What are the different modes in which Battery Charger operates ? A Battery Charger is an important element of auxiliary power systems (APS) , which supplies DC Supply to the Substation DC Loads and at the same time continuously charges the Substation Battery Set.
Power substation DC system consists of battery charger and battery. This is to verify the condition of battery and battery charger and commissioning of them. Following instruments will be used for testing: Multimeter. (Learn how to use it) Battery loading unit (Torkel-720 (Programma Make) or equivalent.
So in normal conditions, it is the charger that supplies DC power to protection, communication, control, and measurement devices running in the Electrical substation & not the battery bank. 3. D-C-D-B: DC Distribution Board
The primary role of the substation battery system is to provide a source of energy that is independent of the primary ac supply, so that in the event of the loss of the primary supply the substation control systems that require energy to operate can still do so safely.
