FLD M Online Transformer Monitoring System
The FLD M system performs two functions (operates in two modes). The first function is remote online monitoring of critical transformer parameters. The second function is filtration and dehydration of transformer oil when its quality deteriorates. The second mode is activated automatically without operator's intervention; the transition from transformer oil filtration and dehydration back to transformer parameter monitoring also occurs automatically.

Description
The FLD M system performs two functions (operates in two modes). The first function is remote online monitoring of critical transformer parameters. The second function is filtration and dehydration of transformer oil when its quality deteriorates. The second mode is activated automatically without operator’s intervention; the transition from transformer oil filtration and dehydration back to transformer parameter monitoring also occurs automatically.
Monitoring is achieved by connecting the FLD M system to the transformer, where it remains installed nearby. The oil continuously circulates from the transformer through the system’s sensors and back into the transformer. Some parameters are measured with the use of sensors, while others are calculated by specialized algorithms. The measured and calculated transformer parameters are then transmitted and stored in a dedicated web application, where they can be accessed from anywhere in the world with an Internet connection.
The FLD M system enables detection and monitoring of the following transformer parameters:
- Oil temperature at the transformer top and bottom;
- active water in oil at the transformer top and bottom;
- ambient air temperature;
- relative humidity of ambient air;
- moisture content of oil at the transformer top and bottom;
- moisture content of solid insulation in the transformer;
- dielectric strength of oil;
- oil quality index;
- hydrogen content of oil (optional).
Each parameter at any given time falls within a specific color-coded range: “Within normal limits” “Outside the limits. Operator’s attention required,” and “Critical zone. Operator’s intervention in transformer operation required.” A predictive function for parameters is also available, allowing for advance planning of transformer maintenance and repair activities.

Advantages
The FLD M system offers the following key advantages: low relative cost, compact size, a service life comparable to that of the transformer, a user-friendly web application, easy connection, and more comprehensive information with improved assessment of transformer condition dynamics compared to laboratory analyses.

Application
The FLD M can be used to monitor all transformers filled with transformer oil, regardless of their purpose or application (power supply, power distribution, mining, traction, marine, wind farm, and other transformers).
