TDS ONLINE DRYOUT SYSTEM FOR OEM’S

TDS ONLINE DRYOUT SYSTEM FOR OEM’S

Technology

Technology is of Online Dryout process for drying out wet transformer in energized conditions by monitoring the percentage of Moisture in the insulation to its Dry Weight. PTss-Velcon TDS equipment is fitted with TIMES (Transformer Insulation Moisture Estimation System which automatically estimates the %M/DWi (%Moisture to Dry Weight of insulation) and triggers itself for self removal of moisture in Transformers. It uses Specialized cartridges for maintaining the %M/DWi to acceptable levels. This equipment is capable of being safely operated on transformers/reactors under energized conditions and is capable of being installed upto 764 KV Class. Process will not deteriorate any of the Oil characteristics before and after the process.

Process

PTss-TDS is basically designed to operate on an energized Transformer to remove moisture from it. The moisture is removed by circulation of Oil through TDS which has special type of absorptive cartridges which absorb and remove moisture from the oil. This process does not employ any heating or vacuum process of oil thereby retaining the original virgin characteristics of the oil. Process does not remove Oxidation inhibitors or fault gases. Equipment estimates the %M/Dwi (Percentage of Moisture to Dry Wt of Insulation) and automatically triggers itself for operation and is safe for unattended operation.
