What factors do you consider when selecting distribution equipment?

1 Voltage level

One of the first factors that you need to consider is the voltage level of your distribution system. The voltage level determines the type and size of the distribution equipment that you need, as well as the insulation and clearance requirements. Generally, higher voltage levels require more robust and expensive equipment, but they also reduce the power losses and the current flow in the system. You should choose the voltage level that best suits your design objectives, load characteristics, and site conditions.

3 Protection and coordination

A third factor that you need to consider is the protection and coordination of your distribution system. The protection and coordination refer to the design and operation of the distribution equipment that prevent or minimize the damage and disruption caused by faults and overloads in the system. You should select the distribution equipment that can detect and isolate faults quickly and selectively, without affecting the rest of the system. You should also coordinate the settings and characteristics of the distribution equipment to avoid unnecessary tripping and cascading failures.

4 Reliability and redundancy

A fourth factor that you need to consider is the reliability and redundancy of your distribution system. The reliability and redundancy refer to the ability of the distribution system to maintain or restore power supply in the event of failures or contingencies. You should select the distribution equipment that can enhance the reliability and redundancy of your system, such as automatic reclosers, sectionalizers, switches, and backup generators. You should also consider the configuration and topology of your system, such as radial, loop, or network.
