7 Commissioning

Test the correct operation of electronic sectionalizer on a regular basis, preferably while

maintenance on head recloser is made:

- Check the closing system.

- Check that the interlocking bolt turns freely. The tensioning device support should move

easily and the spring should be sufficiently tightened so that the support may reset when

the system opens following the operation of the sectionalizer.

- Check that the mobile lever and the lower support of the AutoLink move easily at the

joint. Clean and lubricate the joint surfaces of both pieces.

- Keep contact zones clean and place a thin film of conductive grease on those zones.

Test should be carried out on a laboratory with the appropriate equipment to simulate

service conditions. For this operation it is recommended to contact ABB for requesting

testing procedures.

All operations regarding commissioning must be carried out by suitably

qualified customer personnel with in-depth knowledge of the apparatus and

the installation itself.

Do not open the disconnecting switch under charge using a common pole, as

it could cause an arc that could damage the personnel or the equipment. The

disconnecting switch has horns to be used with a load break tool to carry out

this kind of operation.
