Busbar & Layout Design
AIS and GIS busbar arrangement design, phase clearance calculations and equipment layout for optimal site footprint.
Insulation Coordination
Overvoltage study, BIL/SIL selection, surge arrester specification and insulation coordination reports per IEC 60071.
Equipment Sizing & Selection
Rating calculations for transformers, circuit breakers, disconnectors, earthing switches, CTs, VTs and surge arresters.
Earthing System Design
Touch and step voltage analysis, earth grid design to IEEE 80 / IS 3043, earth mat conductor sizing and layout drawings.
Detailed Engineering Drawings
GA drawings, foundation loading schedules, equipment arrangement plans and as-built documentation for all primary plant.
Our Process
FROM CONCEPT TO DETAILED DESIGN
01
CONCEPTUAL DESIGN
Review of client specifications, grid code requirements and site constraints. Develop concept SLD and equipment list for client approval within 2 weeks of award.
02
PRELIMINARY ENGINEERING
Prepare preliminary equipment datasheets, layout drawings and load flow analysis. Submit for client and utility review, incorporating comments before progressing.
03
DETAILED ENGINEERING
Produce IFC drawings including SLDs, GA layouts, earthing designs, cable schedules and equipment specifications to applicable standards.
04
VENDOR DOCUMENT REVIEW
Review supplier drawings and technical submittals for transformers, switchgear and protection equipment ensuring compliance with project specifications.
05
AS-BUILT & DOCUMENTATION
Compile final as-built drawings, design calculations, test reports and O&M manuals for handover to client and utility authority.
