Project Summary

Tenaga Nasional Berhad (TNB) retained SATRIA Technologies to design and supply 33-kilovolt/11-kilovolt control relay panels for a new substation in Pandamaran, a constituent of the Klang district in the state of Selangor, Malaysia. The MYR 500,000 project required the team to deliver six different protection control schemes for 19 units to fit in a compact space within the substation. To accommodate the complex design requirements and meet the client’s accelerated 20-day delivery deadline, SATRIA required flexible, intelligent modeling technology.

SATRIA created a central database using Bentley Promis.e to standardize its electrical design process. Engineers transferred data and libraries of information to Promis.e to build a database with intelligent properties and set up a network configuration that enabled concurrent accessibility for the entire project team, which improved collaboration and streamlined workflows. The flexibility of Promis.e allowed the team to configure the information in the database to efficiently design the six different types of control relay panels in accordance with TNB’s specifications.

SATRIA reduced delivery time by 50 percent using Promis.e, supplying design drawings to TNB within the required 20 days, compared to an estimated 40 days for a total cost savings of MYR 20,000. The automated cross-referencing functions in Promis.e reduced resource hours for report generation from days to seconds. Having a collaborative, standardized design process minimized design mistakes and drafting errors, reduced time to prepare bills of material by 20 to 25 percent, and resulted in less waste.

SATRIA relied on Promis.e for an intelligent solution to standardize design procedures, accelerating information sharing and project delivery time. The ability to export designs and drawings in multiple file formats enhanced stakeholder and client communication for more efficient review and revision processes. Using the templates and macros created in the database enabled engineers to produce schematic drawings in one day instead of two. Bentley’s flexible, interoperable technology automated tedious tasks and simplified workflows, reducing errors and enhancing engineering efficiencies to meet client requirements and deadlines.

Project Playbook: MicroStation, Navigator, Promis.e
  • TNB contracted SATRIA to design six different types of 33-kilovolt/11-kilovolt control relay panels for a total of 19 units within 20 days to be installed in the new Pandamaran substation in Klang, Selangor, Malaysia.
  • SATRIA reduced delivery time by 50 percent, saving MYR 20,000 on this MYR 500,000 project using Promis.e.
  • The flexibility and interoperability of Promis.e allowed SATRIA to tailor its intelligent, collaborative, and cost-efficient design process to meet future client and project demands.
  • Upon installation, the control relay panels will protect the primary equipment at the Pandamaran substation and reduce the risk of life-threatening flashovers at the site.
  • “As the project required us to supply six different types of panels with a total of 19 units, a lot of time was spent in the design and drafting works using AutoCAD. To overcome this challenge, the engineering team is now equipped with Promis.e to produce electrical drawings autonomously by developing their own standard libraries and templates that meet TNB requirements.”
