Transformer bushings don’t make headlines, until they fail. And when they do, the consequences can be devastating. Bushing failures account for approximately 20% of all transformer failures worldwide, making them one of the main causes of unplanned transformer outages...
Dynamic Ratings strengthens its APAC presence with a new facility featuring a training center, warehouse, and expanded local support.
The exponential growth of artificial intelligence and cloud computing has created an insatiable demand for data processing power. This surge has resulted in massive data centers that function as concentrated sources of nonlinear electrical loads that is altering the harmonic landscape of local power grids nationwide...
Your SF6 alarm goes off, and the maintenance crew rushes to the substation to discover that the ‘emergency’ was caused by the cold weather dropping the gas pressure, not a gas leak. Meanwhile, a real leak that's been slowly releasing this potent greenhouse gas goes undetected for weeks because it hasn't triggered the alarm threshold yet...
Utility asset managers face a hidden enemy that silently affects their most valuable assets. It doesn’t announce itself with alarms but slowly and quietly works at degrading transformer insulation, accelerating aging at an alarming rate. Studies have shown that with every 1% increase in moisture, the transformer aging rate doubles. Moisture doesn’t just compromise your transformer’s performance...
Network overloading, supply chain disruptions, and financial constraints are just the tip of the iceberg when considering the numerous factors that impact electrical assets. Emerging energy technologies are placing new demands on transformers’ traditional load. Supply chain limitations have led to extended lead times, and maintenance expenses continue to rise annually...
In today’s increasingly complex power generation environments, the reliability of high-voltage rotating equipment is critical to maintaining uptime and operational safety. Turbine generators, isophase bus ducts, and generator step-up (GSU) transformers are central to this infrastructure, working in unison to transmit immense electrical loads under demanding conditions...
Dynamic Ratings partners with different universities to help develop the next generation of engineers. During the 2024-2025 school year, Dynamic Ratings sponsored a senior design project at Milwaukee School of Engineering (MSOE) focused on partial discharge (PD) detection...
Transformers are among the most critical—and costly—assets in the electrical grid. Yet many failures occur without warning, often between routine maintenance cycles. That’s where Dissolved Gas Analysis (DGA) comes in. DGA monitoring gives utilities a window into the internal condition of a transformer without interrupting service. Operators can detect faults in their earliest stages...
