ABOUT US

Joint Engineering S.r.l. & Project Unit D.o.o. are two companies working in the field of High/Medium Voltage Substation Design.

Both companies have same owners and Management and are acting toghether on market.

Capability and knowledge is very much similar; projects assignement selections depends of various factor like current workload, continuation of similar works...

Both companies use same Inteligent Design tools which guaranty same design principle as, well allows interchange of project.

Typical substations engineering services:

·        Single Line Diagram (with protection and measuring)

·        Block Logic Diagrams (determine the operation logic of each apparatus/relay)

 ·        Overall Schematic Diagrams (per bay) with interconnection between various S/S equipment (GIS LCC-Protection-Control-AC/DC supply…)

 ·        Protection/Control Schematic Diagrams – as alternative to above Overall Schematics

 ·        Protection Setting Study

 ·        Synchronising and Voltage selection Schematic Diagrams

 ·         OLTC panel Schematic Diagrams

 ·        Metering panel Schematic Diagrams

 ·        Busbar protection Schematic Diagrams

 ·        Breaker failure protection Schematic Diagrams

 ·        Generator Protection Schematic Diagrams

 ·        GIS Local Control Panel Schematic Diagrams

 ·        MV/LV Cubicle Schematic Diagrams

 ·        Cable list / Cable interconnection

 ·        CT and VT Calculation (with regard on connected equipment)

-         Panel Front and Internal arrangement
-         Panel Wiring Diagrams

Design Tools and Design output

We works with Inteligent Design software, a tool which permit us to make automatic interconection between potentials and equipment from various sheets and drawing. Apart significant time saving in design process, as well polarity and wiring check, this tool output number of reports useful for panel construction, and site works. Some of this reports are:

-Bill of Material

-Internal panel Wiring list,

-Terminal Diagram,

-Ferule list by type,

-Cable schedule,

-Cable label and ferule list

-Cable routing.

​

Internal panel Wiring is done taking into account optimal wiring path, wire section...

Supply supervision is connected on the end of wiring chain.
