A correct design is the foundation of a safe, efficient facility. SOREAS produces approved, calculation-based and authority-defensible electrical designs for your high-, medium- and low-voltage installations.
Calculation-based, buildable designs
We produce single-line diagrams backed by load-flow, voltage-drop and short-circuit calculations. Short-circuit currents follow IEC 60909-0:2016, cable cross-sections follow TS HD 60364-5-52 with a ≤5% voltage-drop criterion, and protection coordination is set on a selectivity basis.
Lighting, earthing and approvals
We design lighting to the TS EN 12464-1:2021 illuminance requirements, and earthing and lightning protection to the relevant standards. We complete OIZ and utility approval processes quickly with complete files and correct calculations.
It depends on scope and the authority's workload. With complete files and correct calculations, SOREAS completes approval as quickly as possible.
All of HV, MV and LV — end to end, from the substation to panel outputs.
Yes. We calculate short-circuit currents per IEC 60909-0:2016 and set breaker/fuse selection and selectivity into the design. These calculations are usually required for OIZ provisional-acceptance files.
Yes — for capacity increases, machine additions or compliance fixes, including as-built updates.
