Which type of battery are used in substation?
Lead Acid batteries
In industrial or substation applications mainly three types of batteries are used namely: Vented / Flooded Lead Acid batteries. Sealed maintenance free batteries/Valve Regulated Lead Acid. Nickel Cadmium (Ni-cd) batteries.
What is batteries in substation?
A battery is a primary component of a substation or switchyard DC control system. The function of the control system is to supply control power to operate critical devices such as protective relays, alarms and status indicators, supervisory and communications equipment, and switchgear operating circuits.
What are substation batteries used for?
Abstract: Nowadays, most transmission and distribution substations are equipped with batteries. These batteries are used as an emergency power supply for critical loads and therefore play a crucial role in substation availability.
Why DC batteries are used in substation?
The main reason for using DC supply in substation or power stations is to provide a continuous power supply to the control circuit. Only a battery can give continuous power supply until it fully discharges. The battery has electrical energy storing capability that’s why it can be used for backup power supply.
Which transformer is used in 33 11kV substation?
To step down the 33kV primary voltage to 11kV suitable for distribution purpose. One 33kV/0.415 auxiliary transformer was also needed to supply the substation with reliable AC power.
How many types of substation are there?
The different types of substations mainly include Step-up Type Substation, Step-down Transformer, Distribution, Underground Distribution, Switchyard, Customer Substation, and System Station.
What is difference between 11kV and 33kV?
The 11kV lines are used in residential areas and is what feeds the local transformers, which then distributes power to the buildings in the area. 33kV lines on the other hand involve much higher voltages and are used to distribute power from one small sub-station to another.
What does kV mean in electricity?
kilovolt
Definition of kilovolt : a unit of potential difference equal to 1000 volts.
What are the 3 battery types?
There are three primary battery types available for consumer use. They are alkaline, nickel metal hydride (NIMH), and lithium ion. Each type has its pros and cons. Each one also has a distinctive place in technology history.
What are the 2 types of batteries?
There are two basic types of batteries: primary and secondary. Primary batteries are “single use” and cannot be recharged. Dry cells and (most) alkaline batteries are examples of primary batteries. The second type is rechargeable and is called a secondary battery.
