Specify Transformers Like a Pro

Specifying a transformer might not be the flashiest part of your project, but get it wrong, and you’ll feel the pain fast.

At SES, we help you make the right call from the start. Our 5-step process removes guesswork, cuts downtime, and ensures long-term reliability.

Here’s how to get it right:

Step 1: Define Your Electrical Needs

Power Checklist:

✅ Load demands (kVA, kW, HP, or output Amps)

✅ Voltage – input and output

✅ Isolation requirements

✅ Additional features – ±% tappings, electrostatic screens, etc.

We start with the fundamentals, load, voltage, and any special requirements. Whether you’re working in horsepower or kilowatts, we’ll help you size it right the first time.

Step 2: Confirm Relevant Standards

Are there any specific Standards or Specs your transformer needs to meet?

SES builds to AS/NZS 60076 and 61558, and supports compliance with AS/NZS 3000 to make installation sign-off smooth. For industries like Rail or Defence, we’ll help ensure all regulatory boxes are ticked.

We guide you through what matters, so your transformer performs safely, efficiently, and compliantly from day one.

Step 3: Consider the Installation Environment

Indoor or outdoor? Harsh conditions? We’ll match the right enclosure, IP23, IP65, or something more specialised, to your site.

Outdoor-rated transformers aren’t just housed differently. They’re built to run cooler in sealed environments and withstand factors like solar loading.

Knowing this early avoids costly redesigns later.

Step 4: Evaluate Quality & Support

Not all transformers are built equal. Materials, testing, and standards compliance affect long-term performance. So does the supplier.

Look for test reports, FATs, schematics, and responsive support, before and after the sale. Ask suppliers how they back their product. It tells you a lot about what you’re really buying.

Step 5: Make an Informed Decision

Compare options by more than just price. Choose the transformer that fits your project goals, for today and tomorrow.
