Motors direct-on-line

Starting large induction motors direct-on-line. 

Cables carrying surge currents, e.g. starting large motors direct-on-line. 

In a multi-machine network the generators and motors should be considered in relation to the source impedance to which they are connected. This impedance will also be dependent upon the location and type of disturbance e.g. near to a generator, remote from a generator, three-phase fault, line-to-ground fault, change in the state of the load such as starting a large motor direct-on-line.
