PCBs Training workshop in Tirana
January 21st – 24th , 2014
PCBs sound management chapter B part 1
Life cycle management
Project approach
& Transformers as the main task to
combat PCBs cross contamination
Life time cycle of PCBs transformer
LIFE CYCLE OF TRANSFORMERS
The life time of transformers depends: -intention of use -location [open air or in a building] -aggressive air environment corrosion -manufacturing standards [special coating, oil extension tank, buchholz ..]
Life time of transformer
Life time of oil transformers -between 15 to 25 years ( transmission transformers ) -over 25 years (power transformers)
Life time cycle of PCBs transformer
Life time of PCBs transformer -because of excellent dielectric properties of PCBs & -chemical resistance again temperature elevations, non solubility in to water .. ~40 years
Life time cycle of PCBs transformer
During the life time of 40 years on a PCBs transformer may required: -to replace the dielectric oil or - to add in the PCBs oil mineral oil or -to empty the PCBs oil for maintenance
Life time cycle of PCBs transformer
Reason for PCBs cross contamination - emptying PCBs for repair -using the same pumps and -hoses or the -same oil storage tank -toping oil (add oil) Consider that a PCBs Maintenance FACILITY as “hospital of transformers”
Life time cycle of PCBs transformer Cross contamination
How and when occurs PCBs cross contamination?
If for each maintenance work
doesn't’ be checked the dielectric oil before!!
PCBs Cross contamination
Measures to combat cross contamination ?
Oil treatment and transformers maintenance facilities
should develop a system to control cross
contamination
Maintenance facilities of transformers
Methodology to Control cross contamination?? -Introduce at least: oil test before entering the facility -Analysis should be accurate and quick - If concentration PCBs >50ppm, store the oil in a separate second tank - classified transformer as PCBs should be managed according local legislation as hazardous waste
MAITENANCE OF TRANSFORMERS CROSS CONTAMINATION
PCBs producers/owners are asking ! How to manage a PCBs transformer /capacitor ? I have to take a decision for replacing or keeping!!
LIFE CYCLE management of transformer
PCBs Owners-Producers are faced on parameters as: -phase out date of 2025 -evaluate the remaining life time -cost benefit analysis between replacing or decontamination - evaluate the risk arising form the operation of a PCBs transformer (hospital, water sources, forest, school, etc .)
LIFE CYCLE management of transformer
1st Parameter PCBs phase out date of 2025 Albania governmental commitment against Stockholm convention -Signed 05-12-2001 -Ratified 4-10-2004
LIFE CYCLE management of transformer
2nd Parameter Evaluation of the remaining life time of transformer considering: -the external condition of transformer [corrosion level, leakages, damages ] -the internal- electrical condition of transformer , [ core , switches, poles/ insulators..]
LIFE CYCLE management of transformer
3rd Parameter Cost benefit analysis between replacing or decontamination considering: -costs to dispose all PCB -cost to buy new transformer or to decontaminate
LIFE CYCLE management of transformer
4th Parameter -Evaluate all risk arising from the operation of PCBs transformer. -neighboring activities -location of transformer [school, hospital, Power plant..] -water sources distance [River, lake distances ..]
LIFE CYCLE management of transformer
5th Parameter (continued) -Risk arising from the operation of PCBs transformer. -explosion [rise temperature, thunderbolt hit.. ] -leakage of PCBs [may contaminate water sources, soil.. ]
