Despite the project's complexity, design time was cut in half.

SATRIA TECHNOLOGIES, A small start-up
company in Selangor, Malaysia, provides engineering
solutions for power utilities, industries, and infrastructure. The country's largest electricity utility,
Tenaga Nasional Berhad (TNB), Kuala Lampur,
(tnb.com/my), contracted with SATRIA to design and
supply control-relay panels for its new substation in
Pandamaran, Klang, a vibrant city where residential,
commercial, and industrial-infrastructure projects are
booming. The contract required SATRIA to design six
different protection and control schemes for nineteen
33-kV/11-kV units to fit in a compact space within
the substation.
In prior TNB projects, SATRIA engineers had a
month to deliver conceptual drawings and schematic
designs. For this engagement, however, TNB mandated that SATRIA complete initial and detailed electrical design and panel-arrangement drawings within a
20-day time frame. "We keep our promises to always
deliver on time. It is one of our core factors," stated
Gottfried Zeller, director at SATRIA Technologies.
Meeting TNB's demand on this fast-tracked project
called for another "Promis.e"-collaborative, intelligent-modeling technology from Bentley Systems,
Exton, PA (bentley.com).

BACKGROUND
As a means of standardizing its electrical-design
project, SATRIA moved from using AutoCAD to
Bentley Systems' Promis.e. To do this, a team of
engineers spent three months transferring data and libraries of information into Promis.e to build a central
database with intelligent properties. The group created the catalog, title block, symbols, standard parts
library, and report templates that could be tailored
to the specific needs of individual clients and used to
support all electrical-engineering projects.
With the central database complete and stored on

SATRIA's server, the company arranged a network
configuration so that all
engineers and draftsmen
could have simultaneous
access to a particular project or
library in the system. This facilitated collaboration and ensured
consistency across all designs and
drawings. The flexibility of Promis.e
allowed the project team to easily configure the information in the database and
efficiently design the different types of control-relay
panels according to TNB's specifications.

ENGINEERING EFFICIENCIES
With intelligent automated functions in place within
Promis.e, SATRIA now had a reliable, organized
design process to accelerate information sharing and
project delivery times while minimizing the risk of
errors.
"When we used AutoCAD," Zeller explained, "we
had hundreds of pages of designs that had to be printed and all the cross references checked manually by
engineers who would then go back to the workstation
to make the corrections in the system. Maybe they
corrected 80%."
Promis.e allows SATRIA engineers to develop an
intelligent model that links, cross-references, and
checks for errors on all project drawings and documents. Using the parts database to build the model,
engineers pick and place the required symbols and
assign the specific device details by selection. The
software then automatically generates bills of materials (BOMs) and reports that otherwise would be done
manually.
Finally, the ability to export designs and drawings
to multiple file formats simplifies communication

Bentley Systems' Promis.e
helped small start-up
company SATRIA Technologies design, and
ultimately deliver, a
complicated, fast-tracked
order of 19 control-relay panels on time for a
Tenaga Nasional Berhard
substation in Pandamaran,
Klang, Malaysia.
