Installation Standards for Relay Protectors
This handbook covers the code of practice in protection circuitry including standard lead and device numbers, mode of connections at terminal strips, colour codes in multicore cables, dos and donts in execution. Relay systems protect high-voltage equipment and transmission lines to ensure safe, stable systems. Although failure of a protective relay system may have severe local or regional impacts, most protective relay systems are not required to operate to prove they are in working order. Many of the protective relay systems are seldom called upon to work and have little means of proving they. This utility standard establishes the requirements for testing and maintaining protection systems, automatic reclosing, and sudden pressure relaying. Proficient in all ABB/GE medium and low voltage distribution products. All persons responsible for applying the equipment addressed in this manual must satisfy themselves that each intended application is suitable and acceptable, including that any applicable safety or other operat onal requirements are complied with.
