Electrical Energy Storage: an introduction
Introduction. Electrical energy storage systems (EESS) for electrical installations are becoming more prevalent. EESS provide storage of electrical energy so that it can be used later. The approach is not new: EESS in the form of battery-backed uninterruptible power supplies (UPS) have been used for many years.

A Complete Guide of What is Earthing Switch
What is Earthing Switch Used for. Earthing switch is used to provide a ground line to an underground or delta-connected system. Earthing switch allows the connection of phase-to-phase loads. The earthing switch in substation is grounded to give a low-impedance link to the ground, which keeps the system neutral.

Introduction to energy storage
This is defined in Eq. (1), where the total energy transferred into ( Ein) or out of ( Eout) the system must equal to the change in total energy of the system (Δ Esystem) during a process. This indicates that energy cannot be created nor destroyed, it can only change forms. (1) E in − E out = Δ E system.
