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.
We produce HV and MV substation documentation — single-line diagrams, physical layouts, protection schemes and IEC 61850 automation documentation — for greenfield and brownfield transmission, distribution, mining and industrial substations up to 500 kV. Drawings are prepared in Microstation or AutoCAD to the IEEE, IEC or AS 2067 requirements your project uses.
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.
- Transmission substations up to 500 kV
- Distribution substations: 33 kV, 11 kV, 6.6 kV
- IEC 61850 substation automation documentation
- Protection coordination, arc flash, short-circuit studies
- Utility-grade drawing standards and title blocks
- Scope and review requirements agreed before production
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.
Start with a defined scope.
Agree the source information, deliverables and review requirements before the first issue.
Your team. Our team.
A clear way to work.
Agree the standards, review responsibilities and working arrangements before the first issue.
Quality: who checks the drawings?
The checking brief covers the project standard, drawing references and review responsibilities. We agree the internal checks, client review sequence, revision allowance and response windows as part of the package scope.
Standards: will you draw to our codes and templates?
We work to the standard that applies to your project: NEC (US), IEC 60364 and IEC 61439, AS/NZS 3000 (Australia and New Zealand), CSA C22.1 (Canada) and BS 7671 (UK). We draw inside your title blocks, layer conventions, cell and block libraries, not ours.
IP and NDA: what happens to our files?
Confidentiality and file access are agreed before source material is shared. Tell us if you require an NDA or a client-managed workspace, VDI or VPN. The scope identifies the permitted environment, access arrangements and handover requirements.
Stamps: who signs the drawings?
If your package requires a PE, Chartered Engineer or other statutory sign-off, tell us during scoping. We agree the responsible party and review requirements before production starts.
Time zones: when can we talk to the team?
Our production team is based in Pakistan (PKT, UTC+5). We agree your project’s working hours and handover arrangements during scoping. The table below uses a 09:00–18:00 PKT reference window to help plan the overlap; it is not a committed project schedule.
| Your time zone | Reference window, your clock | Overlap with your 09:00–17:00 |
|---|---|---|
| Perth — AWST (UTC+8) | 12:00–21:00 | 5 h (12:00–17:00) |
| Brisbane, Sydney — AEST (UTC+10) | 14:00–23:00 | 3 h (14:00–17:00) |
| Dubai — GST (UTC+4) | 08:00–17:00 | 8 h (09:00–17:00) |
| London — GMT (UTC+0) | 04:00–13:00 | 4 h (09:00–13:00) |
| New York — ET (EST, UTC−5) | 23:00–08:00 (overnight) | None — overnight handover |
| Los Angeles — PT (PST, UTC−8) | 20:00–05:00 (overnight) | None — overnight handover |
Daylight saving: Sydney, Melbourne, Canberra and Hobart move to AEDT (UTC+11) from October to April, cutting the overlap to 2 h (15:00–17:00); Queensland and Western Australia stay on standard time. UK summer time (BST, UTC+1) widens the London overlap to 5 h (09:00–14:00). US daylight time moves our day to 00:00–09:00 EDT and 21:00–06:00 PDT, so US teams can plan an overnight handover; the actual arrangement is agreed for your project.
