From production right through to the end consumer, electrical substations are at the heart of the energy distribution network.  Furthermore, with the trend towards Smart Grids, these substations are becoming increasingly complex as they evolve, day by day, to manage an ever growing number of functions

As strategically important locations, guaranteed availability of their control and protection systems is a must.  Even with power available upstream, if the control system should fail it would no longer be possible to manage power transmission.

In this document you’ll see how Transfer Switching Equipment can be used in order to increase availability of auxiliary power systems in this kind of application.
