. The devices include standardised hardware modules and firmware. They all provide protection functions of the same range. The series consists of:
- SPRECON-E-P DL..6-1 (Protection devices with control function)
- SPRECON-E-P DL..6-2 (Modular protection and control devices)
Modular one-box solutions show higher application 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 comprehensive protection, measurement, control and monitoring tasks in secondary systems.
Areas of Application
The SPRECON-E-P DL..6 devices are multifunctional devices for protection, control and automation of energy stations. They serve as line protection of two-end lines that can be fed from one or both sides concerning all neutral-point connections at medium and high voltage levels.
In addition to the three- or optional four-section characteristics of stabilised differential protection for phase currents, SPRECON-E-P DL..6 also comes with characteristics of stabilised earth current differential protection, amplitude and vector group matching, zero-sequence filtering, inrush and overexcitation stabilisation for transformers in the protected zone. The protection functions are completed by additional features that allow realisation of typical protection concepts.
The implementation of standard and proprietary protocols allows close collaboration with controlling systems of various manufacturers.
Operating
In order to meet the requirements of efficient system management, all operations can be accomplished 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 full-graphical display of the control panel. Additionally, configurable LEDs are available for signalling. Separated navigation keys allow clear user guidance through the various pages and submenus. Furthermore, they facilitate simple configuration of extensive protection and control functions.
Range of Functions
The devices are accentuated by a technologically fully developed and commercially optimised design. They allow realisations of sophisticated and compact solutions with clear economical benefits through highest possible flexibility and scalability.

Configuration
All 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 separately configured or deactivated depending on the respective application. Irrelevant functions are hidden and inactive which allows simple and structured configuration of the devices. All configured bays are type-oriented stored in a database. They can be therefore copied and re-used as well as easily re-adapted, which facilitates configuration of largescale systems.
