15 kVA Single-Phase Pad-Mounted Transformer

Each transformer is configured according to the approved project specification. Primary voltage, secondary voltage, feed arrangement, insulation level, tap requirements, accessories and applicable standards must be confirmed before quotation and production.

15 kVA Single-Phase Pad-Mounted Transformer: Listed Product and Project Requirements

• Listed Capacity: 15 kVA
• Phase: Single-phase
• Product Type: Liquid-filled pad-mounted distribution transformer
• Installation: Outdoor, pad-mounted

Requirements to provide for engineering review

• Frequency: State the required site frequency, including 60 Hz where specified by the project.
• Primary Voltage: Provide the system voltage, phase-to-neutral voltage where applicable, grounding arrangement and utility specification.
• Secondary Voltage: State the required output voltage and connection arrangement.
• High-Voltage Interface: State any dead-front or live-front requirement and the required cable interfaces.
• Tap Requirements: Provide the specified tap range and increments, or mark TBC for review.
• Feed Arrangement: State the radial-feed or loop-feed requirement.
• Insulation Level: Provide the required BIL and primary voltage class, or mark TBC for review.
• Insulating Liquid: State any specified liquid and relevant environmental or fire requirements.
• Standards and Edition: Provide the project or utility specification. If IEEE C57.12.38-2025 is required, its scope and the proposed equipment must be reviewed together.

These inputs define the requested equipment. Available configurations, conformity, test evidence and supply scope require confirmation for the proposed design. A standard reference alone does not establish product conformity.

Applications

This transformer may be considered for smaller residential properties, small commercial facilities, project auxiliary loads and other underground single-phase distribution applications.

Final suitability depends on the load calculation, system voltage, installation environment and applicable utility requirements.

Can 15 kVA serve a small property?

The site description alone does not determine capacity. Provide the connected loads, expected simultaneous demand, and proposed service voltage so the 15 kVA rating can be reviewed against the actual project.

Engineering Review

The voltage ratio, BIL, tap arrangement, terminal configuration, enclosure, insulating liquid, protection requirements, accessories and applicable standard will be reviewed for each project.

The product image illustrates this transformer family. Final enclosure dimensions and terminal layout must follow the approved project drawing.
