SPREBOX Transformator

Mains and power transformers act as key components for power transmission and distribution. Beside highest availability demands, more and more importance is attached to cost-effectiveness, sustainability and environmental compatibility.

New criteria such as power dissipation, revision cycles, switching cycles and many more have to be considered starting at the time of acquisition until disposal.

During a transformer lifecycle several significant tasks arise which are vital to optimal operation:

  • Control and monitoring of mains voltage and/or reactive power

  • Consideration of additional local information for control and monitoring (i.e. smart grids: decentralised suppliers, line compensation etc.)

  • Consideration of additional local information for control and monitoring logics (i.e. active power directiondependent control, dynamic load-dependent adaption of the tolerance range, number of regulation cycles within certain time periods etc.)

  • Guarantee of grid stability (i.e. recognition of continual voltage decrease / reactive power increase)

  • Transformer protection with main and backup functionalities

  • Transformer monitoring (basic information, applicationspecific monitoring functions)

  • Collection and processing of additional operating alarms and warnings (i.e. for event list), which are not directly produced by the transformer, but relevant to its operation

  • Standardised communication and networking of and between all devices within the system plus connection to superior station control or SCADA systems based on standard protocols

  • Remote maintenance in consideration of system integrity, user access control and IT security
    ​​​​​​​

These requirements can be met with innovative system solutions and carefully selected devices for automation and protection. With SPREBOX Transformer, Sprecher Automation provides a turnkey automation solution for transformers based on its approved SPRECON-E platform.

Through its modular design and its standardised interface (terminal strip) to the primary systems – the transformer, the transducers and the switching devices – the user faces a clearly structured and factory-tested turnkey solution for transformer automation including protection technology.

The flexible SPREBOX Transformer solution can be easily customised in order to meet particular user specifications by providing a wide range of functional extension capabilities as well as various connection possibilities to systems of other manufacturers.

SPREBOX solutions are distinguished by a high standardisation level which therefore significantly shortens realisation and commissioning times. As a result, SPREBOX solutions not only feature high availability, but also aim at criteria of growing importance such as cost-effectiveness and sustainability.
