understanding transformer failures
Transformers are crucial assets to the power grid but are prone to hidden failures. VIE Technologies combines advanced sensing with predictive analytics to detect subtle patterns and anomalies in transformer behavior that traditional monitoring overlooks—replacing guesswork with real-time intelligence and and enabling proactive, condition-based maintenance.
The VIE sensor installs directly on the outside of the transformer—no need to open, modify, or power down the equipment. Compact and discreet, the sensor is less than 2 inches in diameter and can be installed in minutes without interrupting operations. It’s a low-impact, high-value solution designed for seamless integration into your existing infrastructure.
The VIE sensor is a compact, non-invasive device that brings AI-powered intelligence to transformer monitoring. Installed in minutes with no need to open or power down equipment, the 2-inch sensor continuously captures triaxial vibration, temperature, and electrical stress data - delivering real-time insights with zero disruption.
electrical failures
Electrical failures in transformers often stem from abnormal current conditions. These issues can lead to core saturation, overheating, increased energy losses, and accelerated insulation degradation, ultimately threatening the transformer's operational stability and lifespan. VIE’s system continuously monitors power quality, current waveforms, and magnetic conditions at a granular level. This enables early detection of harmful trends far sooner than traditional methods.

mechanical failures
Mechanical failures occur due to structural weaknesses or physical stress within the transformer. Repeated load fluctuations and external impacts can weaken internal components over time. These issues create instability, increase internal strain, and elevate the likelihood of electrical faults and long-term degradation. VIE detects minute structural changes and abnormal vibration signatures well before they manifest as audible noise or major mechanical faults.

failures
Thermal failures are often caused by overloading, cooling inefficiencies, or internal faults, leading to excessive heat, fluid degradation, and gas formation. These conditions accelerate the aging of insulating materials and increase the risk of transformer failure. VIE's thermal monitoring system identifies abnormal heat patterns and gas buildup at the earliest stages, enabling proactive intervention to prevent costly downtime and catastrophic failure.
