Abstract: There is provided a method of improving an electrical link box. The method includes steps of opening the electrical link box to provide access to a space within the electrical link box; inserting an electrical link box safety improving container into the space in the electrical link box; and closing the electrical link box; wherein the electrical link box safety improving container contains a filling material for mitigating blasts in the electrical link box. A safer electrical link box may be provided using the method.

Abstract: System for controlling voltage supply to a portion of a distribution grid, the portion of the grid including a substation providing one or more circuit element operable to increase or decrease the voltage supplied to consumers within the portion of the grid. Data set includes a previously measured power consumption associated with previously measured values of at least one property for a portion of the grid. Measurement device measures the at least one property supplied within the portion of the grid. Processing device determines from the previously measured values of the at least one property in the data set an effect of altering the value of the at least one property from a first value to a second value, on the power consumption of those consumers.

Abstract: A control system for and a method of fault isolation and electrical power restoration on an electrical network are provided and comprise: a plurality of electrical power supply facilities connectable to a region of a network, the region comprising a plurality of segments, and each segment being connectable to one or more neighbouring segments by a respective switching device; and the method including the steps of: detecting a fault condition within the region; operating the plurality of switching devices connecting the segments within the region so as to disconnect those segments from one another; performing a reconnection routine for each of a plurality of reconnection zones, being run concurrently.

Abstract: System for controlling power consumption on a portion of a distribution grid providing electrical power to a plurality of power-consuming units and including a substation providing one or more transformers operable to increase or decrease the voltage supplied to consumers within the portion of the grid. A data set includes a previously measured power consumption associated with previously measured values of (a) property(ies) being one of voltage, current, frequency or load, or a combination thereof. A measurement device for measuring the property(ies) of the grid. A processing device to determine from the previously measured values of the property(ies) a most likely effect of altering the value(s) of the property(ies) from a first value to a second value. A storage device for storing one or more rules associating a measured condition with a corrective action. The system being operable to determine whether a measurement meets a measured condition of a stored rule.

Abstract: System for controlling voltage supply to a portion of a distribution grid. The portion of the grid including a substation providing one or more transformers operable to increase or decrease the voltage supplied to consumers within the portion of the grid. The voltage control system includes: a data set including a previously measured power consumption associated with previously measured values of a property(ies) being one of voltage, current, frequency or load, or a combination thereof, a measuring device to measure the property(ies) within the portion of the grid, a processing device to determine a most likely effect of altering the value(s) of the property(ies) from a first value to a second value, a storage device for storing one or more rules associating a trigger event with a response action associated with the substation, and a control device to receive a measurement of the property(ies) within the portion of the grid.

Abstract: System for controlling voltage supply to a portion of a distribution grid. The portion of the grid includes a substation providing one or more transformers operable to increase or decrease the voltage supplied to consumers within the portion of the grid. The voltage control system providing a data set can include a previously measured power consumption associated with previously measured values of (a) property(ies) for a portion of the grid, the property(ies) being one of voltage, current, frequency or load, or a combination thereof. The voltage control system can provide a measurement device to measure the property(ies) supplied within the portion of the grid. The voltage control system can provide a processing device to determine from the previously measured values of the property(ies) in the data set a most likely effect of altering the value of the property(ies) from a first value to a second value, on the power consumption.
