TDM-10S / TDM-35S – Monitoring Systems for Power Transformers of up to 35 kV with Solid Insulation
The TDM-10S monitoring system is designed for the power transformers of up to 15 kV with cast epoxy winding insulation monitoring. The TDM-10S system uses several complementary diagnostic methods, for each of them specialized sensors are used:
- Winding insulation condition monitoring by discharge activity monitoring in the defect zones
- Transformer temperature monitoring and analyses
- Transformer load on-line monitoring
- Ambient temperature and humidity monitoring
- Transformer vibration monitoring
The TDM-35S monitoring system is designed for condition monitoring and operation management of power transformers of up to 35 kV with cast epoxy winding insulation.
Compared to the TDM-10S monitoring system, this system is more efficient due to the use of additional sensors and a more advanced expert system for assessing the transformer condition and diagnosing transformer defects.

Monitoring Systems for Oil-Filled Power Transformers of up to 35 kV
The TDM-10 monitoring system is for operational monitoring and diagnostics of oil-filled power transformers with an operating voltage of up to 15 kV. It monitors the transformer condition, and helps to estimate its residual life.
The TDM-10 monitors 6 main parameters of the power transformer:
- Oil temperature in the transformer tank – helps to determine the transformer load capacity and to calculate the insulation remaining life.
- Moisture content in the tank oil – determines the oil’s dielectric strength and its ability to operate at low temperatures.
- The oil level in the tank - a parameter of operational protection.
- Discharge activity inside the tank – the sign of the transformer insulation defects.
- Vibration in the transformer tank – characterizes the condition of transformer mechanical structure.
- Pressure inside the transformer tank.
The TDM-35 monitoring system is for operational monitoring and diagnostics of oil-filled power transformers with an operating voltage of up to 35 kV. Compared to the TDM-10 monitoring system, this system is more efficient due to the use of additional sensors and a more advanced expert system for assessing the transformer condition and diagnosing transformer defects.
