Therefore, a power supply unit (power supply circuit) is used for the operation of electronic devices to convert AC to DC and regulate voltages. For example, an AC adapter is commonly used as a power supply device. Power supplies built into electronic equipment are also called AC/DC power supplies or switched-mode power supplies.
4 Substation Auxiliary Power Supplies 4.1 INTRODUCTION All but the smallest substations include auxiliary power supplies. AC power is required for substation building small power, lighting, heating and ventilation, some communications equipment, switchgear operating mechanisms, anticondensation heaters and motors.
In this case the DC supply is duplicated to each control and relay panel by sectionalizing the DC distribution board and having separate feeders to each panel. Each relay and/or control panel DC circuit associated with each power substation circuit is also monitored for loss of DC supply.
Capital cost and reliability objectives must first be considered before defining the battery and battery charger combination to be used for a specific installation. The choice for substation auxiliary supplies lies between lead acid and nickel cadmium cells and variants within these categories.
