MAINTENANCE AND PERIODIC INSPECTION

In order to assure a long lifetime and correct and reliable operation of equipment delivered for this facility
it is of utmost importance to perform maintenance regularly.

Following general rules should always be considered before starting maintenance activity.

1.

Authority from responsible engineer 

shall always be obtained 

before 

starting any maintenance.

2. Follow 

safety procedure established

 in carrying out the work.

Realize  that no set of safety

 or maintenance instructions 

will ever be written that can adequately cover all

accident possibilities.

Therefore 

"SAFETY" 

as dictated by actual current conditions, always takes precedence over any

previously prepared safety or maintenance instructions. 

Assume nothing

Take the precautions that you

personally deem necessary in addition to those included in standard practice.

Be familiar with the drawings and previous test records before starting activity.

Scrutinize maintenance instructions given for the equipment to be maintained.

Maintenance information is given in the Operation and Maintenance Manual for each type of equipment.

The main dangers of such process are:

Inaccessible lubrication points (greased for life) cannot be lubricated and may seize up.

Areas not lubricated may be subject to corrosion.

The high-pressure spray may damage equipment.

Especially protective coatings may be removed.

Bolt Tightness

All  connections should be tight and secure. Bolts and nuts on busbar and terminal lugs should be
torqued and marked properly.

Inspection and Testing

The need for preventive maintenance will vary  on operating conditions. Where heavy dust conditions
exist, an accumulation of dust on the equipment may effect the operation of unit substation and its
protective apparatus.
When  normal maintenance inspection and cleaning of bus connections, relays, lug connections, and other
part of the distribution system is being made, it is  advisable  to  operate and check circuit breaker or
switch-disconnector operation. The following procedure is highly recommended.

Personal Caution is your best Safeguard

IMPORTANT

We draw your attention to the risk involved in using any cleaning process based on the
high pressure spraying solvent of an insulating solvent.
