- Easy and safe installation and commissioning: 100% computer-controlled
- No disconnection of the transformer under treatment, not even during the installation of the dehydrator (Plug & Play design)
- No air venting after installation: hydraulical interconnections to a transformer oil filling are set under vacuum and subsequently rinsed by oil
- Moisture and particles content is reduced to the level of a new transformer
- Quick restoration of dielectric strength of oil
- No impact on the insulating oil properties and DGA
- Direct check of dehydration efficiency based on the amount of removed water: calculated as the product of difference input-output water content in oil (2 x humidity sensors) x precise volumetric reading of oil throughflow
- Easy and safely replacement of adsorbent cartridges and filters without a potential oil spill
- Remote monitoring & control of drying process
- Calculation of actual value of dielectric strength (Ud-value) of oil
- Easy verification of simulated Ud-values by lab reading(s) by means of Verification diagram
- DOG (Dynamic Overdrying Guard) procedure inhibits the overdrying of hard insulants
ADT ON-LINE DEHYDRATOR & ADT MINI ON-LINE DEHYDRATOR
S-03 ON-LINE DEHYDRATION AND FILTRATION OF TAP-CHANGERS
Designed for the continual operation for the filtration & drying of insulation oils in tap changers & load selectors of main transformers under normal operational conditions. diluted water, as well as mechanical particles, are bound into the large volumes filter insert during the operation
- The thermal stratification layer then effectively obstructs free mixing of hot oil from the main tank with the cold, and air and moisture contaminated, oil from the conservator
- Permanent low oxygen level in the oil induces the high-order decreases aging intensity of the oil-cellulose system of a transformer
- Easy and simple installation – no modification of the conservator ot the main tank of the transformer is necessary
- No maintenance – the sealing element as a natural phenomenon of the oil is indestructible
TRAFOSEAL
New art of sealing of power transformer utilizing a thermal stratification layer, which spontaneously arises as an “interface” between hot oil (main tank) & in cold oil (conservator) in the trafoseal tank
- The thermal stratification layer then effectively obstructs free mixing of hot oil from the main tank with the cold, and air and moisture contaminated, oil from the conservator
- Permanent low oxygen level in the oil induces the high-order decreases aging intensity of the oil-cellulose system of a transformer
- Easy and simple installation – no modification of the conservator ot the main tank of the transformer is necessary
- No maintenance – the sealing element as a natural phenomenon of the oil, is indestructible
SIMMS 2.2: IN SITU DIAGNOSTICS OF TRANSFORMER
- Easy and quick connection to the oil sampling points of a transformer
- Automatic tracking of Tx temperatures and water content in the oil
- Check of the temperature and water content equilibrium
- First data snapshot about a moisture and gas problem of a transformer already within 30 – 40 minutes
- Evaluation of water content in hard insulants
