HAL Raktokorobi

HAL Raktokorobi — 1250 kVA Commercial Electrical Substation | POWERtrac

Precision-Engineered Power for a Facility That Cannot Afford to Stop.

Not every great substation project is measured in megavolt-amperes. Some of the most impactful electrical infrastructure work lies in delivering a perfectly matched, expertly executed solution — one where every component is correctly sized, properly protected, and tuned for long-term efficiency. That is exactly what POWERtrac delivered for HAL Raktokorobi in Dhaka: a clean, capable, and comprehensively commissioned commercial substation engineered to keep the facility running reliably, day after day.

The Commercial Power Requirement

Modern commercial and institutional facilities in Dhaka face a consistent set of electrical challenges — varying load profiles throughout the day, reactive power penalties from inductive equipment, and the ever-present need for a power supply that simply never lets operations down. For a facility like HAL Raktokorobi, where operational continuity is non-negotiable, the substation must do more than just connect the building to the grid. It must protect it, optimize it, and sustain it.

What POWERtrac Delivered

1250 kVA, 11/0.415 kV Transformer: A right-sized 1250 kVA step-down transformer precisely matched to HAL Raktokorobi's actual load requirements converts 11 kV grid supply into a stable 415V utilization voltage for the entire facility. Proper sizing — neither under-capacity nor wastefully oversized — ensures optimal transformer efficiency, longer equipment life, and dependable power delivery across all operational hours.

11 kV HT Switchgear (VCB): Vacuum Circuit Breaker-based high-tension switchgear at the 11 kV primary entry provides reliable fault interruption, controlled isolation, and safe maintenance access — placing a robust protective barrier between the grid and every load within the facility. In the event of any fault, the VCB responds instantly, protecting both equipment and personnel.

LT Switchgear — 2000A: A 2000A low-tension switchgear panel manages the internal distribution of power across all areas of the facility — segregating circuits by function, enabling selective tripping in fault conditions, and providing a structured, organized distribution architecture that simplifies both day-to-day operations and future modifications.

Automatic PFI Plant — 750 kVAR: A 750 kVAR automatic Power Factor Improvement plant continuously monitors the facility's reactive power consumption and corrects it in real time — eliminating reactive energy penalties on utility bills, protecting the transformer from unnecessary reactive current loading, and keeping the facility's power quality consistently high across all shifts and load conditions.

System Testing & Commissioning: Every element of the installation — transformer, switchgear, distribution panels, and PFI plant — was subjected to thorough testing and commissioning before handover. Protection settings were verified, metering accuracy confirmed, and the entire system validated for safe, stable operation — ensuring HAL Raktokorobi received a substation ready to perform from the moment it was energized.

The Result

A fully commissioned, right-sized 1250 kVA commercial substation that delivers exactly what HAL Raktokorobi's Dhaka facility needs: uninterrupted power, improved power quality, reduced energy costs, and a system built for long-term electrical stability. No overengineering, no compromise — just a precise, professional power solution delivered end-to-end by POWERtrac.

In Dhaka's demanding commercial environment, reliability isn't a feature. It's the baseline. And this substation delivers it.
