Physical Inspection (cont.) Components
Check all components for any signs of damage or overheating. Any
components displaying physical damage or severe discoloration should be
replaced (see Chapter 8). In particular, check the capacitors for ruptures and
make sure there is no leaking dielectric fluid.
Interlocks
Check for proper functioning of all door interlocks (clip type and key type).
They must prevent medium voltage doors from being opened if there is power
applied to the filter.
Foreign Material
Check for dust, dirt, iron filings etc. that may have entered the structure and
vacuum clean if necessary. In particular, check the cooling fans and vents to
make sure they are unobstructed.
