Quality you can trust

MHR operates a fully integrated design and manufacturing facility dedicated to producing high‐quality transformers for industrial, utility, and renewable‐energy applications. Our engineering team develops custom solutions using advanced design tools, precision manufacturing processes, and strict quality‐control systems. 

The facility is equipped for complete in‐house fabrication, assembly, and testing, ensuring every transformer meets CSA, UL, and other international standards. With a focus on reliability, efficiency, and technical excellence, MHR delivers tailored transformer solutions built to perform in demanding environments and diverse project requirements.

MHR Power delivers comprehensive project planning services that establish a clear foundation for successful execution. 

Our team defines project scope, technical requirements, timelines, and resource needs with precision, ensuring alignment across all stakeholders. Through detailed scheduling, risk assessment, and coordination with engineering, manufacturing, and field teams, we create structured plans that support efficient workflows and predictable outcomes. 

This disciplined approach enables MHR Power to deliver projects on time, within budget, and to the highest standards of quality and reliability.

Every MHR Power transformer undergoes a comprehensive series of Factory Acceptance Tests (FAT) to ensure safety, reliability, and long‑term performance. Our testing program follows CSA, IEEE, and international standards, verifying that each unit meets the highest engineering and operational requirements.

Some of the Key Tests Performed During Manufacturing includes and limited to:

• Impulse Test (up to 250 kV)   Validates the transformer’s ability to withstand lightning surges and switching transients.
• Partial Discharge Test   Conducted in accordance with CSA & IEEE standards to ensure insulation integrity and long‑term dielectric performance.
• Temperature Rise Test   Confirms thermal stability under full‑load conditions and verifies that the transformer can operate safely within its designed temperature limits.
• Applied Voltage Test – Ensures insulation strength between windings and ground.
• Induced Voltage Test – Verifies turn‑to‑turn insulation and withstand capability.
• Winding Resistance Measurement – Confirms proper conductor sizing and connection integrity.
• Ratio & Polarity Tests – Ensures correct voltage transformation and phase alignment.
• No‑Load & Load Loss Measurements – Validates efficiency and core performance.
• Insulation Resistance (Megger) Test – Confirms insulation health and moisture resistance.

At MHR Power, safety is the foundation of every manufacturing process we undertake. We maintain a controlled, compliant, and continuously improving work environment where every product is built with precision and every team member operates with safety as a core responsibility. 

Our facilities follow strict protocols for material handling, assembly, testing, and workflow execution, ensuring full adherence to CSA, UL, and other international standards. Through rigorous training, proactive risk management, and disciplined operational practices, we protect our people, our partners, and the integrity of every transformer and power‐distribution solution we deliver.

Safety isn’t just a requirement at MHR Power—it’s a commitment embedded in our culture and our craftsmanship.
