Online Transformer Monitoring
DC-5M Online Transformer Monitoring System
The DC-5M system is designed for online transformer monitoring by evaluating the condition of insulating oil in special-purpose equipment such as traction, mining, electric furnace, marine, and wind turbine step-up transformers. The DC-5M system, including the DC-260D and DC-260DH versions, can operate in transformer drying mode and transformer insulation monitoring mode. The system is connected to the transformer and constantly located nearby. Upon connecting the system, a closed circulation loop is formed: the oil comes from the transformer tank bottom, passes through the DC-5M system sensors, and returns to the transformer top. The sensors measure transformer oil parameters once a minute and transmit them to a cloud server, where other parameters are calculated using the DRYCORE technique to ensure a more comprehensive evaluation of transformer condition.

Key transformer parameters monitored by DC-5M system:
- Moisture content of oil at the transformer top and bottom;
- moisture content of solid insulation at the transformer top and bottom;
- dielectric strength of oil;
- oil quality index.
In order to view all the measured and calculated parameters from anywhere in the world, all you need is an Internet connection to access the password-protected web page. There you can find information about all the transformers connected to DC-5M systems.
You can view the data for any period of time. The information is conveniently presented in the form of graphs, dot charts, and labels, while transformers are clearly displayed on the world map.

Benefits
Key Benefits of the DC-5M
- Capable of Working with Transformers of any type: compatible with transformers of any design, rating, and age.
- Fast Connection: connection to the transformer takes approximately one hour.
- Energy Efficiency: operates without oil heating, which reduces energy consumption and thermal stress.
- Fixed or Temporary Installation: can be installed permanently or temporarily depending on operational needs.
- Quick Adsorber Replacement: adsorbers can be quickly replaced, which minimizes equipment downtime.
- Regeneration-ready Adsorbers: adsorbers are designed for repeated sorbent regeneration cycles.
- Protective Housing: the system is securely enclosed in a housing for protection against environmental and mechanical exposures.
- Remote Monitoring: transformer parameters can be monitored remotely via the Internet.
- Maintenance Planning: enables planning and optimization of transformer maintenance programs.
- Cost Savings: reduces expenses for laboratory oil analyses and transformer maintenance.
- Extended Transformer Service Life: continuous monitoring of transformer condition helps extend transformer lifespan.
