What the study covers
- Network survey: generators, switchboards, transformers, cables and protections
- Short-circuit current calculations at key points of the network
- Check of breaker interrupting ratings and equipment withstand
- Protection coordination, so only the breaker closest to the fault trips
- Setting and equipment recommendations, documented in a report
When to do a short-circuit study
- Before a main switchboard replacement
- After adding a generator, a transformer or large drives
- When unexplained trips cut more circuits than expected
- When protection documentation is missing or outdated
From study to installation
Results feed directly into our electrical drawings, panel fabrication and commissioning tests.
Frequently asked questions
Why do a short-circuit study on a vessel?
To check that every breaker can interrupt the possible fault current at its location, and that protections are coordinated to isolate only the faulted section.
Should the study be redone after changes?
Yes, when a major source such as a generator, transformer or switchboard is added or replaced, because fault currents change.
