Project completedWhy Stealth
The name is the promise: a power system you never have to think about.
Engineering decisions you can defend, on paper and on site.
Every recommendation we make is backed by calculation, modelled on your real operating conditions, and free of any link to an equipment supplier. You get the right system for the job, at the right cost.
02Mission-critical reliability
Designs built around continuity of supply, for facilities where an outage is measured in lost revenue or lost safety.
0315+ years in industry
Hands-on experience across heavy industry, data centers and high-value developments, not only in the design office.
04Lower CAPEX and OPEX
Right-sized transformers, switchgear and generation, so you stop paying for margin you don't need, without giving up reliability.
05Built on your real conditions
Load nature, power quality and process requirements drive the design, rather than generic rules of thumb.
06Long-term continuity
Systems planned for expansion, maintenance and future technology, with support that continues after energization.

This is an 11 kV plant fed from a 66 kV utility. Inject a fault on any feeder. With proper coordination, only the nearest breaker trips. Then switch to "poorly coordinated" and try again.

System healthyPick a feeder and inject a fault.

Engineering tools
Simplified versions of the studies we run. Real projects use your actual data.
Three questions every facility owner should ask. Try them.
Is my switchgear strong enough? Am I paying for a transformer I don't need? Will my data center survive a failure? Change the inputs and watch the answer update.
Simplified estimate at the 0.4 kV main switchboard, for illustration. A real short-circuit study follows IEC 60909 with your actual network data.

UNDERSIZED · UNSAFE
The switchboard cannot safely interrupt this fault. Instead of clearing it, it can explode or catch fire.
Price assumptions (edit)
Example prices for illustration only. Losses use typical oil-transformer values and a 0.4 loss-load factor.

Power-system studies
Calculated, documented,
decision-ready.
The calculations behind every decision.
A robust decision starts with accurate studies. Each one answers a specific question about your system, and each ends in a structured report your team can act on.
| Ref. | Study | The question it answers |
|---|---|---|
| ST-01 | Load flow | Are voltages, loading and losses within limits in every operating case, including contingencies? |
| ST-02 | Short circuit | What fault levels will each bus see, and are switchgear and cables rated to withstand them? |
| ST-03 | Motor starting | Can large motors start without unacceptable voltage dips on the rest of the plant? |
| ST-04 | Protection coordination & TCC | Will the nearest device clear a fault first, so only the faulted section loses power? |
| ST-05 | Protective device review | Are existing relay settings and device characteristics still correct for today's system? |
| ST-06 | Load analysis & power quality | What does the load really demand, and what continuity and quality level does the process need? |
