7 Commissioning
7.1 General procedures
8 Maintenance
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.
