Fault category and status code through ratio code [25].

Three-ratio code	Nonfault and fault	Status code
000	Nonfault	0
001	Low temperature overheating (below 150C)	1
020	Low temperature overheating (150C)	2
021	Medium temperature overheating (300C)	3
0 2	High temperature overheating (above 700C)	4
010	Partial discharge	5
10 11	Low energy discharge	6
12	Low energy discharge and overheating	7
20 21	Arc discharge	8
22	Arc discharge and overheating	9

0, 1, and 2 for simplicity.
