3.1 Note the sensor ID number
Before installation, note the sensor´s ID-number together with the
respective arrester station, position, phase and type. The data is used
in the EXCOUNT-II software for correct registration. See section 2.7.
3.2 Common installation alternatives
The following are the most common installation alternatives, and
are included here for information only. The separate installation
instruction supplied with the actual delivery shall always take
precedence.
Alternative 1 (Section 3.4):
The sensor is mounted directly on the vertical upright surge arres-
ter base. This is the best alternative for charging the internal power
source and for complete measurement.
Alternative 2 (Section 3.5):
The sensor is mounted vertically on a planar surface. The sensor is too
far away from the surge arrester field, so the only possiblity to charge
the internal power source is via the solar cells (or separate DC battery).
NOTE! Resistive current measurement is not supported with alternative 2.
Alternative 3 (Section 3.6):
The sensor is mounted on a Transmission Line Arrester (TLA), for
example PEXLINK. Special consideration must be paid to the arrang-
ement, and a separate antenna (available as an option) may be necessary
for certain configurations (tall towers, for example).
Alternative 4 (Section 3.7):
The sensor is mounted directly on the inverted (under-hung) surge
arrester base. Special attention must be paid to the arrangement,
especially if resistive current measurements are to be made.
A separate antenna (available as an option) may be necessary for
certain configurations (tall gantries, for example).
3.3 Reference measurement
After completion of installation of the sensor and energization of
the surge arrester, a full set of measurements shall be made for
reference and then transfered to the PC software as described in
section 5 of this manual. Revert to ABB if any error codes occur
during measurement or transfer.
