Engineered for Low-Harmonic, High-Integrity Power

We are pleased to introduce our new 500 kVA, 3-phase, 12-pulse transformer, designed for clean and highly stable power conversion in harmonic-sensitive environments.

Built around an 11 kV primary with dual 690 V phase-shifted secondaries and enclosed to IP23, the unit delivers exceptionally low THDi by cancelling dominant harmonic orders at source. This improves upstream power quality and supports long-term system reliability.

Technical Configuration & Electrical Performance

Primary & Secondary Voltage Design

• Primary Voltage: 11 kV

• Secondary Voltage: Dual 690 V (phase-shifted)

• Power Rating: 500 kVA

• Phase: 3-Phase

• Enclosure Rating: IP23

The dual 690 V phase-shifted secondary configuration enables harmonic cancellation, significantly reducing Total Harmonic Distortion (THDi) without the need for complex external filtering.

Reducing Harmonics at Source

The 12-pulse transformer architecture is specifically designed to cancel dominant harmonic orders within high-load systems.

By mitigating harmonics at source, this transformer:

• Improves upstream power quality

• Reduces stress on generators and switchgear

• Enhances system efficiency

• Supports long-term asset reliability

This makes it ideal for installations where electrical integrity is essential.

Applications for High-Duty Industrial Environments

This transformer platform has been developed for demanding applications, including:

• Large Variable Speed Drive (VSD) installations

• Data centre infrastructure

• Marine shore power systems

• Renewable energy projects

These environments require stable voltage delivery, harmonic control, and resilient power conversion under continuous load.

Supporting UK Electrification & Industrial Decarbonisation

As the UK advances toward widespread electrification and industrial decarbonisation, demand for low-distortion, high-efficiency transformer solutions continues to grow.

This 500 kVA 12-pulse transformer provides a robust, low-harmonic interface for next-generation:

• Energy infrastructure

• Marine electrification

• Automation systems

• Industrial power upgrades
