According to ANSI/NETA MTS, how often should a medium voltage switchgear with a high reliability requirement in good condition be electrically tested and maintained?
It says .75 which should be 9 month or ¾ of a year.
could you please post the part where it says switchgear should be tested every 12 months? thank you!
The regular maintenance interval for MV SWGR is 24 months.
0.75 x 24 = 18 (months).
