Real-time visibility into transformer condition, fault gases, and changes in critical components
Transformer monitoring helps identify changes in the condition of critical power transformers in time before they begin to impact reliability, maintenance costs, or cause unplanned outages. Hydran and Kelman online gas analyzers monitor transformer condition by measuring gases dissolved in transformer oil and moisture, and report changes immediately to support operational monitoring.
Spatialworld delivers solutions for power transformer condition monitoring, including real-time monitoring and diagnostics of fault gases, as well as monitoring of other critical transformer components.
Why is transformer monitoring relevant now?
Predicting transformer failures is not just a technical issue — it is also about reliability, risk management, and maintenance prioritization. When fault gases, moisture, bushings, and on-load tap changers are continuously monitored, deviations are detected earlier and corrective actions can be taken at the right time.
The value of transformer monitoring is particularly evident when the goal is to improve reliability, reduce unplanned outages, support condition-based maintenance, and manage the lifecycle of critical transformers more systematically.
What does transformer monitoring cover in practice?
Transformer monitoring is not limited to a single measurement or device. With Spatialworld’s solutions, the monitoring setup can be tailored based on which components, phenomena, and operating environments are most relevant for the customer’s asset base.
1.
Online DGA and real-time monitoring of fault gases
Online DGA monitors gases dissolved in transformer oil and helps identify changes that may indicate emerging faults, loading conditions, or deterioration of transformer health. Real-time monitoring enables earlier response compared to analysis based only on individual oil samples.
2.
Transformer moisture monitoring
Moisture monitoring complements DGA and provides visibility into the condition of the insulation system. Continuous tracking of moisture changes enables decisions based on measured data rather than assumptions.
3.
Bushing monitoring
Bushing condition monitoring helps detect deviations in a critical component whose failure can pose significant operational risks. Therefore, online monitoring of bushings should be considered an integral part of comprehensive transformer monitoring, not a separate add-on.
4.
Monitoring of tap changers and cooling systems
Monitoring of the on-load tap changer (OLTC) and cooling system complements the overall picture when the goal is to detect deviations early and support data-driven maintenance prioritization.
5.
Partial discharge detection
Detection of partial discharges (PD) provides additional insight in situations where more detailed diagnostics are needed alongside DGA. This is especially important in critical environments where reliability has a major impact on production or grid operation.

How does the solution support practical operations?
The purpose of transformer monitoring is not just to collect measurement data, but to make it actionable for maintenance, operations, and decision-making. Alarm thresholds, trend analysis, and data interpretation help identify what requires immediate action and what can be managed over the longer term.
The solution can be integrated into the customer’s operational environment so that monitoring data supports control room operations, historical analysis, and asset risk management. Transformer monitoring is more than a measuring device — it is a tool for maintenance prioritization and risk-based decision-making.
For power grids, power generation, and heavy industry
Spatialworld’s transformer monitoring solutions are particularly suitable for power grids, power generation, power plant environments, and heavy industry, where the condition of critical transformers directly impacts reliability, safety, and production continuity.
Why Spatialworld?
Spatialworld combines a comprehensive range of transformer monitoring solutions, high-precision and high-quality products, and flexible local service. This is supported by GE Vernova’s expert network and a long standard warranty.
For customers, this means the solution does not remain a single device or isolated measurement. Instead, the goal is to build a functional, integrated system that fits the real operating environment and supports practical decision-making.
Frequently asked questions about transformer monitoring
Who is transformer monitoring especially relevant for?
Organizations with critical power transformers that need to improve reliability, reduce failure risks, and optimize maintenance timing. Typical environments include power grids, power generation, power plants, heavy industry, forest industry, and selected data center and infrastructure sites.
What does DGA (Dissolved Gas Analysis) measure?
DGA measures gases dissolved in transformer oil. The amounts, changes, and trends of these gases help identify deviations in transformer condition and support early fault detection.
Why use online DGA instead of laboratory oil samples?
Online DGA provides continuous real-time visibility into conditions and trends, supporting faster response than individual samples, which only reflect a single moment in time.
What else should be monitored besides DGA?
Depending on the need: moisture, bushings, tap changers, cooling systems, and partial discharges. The key is to build a solution that matches the criticality of the asset and its operating environment.
How is monitoring data utilized?
Data can be integrated into operational monitoring, historical data systems, and maintenance decision-making, ensuring it supports operations, prioritization, and risk management.
How does transformer monitoring support maintenance prioritization?
It provides early visibility into condition changes, trends, and alarm thresholds. When monitoring data is used in operations and maintenance decision-making, actions can be targeted to the right equipment at the right time.
