Method for detoxifying PCB-containing insulating oil in transformers etc.PROBLEM TO BE SOLVED: To correct the unreality of the conventional measure to carry out the whole cleaning step starting from breaking/crushing of a transformer, etc., inside a supercritical fluid circulating route for preventing...
doi:10.1080/10934528209375030The extent of PCB contamination in a large electrical utility distribution transformer system was investigated by obtaining and analyzing transformer oil samples from 260 transformers. Results indicate that 3.3% of the transformers in the distribution system contain PCBs at ...
The HERING PCB-RS PCB Removal System not only completely eradicates the PCB contamination from transformer oil, but also fully restores the contaminated oil to a good as new state.
