Kit for on-site screening of PCB in oil

Friday March 17th, 2017
The SM-TCPs kit (Sea Marconi Total Chlorine and PCB screening) allows one to manage the life cycle of all electrical equipment filled with oil containing PCBs and their related control, inventory, decontamination and/or disposal tasks, in accordance with:
  • the European Council Directives (96/59/EC – Best Available Techniques, 96/61/EC – Best Environmental Practices 2001/68/EC), with
  • the Stockholm Convention on POPs
  • and other standards (IEC 60422 Ed.4-2013, CENELEC CLC/TR 50503 in February 2010, CIGRE 413 in April 2010).

The SM-TCPs kit allows you to determine PCB contamination of mineral insulating oils on site

The SM-TCPs kit (Patented method) can be used for the following reasons:

  1. environmental, in cases where there is no sign of PCB oil contamination in transformers and other electrical equipment (or in tanks)
  2. regulations, to verify compliance with the legislative limits
  3. functional, to evaluate, prevent or mitigate the risk of contamination during operations such as changing the oil, topping, depolarization, or maintenance work performed throughout the equipment’s life cycle.

The SM-TCPs kit can also be used on site since it does not require standard laboratory services.The test can also be done by normal staff members, thanks to the illustrated manual, tutorials and videos as well as Sea Marconi’s training and assistance service.

Due to global demand Sea Marconi has developed two versions of this kit: the POTENTIOMETRIC, and the COLORIMETRIC. Below are the main differences:

The SM-TCPs Kit was used in 2015 for the inventory of PCB contamination in Brazil promoted by the Brazilian Ministry of the Environment on a UNDP tender

If the results find that equivalent PCB level to be below the legal limit, the oil and the transformer can be classified as “NON PCB(green code). If the level is above the legal limit, the oil and the relative transformer can be classified as “suspect PCB(yellow code).
In Europe a concentration of PCB greater than 50 mg/kg is considered “suspect PCB“; if it is greater than 500 mg kg-1 then it is regarded as “Highly suspect PCB” (red code). In these cases the concentration value must be confirmed by an accredited laboratory using official methods (CONTACT FOR MORE INFORMATION).
Disclosure to the relevant authorities about the contamination of electrical equipment must be carried out, in any case, by an accredited laboratory using chemical analysis in accordance with the relevant regulation IEC-EN 61619 (PCB) EN-12766 (PCT and PCBT) .The laboratory certificates must report the methods used, the uncertainty and the laboratory competence requirements (EN ISO/IEC 17025, EN ISO 9001).
