Power System Study and Analysis in Egypt | Carelabs

Power system study and analysis solves the power flow equations that govern your electrical network, verifying that generators, lines, transformers, and shunt elements perform as intended, withstand expected stress, and are protected against failures. For an Egyptian facility this brings together load flow analysis, short-circuit and fault analysis, and relay coordination — confirming both normal operating conditions and how the network behaves during a fault. Carelabs performs the full study in ETAP and delivers findings aligned with the Egyptian Code for Electrical Installations (ECP).

Your equipment was rated for a weaker network

Distribution networks are reinforced as demand around you grows. Available fault current rises, and switchgear specified against the original supply can become inadequate without anything inside your boundary changing.

What We Deliver

Fault duties against installed ratings

Fault currents are calculated at every bus to IEC 60909 and compared against nameplate interrupting capacity, with each shortfall quantified as a margin rather than reported as a flag.

WHY IT MATTERS

An under-rated device does not trip late

A breaker asked to interrupt more than its rating can fail to clear at all, leaving the fault to burn until something upstream removes it. Nothing in normal operation reveals that the margin has gone.

  • Fault level obtained from the supply authority for the actual point of connection rather than inferred from transformer rating.
  • Maximum and minimum source conditions both calculated, since maximum governs equipment withstand and minimum governs protection pick-up.
  • Devices relying on cascade or back-up protection checked against the manufacturer's tested combination tables rather than curve overlap alone.
  • Cable and busbar withstand assessed against actual clearing time, because a conductor adequate on continuous current can fail the fault-energy check.
  • Equipment whose rating cannot be established identified explicitly, since it cannot be shown adequate and that is itself a finding.

How the study runs

01

Survey and reconcile

A lead engineer walks the installation and reconciles the single line diagram against it, recording every discrepancy for the drawing set.

02

Identify the equipment

Devices without accessible rating data are identified from physical characteristics and manufacturer archives wherever those still exist.

03

Obtain the supply data

Fault level at the point of connection is requested from the supply authority in both maximum and minimum conditions.

04

Model and calculate

The network is built in ETAP and fault duties are calculated at every bus across the switching configurations the site operates.

05

Compare and rank

Duties are compared against installed ratings and shortfalls are ranked by consequence, which is what makes a staged plan possible.

06

Report and hand over

Findings, options and the calibrated model are handed over with a walkthrough for your engineering team.

Frequently asked questions

Because the supply may have changed. Networks are reinforced as surrounding demand grows, which raises the fault current available at every connection on them. Switchgear specified against the original supply can fall below the new duty with nothing inside your installation having been altered, and normal operation gives no indication.
It can usually still be identified from casting marks, frame dimensions, internal components and manufacturer archives. Where a rating genuinely cannot be established, that is reported as a finding rather than filled with an assumption, because equipment that cannot be shown adequate cannot be relied on in a fault.
By consequence rather than by the size of the shortfall. A device that is marginally under-rated on a lightly used circuit is a different proposition from an incomer with no margin at all. The report ranks findings so a staged programme addresses genuine risk first rather than the cheapest items.
Usually yes, because it shares the model and the site survey, which are the expensive parts. Fault duty tells you whether equipment survives abnormal current; load flow tells you whether the network carries normal demand at acceptable voltage. Commissioning them together costs far less than separately.
