transec - online transformer drying solution

TRANSEC is a system to dry Power Transformers of all sizes. The Problem of wet Transformer is already well known. Due to moisture and oxygen, the insulation paper within the Transformer degenerates. One of the products of this chemical process is H O. While only a small part 2 of the moisture is absorbed by the Transformer oil, more than 95% of the moisture becomes diffused in the tons of insulation paper. Depending on the percentage of moisture, the aging of the Transformer increases and failures such as flashovers between the windings, treeing, and creeping discharges occur. Temperature changes of the oil during the operation even increase the risk of an outage.

Once the oil in the Transformer gets dried by TRANSEC, it dehumidifies the insulation paper and returns back again to the unit. Using this cycle effect, TRANSEC keep the insulation paper permanently dry, ensure a faultless operation and elongates the life expectancy of the Transformer significantly. Comparing to other solutions, the Transformer can be dried during its operation. There is no need to transport or switch it off.

TRANSEC is an online drying sieves. The unit consists of an electrical pump, special water absorber cylinders and measuring sensors to monitor the amount of removed water. The System can either be mounted directly on a Power Transformer or can be installed next to it. Two pipes are connected to the upper and lower part of the Transformer body. After the unit is installed and switched on, the pump continuously cycles the transformer oil through the cylinders. Within the cylinders, water absorbing material removes the moisture from the oil. After this process, the oil goes through a particle filter to ensure its cleanliness before it returns back to the Transformer. An inbuilt deaerator insures, that no air will enter the tank. Every TRANSEC unit includes sample / measuring points at the inlet and outlet (to check the moisture content in the oil). An additional prefilter and a monitoring system can be added to the unit as an option.
