Abstract

A system of surge suppressor units is connected at multiple locations on a power transmission and distribution grid to provide grid level protection against various disturbances before such disturbances can reach or affect facility level equipment. The surge suppressor units effectively prevent major voltage and current spikes from impacting the grid. In addition, the surge suppressor units include various integration features which provide diagnostic and remote reporting capabilities required by most utility operations. As such, the surge suppressor units protect grid level components from major events such as natural geomagnetic disturbances (solar flares), extreme electrical events (lightning) and human-generated events (EMPs) and cascading failures on the power grid.

Claims15

Dependent claims

A surge suppression system of a power distribution system of a power grid which provides power to low-voltage power consumers, comprising:

at least one surge suppressor unit which is configured to connect, via respective direct electrical connections, in parallel to at least one of (i) a first set of power distribution lines on a primary side of a three phase system transformer of said power distribution system and (ii) a second set of power distribution lines on a secondary side of said system transformer, each surge suppressor unit configured to correct at least one of voltage imbalances and phase imbalances in respective phases carried by said power distribution system resulting from one or more disruptions caused by an external disturbance to said power distribution system from at least one of conduction associated with an electrical disturbance and induction associated with an electromagnetic disturbance through said first set of power distribution lines or said second set of power distribution lines;
wherein said primary and secondary sides transform a three phase power from a first voltage on said primary side to a second voltage on said secondary side different from said first voltage.

Dependencies are inferred from the claim text.
