... consequent reduction of starting current. The starting torque is also reduced to one-third of that which would obtain with d.o.l. starting. With a single-cage or double-cage rotor of average performance, this represent about 80% of full-load torque, assuming normal line voltage, but if there is appr ...

... disruptive when the RMS magnitude drops lower than 90% of the nominal voltage [2]. Voltage sags are usually associated with system faults but can also be caused by switching of heavy loads or starting of large motors. Figure 1 shows typical voltage sag that can be associated with a single line-to gr ...

Benefits of voltage measurements with smart meters

... Some DSO personnel have been afraid that such large scale voltage quality measurements will cause very large amounts of data and will be both costly and difficult to operate. This does not have to be true! There are several ways to compress/reduce the amount of data. An example of an easy method is ...

Voltage optimisation

Voltage optimisation is a term given to the systematic controlled reduction in the voltages received by an energy consumer to reduce energy use, power demand and reactive power demand. While some voltage 'optimisation' devices have a fixed voltage adjustment, others electronically regulate the voltage automatically.Voltage optimisation systems are typically installed in series with the mains electrical supply to a building, allowing all its electrical equipment to benefit from an optimised supply.
