Common indicators of IEEE 1366-2012 and DL/T 836-2016.

Indicator type	Indicator name	Nonidentical part
System user index	Average supply reliability (ASAD)	IEEE1366-2012: Only continuous outages (outage time greater than 5 min) are considered
		DLT836-2016
		(1) Considering both continuous outage (outage time greater than 3 min) and short-time outage
		(2) Further refined into 4 indicators according to whether to take into account external influence, system power shortage limitation, and short-time power outage
	System average outage duration (SAID); System average outage frequency (SAIED)	IEEE1366-2012: Only continuous outages are considered
		DLT836-2016
		(1) Considering both continuous outage and short-time outage; (2) Further refined into 6 indicators according to whether to take into account external influence, system power shortage limitation, and short-time outage, as well as separate statistics for prearranged outage and fault outage
Outage user index	Average outage customer outage time (CAIDD); Average time per outage (CTADI); Average outage frequency for customers with power outages (CAIFD)	IEEE1366-2012: Only continuous outages are considered
		DLT836-2016
		(1) Considering both continuous outage and short-term outage
		(2) Further refined into 2 indicators according to whether short-time outages are taken into account
Long-time outage index	Ratio of customers with a prolonged power outage
	Ratio of single long-time outage customers
Repeat outage indicators	Ratio of customers with multiple outages; Ratio of customers with multiple persistent outages
Load-based metrics	Average system equivalent downtime (ASIDI)
	Average system equivalent outage frequency (ASIFI)
Short-term outage indicators	System average short-time outage frequency (MAIFI)	DLT836-2016: 2 additional indicators based on separate statistics for prearranged outages and fault outages
