The well being of transformers and its uninterrupted functioning is an inevitable necessity in the fast moving highly developed world filled with gadgets, electric and electronic items. The importance of a vacuum drying oven for transformer is felt when one understands the transformer’s role in ensuring safety and efficiency of power systems by adjusting voltages when required.

Vacuum drying oven for transformer and removal of moisture content

Moisture in the transformer refers to traces of water absorbed by the paper and present in few places like being dissolved in the oil, the solid insulation or as liquid water in the bottom of the transformer. As an initial step to confront the issue, the excessive moisture content in the transformer must be confirmed through water in oil analysis. If the moisture is not removed with the help of a vacuum drying oven for transformer, the chemical decomposition which occurs due to oxidation of the cellulose would minimize the lifespan of the transformer.

Necessity of vacuum drying oven for transformer

Employing a vacuum drying oven for transformer is unavoidable since situations may arise when the traces of water are found in active part of the equipment, the transformer is without oil for more than a year, self indicating silica gel loses its blue colour, the active part of transformer is exposed to exterior atmosphere and when the standard values of the transformer are not restored despite dehydration. Hering’s vacuum transformer drying oven is designed in a compact and efficient way to dry the transformer’s active parts. The transformer vacuum drying oven is both easy to operate and maintain.

Transformer drying oven and lifespan of the apparatus

Lifespan of transformers is secured by drying both the insulating oil and the insulating material. While extending the lifespan, automatically financial expenditures are reduced and this adds to the profits. A higher dielectric strength is obtained which is displayed in the performance of the transformers.

Functioning of Hering vacuum drying oven for transformer

The transformer vacuum drying oven is of two types based on the process used of which one is a hot air drying plant with an easy setup and another is vapour phase drying plant with reduced process duration.

Reducing pressure leads to low boiling point and enables vaporization of moisture content and this process comprises three steps including heating, evacuation of autoclave and cooling.

The air drying plant and phase drying plant models of Hering’s transformer drying oven differ from one another in the heating up phase with different magnitudes of heat transfer. As for the advantages, vapour phase model enables faster drying while the hot air model is easily installed.

Hering ensures that the drying plants, which are subdivided to modules, are pre tested in their workshops before reaching the client. This procedure ensures fast, easy and safe installation at the client end, thus ensuring Hering’s matchless German precision and professionalism which makes the brand march proudly beyond its century old expertise.
