'정보블랙박스'’ of traditional transformers is being broken
In traditional power systems, 변압기 have long played the role of “자동 장치” – as long as they do not trip or emit smoke, they are assumed to operate safely. 하지만, with the increasing proportion of new energy grid connection, intensified load fluctuations, and increased complexity of distribution systems, this “post maintenance, experience based operation and maintenance” model is exposing huge risks.
이러한 맥락에서, the integration of 스마트 트랜스포머 and Internet of Things (IoT) technology is fundamentally changing the operation, 유지, and management of transformers, upgrading them from passive devices to intelligent nodes that are perceptible, analyzable, and decidable.

1.What is an Smart Transformer? Not just ‘adding sensors’
스마트 트랜스포머 are not simply installing thermometers or meters on traditional transformers, but rather a system engineering that integrates the sensing layer, communication layer, platform layer, and application layer. The core goal is to achieve digital management of the transformer’s full state, full cycle, and full scenario.
Its typical features include:
- Multi parameter online monitoring: temperature, 짐, 현재의, voltage, gas in oil, 부분방전, 진동, 습기, 등
- Edge computing capability: perform preliminary data analysis locally to reduce communication burden
- Remote communication capability: through 4G/5G, NB IoT, Ethernet or fiber optic access systems
- Data platform linkage: seamless integration with SCADA, EMS, DMS or cloud platforms
This has transformed the transformer from a ‘device’ to a data source and decision-making node in the power grid.
2.Core application scenarios of IoT in transformers
2.1 Real time monitoring of operating status
By deploying temperature sensors, 현재 변압기, and voltage acquisition modules, the system can real-time monitor:
- Temperature rise change of winding
- Load rate and overload trend
- Three phase imbalance situation
These data provide a quantitative basis for determining whether the transformer is in the “healthy operating range”.
2.2 Hotspot and Insulation Risk Warning
In oil immersed transformers, the hot spot temperature is highly correlated with the aging of oil paper insulation.
IoT systems can be combined with:
- oil temperature
- ambient temperature
- load curve
By calculating the hot spot temperature of the winding through the model, the risk of insulation aging can be alerted in advance to avoid sudden failures.
2.3 Partial discharge and early defect identification
With the help of ultrasound, UHF, or high-frequency current sensing technology, IoT systems can continuously monitor partial discharge signals and early identify the following issues:
- Insulation crack
- Moisture intrusion
- structure looseness
Such defects are often difficult to detect in traditional inspections, but they are the source of major accidents.

3.The value enhancement of Smart Transformers to the power grid system
3.1 Moving from “Regular Maintenance” 에게 “Condition Maintenance”
Traditional mode:
Annual or monthly maintenance, but without knowing the true condition of the equipment
Intelligent mode:
Determine whether maintenance is required based on real-time data
결과는:
The frequency of maintenance has decreased
Improve the utilization rate of operation and maintenance resources
Significant reduction in labor costs
3.2 Improving Power Supply Reliability and System Resilience
Through early warning and risk classification, transformer failures are no longer a “sudden event”, but a predictable and manageable process, particularly critical for industrial users, 데이터 센터, and new energy power stations.
3.3 Provide underlying data for digital grids and virtual power plants
The data generated by Smart Transformers can further support:
- load forecasting
- Distributed energy dispatch
- Digital twin modeling of power grid
4.Future oriented: Smart Transformers are the infrastructure of the “new power system”
Under the global trend of promoting carbon neutrality and digitalization of power systems, transformers are upgrading from “power equipment” 에게 “energy information nodes”.
Whoever holds the data holds the initiative in the system.
For manufacturers, this is an opportunity for product upgrades;
For the power grid and property owners, this is the key path to reducing the full lifecycle cost.
