Delivery is made by truck whenever
possible or by rail when transformer
size or weight makes truck delivery
impractical. An impact recording
device is provided on all rail ship-
ments and can be provided on truck
shipments upon customer request.
Impact recorders measure and store
three-axis impact data, identifying any
abnormally severe impacts that might
have caused damage to the trans-
former during transportation.
Howard Industries offers a full
complement of field installation
services, including unloading, inspec-
tion, assembly, vacuum oil filling, and
testing under the supervision of field
service technicians (Figure 24). Field
supervision is available for customer-
installed jobs. Field inspection
includes checks of bushings, gasket
seals, tank pressure, tap changer
operation, and controls. Tests include
turns ratio, insulation resistance,
power factor, internal moisture, and
oil dielectric strength.
