The FLD 0.15D system is designed for the online drying of transformer insulation (oil and paper insulation).
The system’s operating principle is based on the fact that in a loaded, operating transformer, moisture migrates between the paper insulation and the oil. Therefore, the FLD 0.15D online dry-out system is connected to the transformer and remains near it throughout the drying period. The transformer oil is circulated through three sorbent cartridges in the FLD 0.15D online dry-out system. Due to its high absorption capacity, the sorbent extracts moisture from the oil, after which the dried oil is returned to the transformer.
As a result, prolonged drying not only reduces the moisture content in the oil but also in the transformer’s paper insulation. If needed, the FLD 0.15D online dry-out system can be additionally equipped with a special protective enclosure.
