Protection & Controls

When a fault strikes your feeder at 3am, the difference between a minor event and a catastrophic failure comes down to one thing: your protection system. At PACS, protection engineering is not a side service - it is our entire reason for being.

Our Kahramaa-licensed engineers - holding P1, P2, and P3 designations - deliver protection solutions of absolute integrity, from the initial relay settings calculation and schematic design through pre-commissioning, live commissioning, and final regulatory approval. We work across every voltage tier, from 220kV EHV transmission down to LV distribution panels, and across every major relay platform deployed in the market today. Every schematic we produce, every setting we calculate, and every test we execute is backed by decades of grid-level experience and an uncompromising commitment to getting it right the first time.

Frequently Asked

Answers to the questions our clients ask most often before engaging our team.

Are you Kahramaa approved?

Yes, unconditionally. We hold Kahramaa P1, P2, and P3 protection engineering licenses and have passed Kahramaa inspection on every single project we have delivered. Our approval record is unbroken.

Can you commission differential protection on live, energized systems?

Yes. We have done so successfully on multiple projects, including the FIFA Al Rayyan Stadium and ISF. Commissioning differential protection on load demands precision, experience, and nerve, these are qualities our engineers bring to every site.

Do you handle the full process or just the testing phase?

We provide complete end-to-end engineering: from the initial protection design and relay settings calculation through pre-commissioning, live testing, Kahramaa inspection coordination, and the full handover documentation package. You engage us once, and we see it through to energization.
