Given the importance of the protection relays in the operation of any equipment, a periodical test program is

recommended.

The interval between periodical tests varies normally for different types of relays, types of equipment as well

as the users' experience on periodical tests.

For systems which are not provided with testing equipment, it is recommended that the points described in

CALIBRATION AND RECEIVING TESTS be checked every 1 or 2 years.

The optional equipment described in previous sections, allows for checking on the correct operation of the

measure and alarm units and of the output elements, without having to remove the protection. In systems

provided with testing equipment, this check can be carried out in short intervals, and does not require

specialised personnel. In this case the frequency of the tests described in RECEIVING AND EQUIPMENT

CALIBRATION can be reduced
