Note that testing can be done by the manufacturer of an individual component, by an external
test house, or by the supplier of the complete system, or any combination of them as
appropriate. Where parts of the testing are carried out by persons or organizations other than
the supplier then the supplier shall keep copies of all test records and results supplied to them to
verify that the testing has been carried out by people with sufficient technical competency to
carry out the tests.

Note. For frequency Trip tests the Frequency requird to trip is the setting ±0.1Hz. In order to
measure the time delay a larger deviation than the minimum required to operate the protection
can be used. The “No-trip tests” need to be carried out at the setting ±0.2Hz and for the relevant
times as shown in the table above to ensure that the protection will not trip in error.
