2 Receiving

2. Receiving

2.1 Unpacking

Check that the packages are free from transport damage. Open the covers of the transport

boxes. Remove the supporting blocks of wood. If the package is damaged a careful investi-

gation must be carried out.

Lift the on-load tap-changer, using the lifting eyes on the top.

2.2 Inspection upon receiving

1. Check that the on-load tap-changer, drive shaft system, motor-drive mechanism and

accessories are undamaged.

2. If transport damage is found, and it is judged that correct operation of the on-load tap-

changer is not possible, a damage report should be sent to the insurance company. It is

also recommended that photos are taken of the damaged details. Mark the photos with

ABB’s reference number and the serial number of the on-load tap-changer and send

them to ABB for comments.

3. Check that the parts delivered, type designations and the serial number agree with the

delivery documents, e.g. the packing list or ABB’s ordering acknowledgement. The se-

rial number is stamped on the rating plate and on the on-load tap-changer ange, see

Fig. 3. The serial number on the parts belonging to one on-load tap-changer unit should

all be the same.

2.3 Temporary storage before assembly

If the on-load tap-changer is not to be assembled immediately, once the delivery has been

approved the on-load tap-changer and the motor-drive mechanism must be kept warm and

dry indoors. Let the units be kept in their plastic enclosures and leave the drying agent until

assembly.
