Electrical Design Consultancy & Engineering Solutions

Flawless electrical design is the foundation of any safe, reliable, and energy-efficient industrial or commercial facility. Poorly sized cables, inadequate switchgear ratings, or uncoordinated protection philosophies lead to frequent power interruptions, severe voltage drop, electrical fire risks, and expensive retrofits. At iPower Switchgear, we deliver premier Electrical Design Consultancy Services for manufacturing plants, chemical units, commercial real estate, and utility substations across Ahmedabad, Gujarat, and pan-India.

Our team of chartered electrical design engineers prepares complete engineering packages from conceptual design through detailed engineering to commissioning supervision. We utilize advanced CAD and power system simulation software to engineer Single Line Diagrams (SLDs), electrical load lists, cable schedules, equipment specifications, and protection coordination schemes compliant with IS, IEC, IEEE, and National Electrical Code (NEC) standards.

Scope of Electrical Design Consultancy Deliverables

  • Single Line Diagram (SLD) Engineering: Designing robust primary and secondary distribution SLDs including HT/LT switchgear, distribution transformers, DG sets, and emergency backup power sources.
  • Electrical Load List & Demand Sizing: Calculating connected load, maximum demand (kVA), diversity factors, and transformer sizing for DISCOM power sanction approval.
  • HT & LT Cable Sizing & Schedule: Sizing conductors based on continuous current rating, derating factors (ambient temp, grouping, soil), voltage drop limits, and short-circuit withstand capacity (I²t).
  • Substation & Equipment Specification: Drafting technical specs and data sheets for VCB panels, transformers, ACB PCC panels, MCCs, APFC panels, and UPS units.

Advanced Engineering Standards & Operational Quality

At iPower Switchgear, all Electrical Design Consultancy projects are executed in strict accordance with ISO 9001:2015 quality management procedures, Central Electricity Authority (CEA) safety guidelines, and applicable Indian & International standards (IS / IEC / IEEE). Our experienced team conducts on-site field audits, digital twin simulation modeling, and rigorous pre-commissioning checks to eliminate operational vulnerabilities.

Whether you are establishing a new industrial facility, upgrading existing sub-station infrastructure, or requiring emergency engineering support in Gujarat, our certified engineers deliver comprehensive technical documentation, stamped test certificates, and actionable recommendations to optimize long-term asset performance.

Comprehensive Engineering Deliverables & Design Workflow

Our electrical design consultancy follows a structured engineering workflow compliant with IS 732, IEC 60364, and NEC India:

  • Primary Distribution SLD & Protection Philosophy: Engineering main single-line diagrams detailing HT incomers, transformer protections, bus-coupler interlocks, and feeder ratings.
  • Load Balance & Diversity Calculations: Preparing comprehensive electrical load lists, diversity factor applications, and demand kVA sizing for utility power sanctioning.
  • Cable Sizing & Cable Schedule Generation: Calculating derated current ratings, voltage drop limits, and short-circuit thermal limits (I²t) for all power and control cables.
  • Statutory Compliance & Tender Package Preparation: Preparing technical specifications, Bill of Quantities (BOQ), and vendor drawing review packages for CEIG approval.

Primary Distribution Philosophy & Fault Discrimination

Our design team establishes a clear protection philosophy defining main-tie-main interlocking, main breaker interrupting requirements, neutral grounding resistor (NGR) sizing, and selective time grading margins between utility incomers and plant distribution feeders.

Tender BOQ Preparation & Contractor Bid Scrutiny

Our consultancy services include preparing detailed Bill of Quantities (BOQ), commercial tender documentation, and technical bid evaluations. We assist project developers in scrutinizing contractor proposals to guarantee high-quality equipment procurement.

Our consultancy services provide complete single-line diagrams, short-circuit calculations, and equipment specifications, ensuring smooth statutory approval with GETCO, CEIG, and local DISCOMs.

Frequently Asked Questions — Electrical Design Consultancy

What is included in an electrical design consultancy package?
An electrical design package includes single line diagrams (SLDs), electrical load balance sheets, HT/LT cable schedules, transformer/DG sizing calculations, short-circuit and protection philosophy documents, equipment datasheets, and bill of quantities (BOQ).
Why hire an independent electrical consultancy like iPower Switchgear?
An independent electrical consultant ensures unbiased equipment selection, optimizes energy efficiency, prevents supplier over-sizing, and guarantees strict compliance with IS/IEC safety standards and DISCOM approval norms.
Do your electrical designs comply with National Electrical Code (NEC) India?
Yes. All our electrical drawings, earthing layouts, cable tray routing, and protection schemes adhere strictly to NEC India, IS 732, IS 3043, and Central Electricity Authority (CEA) regulations.
Can iPower Switchgear handle statutory approvals for the design?
Yes. Our team handles DISCOM load sanctioning, CEIG drawing approval, and factory inspector safety sign-offs for the completed electrical design package.
