What is a fault level study and when do I need one?

A fault level study calculates the prospective short-circuit currents across a network so you can confirm switchgear and equipment are adequately rated. You need one whenever a connection, extension or reinforcement changes the fault infeed, and network operators expect it as part of a connection application.

What does a power system study package include?

A typical package combines load flow, fault level and protection coordination studies, with connection-support studies for G99 or the Grid Code where a connection is involved. Results are reported in terms a designer or network operator can act on, with assumptions and limitations stated plainly.

Do you provide the study models to the client or network operator?

Yes. Studies are produced in recognised power system analysis tools such as PowerFactory, IPSA and ETAP, and native models can be supplied on request, so the network operator or your own team can review and reuse them.

Services

Power system studies

Load flow, fault level, protection coordination and connection-support studies that put verified numbers behind design and connection decisions.

The problem this solves

Network operators, designers and developers need evidence, not assumptions: whether a network can carry the load, whether switchgear is adequately rated, whether protection will grade, and whether a connection will comply. An unverified assumption at study stage becomes an expensive discovery at commissioning.

Deliverables

Modelled and validated study reports produced in PowerFactory, IPSA, ETAP and other recognised power system analysis tools
Fault level and equipment rating assessments
Protection coordination and grading records
Native study models available on request
Study evidence packs for network operator submissions

How this reduces risk

Studies confirm ratings, settings and compliance before equipment is ordered or a connection agreement is signed. That protects against under-rated plant, non-grading protection and failed compliance demonstrations, each of which carries direct cost and programme consequences.

Why appoint Saqib Engineering

Our studies are produced by engineers who also design substations and protection schemes, so results are reported in terms a designer or network operator can act on, with the assumptions and limitations stated plainly.
