Page 99 Some capacitor blowholes cannot be viewed directly until removed, or almost removed, from the rectifier. A dental-type mirror aids in viewing these capacitors' blowholes before disassembly. Lucent Technologies recommends that all dc capacitors in a rectifier be replaced whenever any one of them blows.
Page 100 ® Lucent Technologies Lineage 2000 100A Ferroresonant Rectifier J85503A-1 • All removal and replacement procedures are easier to perform on bay-mounted rectifiers that have been removed from the bay. • Most component removals are straightforward and obvious. Therefore, these procedures can be used as a guide by qualified service personnel, rather than as step-by-step procedures.
