MAINTENANCE
A periodic visual inspec on of the transformer is recommended. At
such mes, the general condi on of the following should be noted:
1.
High voltage bushings
2.
Low voltage bushings
3.
Arresters (if provided)
4.
Evidence of oil leakage
5. Ground
connec ons
6. Accessories
7. Safety
labels.
Where tanks show evidence of rus ng or deteriora on of the
fi
nish,
they may be cleaned and then retouched with paint. It is necessary to
remove all loose paint and rust by wire brushing, scraping, or sanding,
and clean with a good solvent. Apply an acrylic lacquer, alkyd enamel,
two part urethane or silicone alkyd primer, allow to dry, and then
apply a color matched compa ble top coat and allow to dry.
If metal is rusted to the point of being weak such that the tank
integrity can be compromised, repair or replace the part rather than
pain ng it.
