Transformer Online Dryout System
Transformer online dryout system for online removal of moisture and solid contaminants from transformer oil
Transformer Online Dry Out System, is the ultimate low maintenance, low cost moisture management solution for the life of the transformer. Installed either on new transformers or those already in service, the Dryout System is designed for use on energised power transformers of all sizes, and will provide transformer owners with an economical, simple to operate, and low maintenance approach to maintaining water, acidity and particulate to very low levels in for the life of the transformer.
The Dryout System continuously removes water and particulate from the transformer oil and insulation on energized transformers of all sizes, and can be installed on either new or existing transformers. Because it can be permanently or temporarily (as per the requirement) installed on the transformer, the Online Drying Unit will maintain moisture at very levels for the life of the transformer.
Additionally, the Dryout system has the added capability of removing both moisture and acidity by simply changing the type of filter media used in the POD cylinders.
Installation of the Dryout System can usually be completed in a short amount of time. Oil supply to the Dryout System is taken from the bottom drain valve or low down in the cooling circuit. Oil from the coldest part of the transformer is preferred for maximum water removal.
Oil from the Dryout System to the transformer is normally to the bottom of the conservator, top of the main tank or any valve some distance away from the inlet supply valve.
Oil is circulated through the Dryout System and water is removed from the oil and stored in large capacity molecular sieve filter cylinders. The level of saturation of the filter media can easily be determined by comparing the incoming water in oil levels with the outgoing levels.
Dryout Systems can provide detailed advice on the optimal time to change the adsorbent media.
The Dryout Systems provides the transformer owner with a low cost, long term solution for managing moisture levels for the life of the transformer.
The cartridges can easily be replaced at customer point only.
This machine is capable to remove solid contamination and maintains NAS-4 and also monitors PPM level continuously.
It will keep maintaining PPM & NAS value which is required for long life and good health of transformers.
