equipment is required.
3. Protection elements setpoints verification (analog values injection or visual verification of setting file entries against
relay settings schedule).
4. Contact inputs and outputs verification. This test can be conducted by direct change of state forcing or as part of the
system functional testing.
5. Visual inspection for any damage, corrosion or dust.
