Introducing the URNR-TR-36: Our Latest VFTO-Resistant Voltage Transformer

At Arteche, we are committed to delivering cutting-edge solutions that enhance power system reliability. That’s why we are excited to introduce the URNR-TR-36, a dry-type outdoor voltage transformer designed for exceptional durability and safety in demanding environments.

Modern power systems face increasing challenges, from frequent switching operations to the integration of renewable energy sources. These conditions generate Very Fast Transient Overvoltages (VFTO), which can significantly impact transformer insulation. To address this, we developed the URNR-TR-36, specifically designed to withstand extreme voltage transients, ferroresonance, and harmonics, ensuring long-term stability and protection.

Proven Performance Through Rigorous Testing

We put the URNR-TR-36 through extensive validation, successfully passing a 360kV peak steep-front impulse test (>2500 kV/µs), conducted in accordance with CSA C411.1-16 by Powertech Labs Inc.. These tests confirm the transformer’s ability to operate safely under the most extreme conditions.

Advanced Materials and Smart Design

Encapsulated with Hydrophobic Cycloaliphatic Epoxy Resin (HCEP), the URNR-TR-36 offers superior resistance to tracking, erosion, and UV exposure, making it ideal for coastal and heavily polluted environments. Its compact, lightweight, and maintenance-free design makes it the perfect solution for metering, relaying, capacitor bank switching, and renewable energy applications.

Committed to Quality and Reliability

We adhere to the highest industry standards, ensuring the URNR-TR-36 meets IEEE C57.13, IEC 61869-1/2/3, and CAN/CSA C61869-1/3 certifications. This reinforces our dedication to delivering reliable, high-performance solutions for the evolving energy sector.

Powering the Future with Confidence

With the launch of the URNR-TR-36, we continue to drive innovation, helping power utilities and industrial operators build more resilient and efficient energy infrastructures. By combining proven VFTO resistance, cutting-edge materials, and certified performance, we provide a transformer that ensures safety, reliability, and long-term durability.
