Classification of grid construction standards.

Grid standard	Supply area classification	Load/MW	Recommended typical wiring patterns	Reliability rate target (RS-3)
T1	General areas (A+, A and B cores)	32,16–48	Double ring network, “N-1”	≥99.999%
	Channel tight (A+, A and B cores)	24,16–24	Two for one spare, three for one spare	≥99.999%
	High-capacity user-intensive (A+, A, and B cores)	32,8–48	Double direct supply opening and closing	≥99.999%
T2	Class B non-core	32,16–48	Segment moderate contact, “N-1”	≥99.965%
T3	Class C and below	As the case may be	Multisegment moderate contact, “N-1,” single radiation	≥99.897% (class C)
				≥99.828% (class D)
T4	Unable to oil pot due to user influence	As the case may be	As the case may be	Depends on user needs
