Gravels are used in switch yards to provide a stable surface for equipment and to improve drainage.
Gravels help in reducing the risk of equipment damage due to flooding or standing water.
They also help in preventing erosion and maintaining the stability of the ground.
Gravels are easy to install and maintain, making them a cost-effective option for switch yards.
They allow for better heat dissipation, which is important ...
A Single Line Diagram (SLD) of a 33/11 kV switchyard shows the layout and connections of electrical equipment.
Key equipments include transformers, circuit breakers, isolators, busbars, surge arresters, and control panels.
Transformers step down voltage from 33 kV to 11 kV for distribution.
Circuit breakers protect the system from overloads and short circuits.
Isolators are used for isolating equipment for maintenance.
Busb...
OC and SC tests are conducted on transformers to determine their efficiency and performance under different load conditions.
OC test (Open Circuit test) is conducted to determine the no-load loss and magnetizing impedance of the transformer.
SC test (Short Circuit test) is conducted to determine the full-load copper loss and equivalent resistance of the transformer.
Both tests help in evaluating the efficiency and voltage...

Different cable types have varying current carrying capacities and methods of laying, impacting overall electrical system performance.
Different cable types such as PVC, XLPE, and rubber have different current carrying capacities.
Current carrying capacity is influenced by factors like conductor size, insulation material, and ambient temperature.
Methods of laying cables include direct burial, conduit installation, and ov...
