You Asked for a 100 kVA Transformer. Why Didn’t We Quote It Immediately?

The email looks simple

A buyer sends a familiar message: “Please quote one 100 kVA transformer and send the price as soon as possible.”

The fastest response is easy: ask for primary voltage, secondary voltage, and start pricing. But a fast quotation is not the same thing as a usable quotation. Many transformer problems begin before the drawing stage, when one unverified number is allowed to become the specification.

Remember this first

“We need 100 kVA” does not necessarily mean the system actually needs 100 kVA.

Before price, TransformerGrid wants to know where that 100 kVA came from.

A kVA number is only the top line

Transformer capacity sits on top of the real operating system. Behind that single number are actual load, power factor, single-phase or three-phase configuration, simultaneity, motor starting, future expansion, ambient conditions, altitude, nonlinear loads, and protection coordination.

If none of those conditions has been checked, a quotation may be quick but the project is not more certain. Two opposite errors are common: the transformer is undersized and struggles when the real load arrives, or it is oversized because “bigger must be safer,” pulling extra cost and downstream design changes into the project.

What we ask before we push the RFQ forward

• major load list
• kW/kVA and power factor, or equipment nameplate photos
• which loads operate at the same time
• large motors, compressors, pumps, UPS, VFD or rectifier loads
• single-phase or three-phase system
• primary and secondary voltage
• single-line diagram or existing-site photos
• future expansion plan

The better buying question

Do not ask only, “What does a 100 kVA transformer cost?” Ask, “Based on my load and operating mode, is 100 kVA a reasonable starting point, and what information is still missing?”

Price should follow a clarified specification. A specification should not be reverse-engineered from the first price you receive.

Where TransformerGrid fits

TransformerGrid does not simply forward a manufacturing partner’s number. We help organize the buyer’s application data into an RFQ that a manufacturing partner can actually review, then coordinate specification clarification, drawings, documents, FAT-related information, quotation, and delivery requirements.

That does not replace the EPC, consultant, utility, or owner’s engineer. It helps move questions that would otherwise appear during drawing approval, production, or site work back toward the inquiry stage.

Send the information you already have

If you only know that the project is “around 75, 100, 150, or 500 kVA,” you do not need a perfect specification before contacting us. Send the load list, single-line diagram, equipment nameplates, or a photo of the existing transformer.

We can help turn the available information into a clearer RFQ discussion before pricing goes too far.

Before asking what it costs, confirm whether it can actually work in your system.
