The self-checking facilities of numerical relays assist in minimising failures due to faulty relays. Defects in secondary wiring and incorrect connections are virtually eliminated if proper commissioning after scheme installation/alteration is carried out. The possibility of incorrect settings is minimised by regular reviews of relay settings. Network fault levels change over time and hence setting calculations may need to be revised. Switching and testing errors are minimised by adequate training of personnel, use of proven software, and well- designed systematic working procedures. All of these can be said to be within the control of the user.

The remaining three causes switching errors, application shortcomings, pilot wire faults etc. are not controllable, while two of these three are unavoidable – engineering is not science and there will always be situations that a protection relay cannot reasonably be expected to cover at an affordable cost.

Although protection equipment should be in condition when first put into service, problems develop unchecked and not revealed because of infrequent operation. With digital and numerical relays the in-built self-testing routines can be expected to reveal and annunciate most faults, but this does not cover any other components that, together, comprise protection scheme. Regular inspection and testing of protection scheme is therefore required. It is desirable to carry out maintenance on protection equipment at times when the associated power apparatus is out of service. This is facilitated by co-operation between the maintenance staff concerned and the network operations control centre.
