OIL FILLED CUTOUT
OIL FILLED CUTOUT
(OP)
Hello,
I am looking for some direction on OIL FILLED CUTOUTS and a maintance plan.
SPECS: 4kV, 100 & 200 Amp, Oil Filled, Submersible.
Basically, I am trying to develop an inspection program for the OFCO in effort to determine when it should be replaced.
I am looking for some criteria on how to evaluate an OFCO and if other utilities have a OFCO replacement plan.
If so, how do you "track" the OFCO and determine to replace it or not?
thanks!

Some of the oldest are in perfect condition - the environment the OFCO is in and elements which it is exposed to determine the condition of the unit.
I agree the OFCO's are prone to violent failure - however [if] maintained can provide an effective solution to 4kV switching and isolation.
My biggest concern is that by moving towards the vacuum based cutout (G&W) requires many of my manholes to be enlarged - very expensive.
We have been refurbishing the units (sandblasting, repainting, and oil replacement) - but we do not have a good way to test the unit in an effort to determine if an energized unit is unsatisfactory for operation.
The "VISUAL" inspection method - what we use now - has caused us to replace many OFCO's that have are satisfactory for operation - upon further investigation, we found the oil to be in good condition.
thanks!
