RELAY PROTECTIONS AND AUTOMATICS

The new digital relay protections and automated systems for MV, HV and UHV devices, demand  design and engineering of new level. All projects have to be made according the specific devices needs and international standards. We prepare the following documents:

• Input/Output Lists for main controllers and relay protections

• Principle diagrams for current, voltage and power circuits

• Principle diagrams for controlling and interlocking the devices

The specialised software that we use for electrical design EL-CAD,  allow us to generate automatically wiring diagrams and cable connections lists. Using this tool we allso can print all wire marks and lables. Other great benefit is that the software is checking all diagrams and drawings for human mistakes.
