What We Review

What Project Information Can We Review?

Send the project files you already have. We review the key technical information for your transformer and switchgear selection, including ratings, system configuration, installation conditions, testing requirements and project documents.

Technical Specification

Specifications usually cover project standards, ratings, accessories, testing and document requirements. We help review:

  • Applicable standards
  • Voltage ratings
  • Capacity or rated current
  • Required accessories
  • Testing requirements
  • Project documentation requirements

Single-line Diagram / SLD

Your SLD shows the power distribution structure and equipment arrangement. We help review:

  • Transformer position
  • MV and LV switchgear lineup
  • Incoming and outgoing feeders
  • Bus coupler arrangement

  • Voltage levels

Transformer Datasheet

If your transformer parameters are not fully confirmed, we check the main items before preparing a proposal. We help review:

  • Rated capacity
  • Primary and secondary voltage
  • Vector group
  • Impedance

  • Accessories
  • Routine and special test requirements

Panel Schedule / Load Schedule

These define your switchgear configuration and feeder requirements. We help review:

  • Feeder quantity
  • Breaker ratings
  • Load types
  • Motor feeders

  • Cable entry direction

Site or Installation Requirements

Installation conditions affect equipment structure, enclosure, accessories and layout. We help review:

  • Indoor or outdoor installation
  • Ambient temperature
  • Altitude
  • Humidity
  • Coastal or corrosive environment
  • Room layout
  • Cable entry
  • Foundation requirements

Testing And FAT Requirements

Testing requirements should be clear before production and project submission. We help review:

  • Routine tests
  • Type test reports
  • Special tests
  • FAT requirements
  • Witness test requirements
  • Third-party inspection
  • Test reports and certificates

You don't need a complete technical package before contacting us. Send the available files first, and we'll help identify what needs to be confirmed next.

How It Works

How Our Engineering Support Works

Start with the files you already have. We work through your technical requirements step by step, clear up anything that's missing, and prepare a proposal based on the scope you confirm.

Sending transformer and switchgear project files for review
01 Step One

Send Your Project Files

Send whatever you have on hand: specification, single-line diagram, datasheet, load schedule, panel schedule, drawings or document list. No need to finalize every technical detail first. Partial files are enough to get started.

Send Your Files
Engineer reviewing transformer ratings and switchgear configuration
02 Step Two

Technical Review

Our engineers go through the parts that decide your equipment: ratings, product configuration, applicable standards, installation conditions, testing and document requirements. We check how it all fits your transformer or switchgear project.

Request A Review
Clarifying missing technical information with the customer
03 Step Three

Clarify What's Missing

When something isn't clear, we come back with specific questions instead of guessing. That might be fault level, cable entry, control voltage, IP rating, transformer impedance, vector group, component preference, FAT requirements or the project documents you need.

Preparing a technical proposal with datasheet and drawings
04 Step Four

Technical Proposal

Once the main requirements are confirmed, we put together a proposal that fits your project. Depending on scope, you get product configuration, datasheet, quotation, preliminary drawings and a document list, ready for your technical review.

Request A Proposal
Confirming key parameters and drawings before production
05 Step Five

Drawing Confirmation Before Production

Before anything goes into production, we confirm the key parameters and drawings with you. This is where we catch selection mistakes, drawing mismatches, installation issues and handover risks, while they're still easy to fix.
