What is EcoStruxure Transformer Expert?

EcoStruxure Transformer Expert is your transformer asset advisor solution which offers real time transformer health monitoring. The solution gathers data from our smart IOT sensor, offline gas analysis, transformer configuration and the historic & future load of the asset. Using this information, our smart algorithms perform trend analysis, forecasting and risk assessment. This information is then used to provide insights and recommendations about the transformer.

EcoStruxure Transformer Expert utilizes the integrated sensors (temperature, moisture, PD, vibration & hydrogen) and its smart algorithms, developed based on IEEE, IEC, and CIGRE standards, as well as research papers, to detect abnormal behavior in a transformer's health.

The solution consists of two parts: (1) EcoStruxure Transformer Expert Probe and (2) Dashboard.

(1) EcoStruxure Transformer Expert Probe

The EcoStruxure Transformer Expert hardware is capable of measuring key transformer parameters and transmitting the information to our dashboard, where it is analyzed and displayed in a graphical format. There are five different sensors integrated into the probe of the device to measure:

• Water Activity
• Temperature
• Partial Discharge
• Vibration
• Hydrogen (Optional)

Basic Model: EcoStruxure Transformer Expert

Hydrogen Model: EcoStruxure Transformer Expert with H2 Dual Sensor

How is EcoStruxure Transformer Expert Probe installed?

The EcoStruxure Transformer Expert Probe is installed in an oil valve to facilitate continuous monitoring. The interface with the oil valve is via a 3/4" female thread. Depending on the type of oil valve, you may need additional hardware items to install ETE.

To learn about the complete installation procedure please visit our EcoStruxure Transformer Sensor Planning Guide & EcoStruxure Transformer Expert Probe Installation User Manual.

Does the sensor need in-field calibration and what is the warranty?

The EcoStruxure Transformer Expert Probe is a factory calibrated solid state sensor and requires no field calibration. The solution has lifetime warranty under valid subscription.  To learn more, please visit our article: How are sensors in the EcoStruxure Transformer Expert calibrated?

(2) EcoStruxure Transformer Expert Dashboard

The EcoStruxure Transformer Expert Dashboard is the web-based application where all the information from the sensor can be viewed. The dashboard algorithms are supported by IEEE & CIGRE standards and are capable of a range of data analytics. The results are then displayed in graphical and tabular formats. Customers have access to fleet wide health visibility, forecasting, insights and recommendations.

How does the sensor communicate and is it secure?

Communication with The Dashboard:

The sensor transmits via local 3G/4G network and comes with fully provisioned telecommunication functions requiring no configuration effort at installation time. Good 3G/4G signal strength is vital for successful communication. If 3G/4G signals are not available at the site, our team can discuss alternative options.

Cyber Security:

Schneider Electric has designed the IoT data transfer processes, storage, access and management operations to be compliant with the EU Power Utility Data Security requirements. The security architecture protects customer data using four key features. To learn more, please visit our article: How does the solution protect my data from cyber security threats?

What benefits can we expect?

There are many ways customers can benefit from the EcoStruxure Transformer Expert:

• Capital savings by extending the life of a transformer and therefore delaying the costs associated with replacement.
• Detection of minor failures which can be fixed before they develop into major/catastrophic failures.
• Overall health monitoring, allowing asset managers to determine if overloading the transformer is safe. The amount and duration of overloading is highly dependent on the transformer. Overloading a transformer too much or for too long can also cause damage, so it's crucial to understand what the transformer is capable of.
• Reduction in the probability of transformer failure in a manufacturing plant.
• Reduction in the probability of transformer failure in a power generation plant.
• Reduction in the frequency of offline DGA. This is particularly valuable in cases where a transformer is in a remote or difficult location and oil sample collection is costly.

These savings can be approximated using our ROI Tool.
