Spot Networks – Low voltage lines typically serving one large customer or high-rise building in one or a few city blocks.

Faults (Radial or Network) – Equipment failures or conditions that must be interrupted to limit equipment damage, minimize the number of customers interrupted and eliminate potential safety hazards to workers and public.

Network Protectors – Devices that interrupt power when flows are from the secondary grid into the high voltage distribution system.  The protectors are usually attached to the low voltage side of the network transformer.

Circuit Breakers – Devices that interrupt power flows on a primary line, usually to isolate and clear faults.  Normally located in the substation, although many utilities install reclosers on lines to limit outage exposure.

Reverse Power Flow – When power flows from the low voltage side (secondary) into the high side (primary) of the network transformer, thereby causing network protectors to operate.

We have developed some key terms & definitions that should help us in addressing network interconnection (continued).
