A general rule of thumb would be to visually inspect every one to two years, secondary injection testing every one to three years, and primary injection every three to five years or on major changes. During visual inspection, the relay should be checked for any signs of damage, such as physical wear and tear, loose connections, or corrosion. The. Installation tests are field tests to determine that the protection operates correctly in actual service. Testing also needs to be done after installation, setting adjustments, or on any faults. 2 For a given protection scheme, all protection system components (protective relay, communications system, voltage- and current-sensing devices, and control circuitry) are tested at the same maintenance interval, as listed in Attachment 2, “Protection Scheme Types and Trigger Intervals,” Table. Purpose: To document and implement programs for the maintenance of all Protection Systems, Automatic Reclosing, and Sudden Pressure Relaying affecting the reliability of the Bulk Electric System (BES) so that they are kept in working order.
