Reliability
The earthing transformer which, as tests show, leaves the
factory free of defects, is prepared to provide service for its
entire «service life».
However, it is essential that the level of reliability be
maintained during its handling, storage, and transport, and
that it be put into service with the appropriate verifications
and protections established in medium voltage
electrotechnical regulations, and that its maintenance follows
the instructions compiled in these general instructions
document.
Additionally, it is necessary that required measures be taken
during its installation for the protection of those who work
around it, either regularly or incidentally, and that all external
personnel avoid proximity to it during its operation.
