Substation design outsourcing — HV & MV documentation.

Single-line diagrams, physical layouts, protection schemes, and IEC 61850 automation documentation for transmission, distribution, mining, and industrial substations. Up to 500 kV.

IEEE C37 / C57 IEC 61850 AS 2067 Microstation / AutoCAD ETAP Protection

§01 — Overview

Substation documentation lives longer than the engineer who drew it.

Substation drawings are referenced for decades. Protection settings ripple through the whole network when one bus changes. Control schematics are the first thing a commissioning engineer pulls at 3am during a relay trip.

Our substation design outsourcing covers the full spectrum — transmission to distribution, greenfield to brownfield, IEEE to IEC. Every deliverable produced to utility-grade standards and client-specific conventions.

Distribution substations: 33 kV, 11 kV, 6.6 kV
IEC 61850 substation automation documentation

§02 — Deliverables

Substation drawings we produce

Single-Line Diagrams

Transmission and distribution SLDs with full protection, metering, and control notation per IEEE / IEC convention.

Physical Layouts

General arrangement, plan views, elevations, and section drawings for outdoor and indoor substations.

Protection Schematics

Relay schematics, trip/close logic, and protection-panel wiring per client standards and IEEE C37.

Control Schematics

Control schematics, AC/DC distribution, station-service schematics, and marshalling-cabinet detail.

IEC 61850 Automation

SCD and ICD file review, IED configuration documentation, station-bus architecture drawings.

Protection & Coordination

Relay coordination studies, arc flash analysis, short-circuit calculations in ETAP or SKM Power Tools.

Test us on one substation SLD or protection schematic.

Free first delivery, to IEEE/IEC/client standard, inside your title block. If it doesn't meet your utility's internal quality gate, no invoice.

We can afford this because our protection schematics routinely pass utility QA on first issue.

§03 — FAQ

Substation-design questions

What voltage classes do you cover?

Up to 500 kV for transmission substations; 33 kV, 11 kV, and 6.6 kV for distribution and industrial substations; 400 V / 480 V LV distribution.

Do you handle IEC 61850 substation automation?

Yes. SCD and ICD file review, IED configuration documentation, and station-bus architecture drawings for IEC 61850-compliant substations.

Can you do greenfield and brownfield substations?

Both. Greenfield: new substation SLD, physical layout, and protection design. Brownfield: as-built updates, protection re-setting documentation, and refurbishment drawings.

Do you produce client-specific standards?

Yes. We work inside utility-specific template libraries from the engagement start. Our teams maintain client-specific cell libraries, title blocks, and protection-panel conventions per active engagement.

What turnaround can we expect?

Simple distribution substations: 2–4 weeks for complete documentation. Transmission substations (132 kV+): 6–12 weeks depending on complexity and scope.

Substation-grade documentation without new hires.

First drawing free. IEEE/IEC compliant. Inside your template library.
