INTRODUCTION
1.1 These instructions apply to Substation transformers
manufactured by the Westinghouse Small Power Trans·
former Division at South Boston, Virginia.

transformers can be dangerous, and failure to follow these
instructions can cause danger to life and damage to prop
erty.
1.2 The equipment covered by these instructions should
be operated and serviced only by competent personnel
familiar with good safety practices. These instructions are
written for such personnel and are not intended as a sub
stitute for adequate training and experience in the use of
this equipment.

1.4 Substation transformers are designed according to the
latest revision of ANSI Standards C57.12.00 and C57. 12.10
in effect at the time of design. A typical Substation trans
former is shown on the cover of this Instruction Book.
Electrical characteristics, winding connections and weights
are on the nameplate. Refer to the outline drawing for the
physical details. Fan, control and alarm wiring are on the
wiring diagram called for on the outline drawing. Trans
former operation is described in Sections 7. 1 and 7.2 of
this book.
1.5 The instructions in this book are adequate to handle,

RECEIVING
NOTE:
INSPECTION OF TRANSFORMER, PACK·
AGES AND PARTS IS REQUIRED PRIOR TO UN
WADING FROM CARRIER, IN ORDER TO
EST AB·
LISH THE CONDITION OF THE EQUIPMENT UPON
DELIVERY.
2.1
Drawings and Documents
Shipping papers, packing lists, outline drawings, instruc
tion leaflets and other pertinent documents furnished
with the transformer must be available for use during the
inspection.
2.2 External Inspection
All transformers are carefully tested at the factory and are
in good condition when shipment is made. However, upon
receipt inspect the transformer, inspect packages and
parts for possible shipping damage. Also, check the bill
of lading for possible shortages. If the inspection indi
cates a shortage, damage or evidence of hidden damage, it
must be reported to the carrier's representative and to a
Westinghouse representative before unloading the trans
former. The external inspection should include all, but is
not limited to, the items in the "CHECK LIST". When a
"CHECK LIST" question is answered as shown, it should
be reported as damaged.
2.3
Tank Pressure
The
tank
pressure may be positive or negative when re
ceived, depending on liquid temperature. In some cases,
the vacuum pressure gauge may read zero, which could
indicate a tank leak. In such cases, pressure test the tank
according to the instructions in Section 6.6, Paragraph l.
Report tank leaks of new transformers to the local West
inghouse Sales Office.
2.4 Detail Parts
All detail parts should be checked against the packing list
to make certain that there are no shortages. The crates
and boxes should be carefully examined for evidence of
damage.
In making examinations of any parts or crates for ship·
ping damage, check carefully for evidence of moisture
