Electrical Substation DefinitionNowadays, the demand for electrical power is growing rapidly. To meet this demand, we need larger power generating stations, which can be hydro-electric, thermal, or atomic. These stations are built in various locations based on resource availability, often far from the areas where power is consumed.Therefore, it’s necessary to transmit power from generating stations to load centers using high-voltage networks. Power is generated at low voltages but transmitted at

Electrical Power Distribution System DefinitionAn electrical power distribution system is defined as a network that delivers power to individual consumer premises at a lower voltage level.An electrical power distribution system provides power to individual consumer premises. The distribution of electric power to different consumers is transmitted via a much lower voltage level compared to the transmission of power over long distances (i.e. over long transmission lines).The distribution of electr

What is a Distribution Transformer?Distribution Transformer DefinitionA distribution transformer is defined as a step-down transformer used to distribute electric power efficiently to consumers.Types of Distribution TransformersThese include single phase, three phase, pole mounted, pad mounted, and underground transformers, each serving different purposes.Secondary TerminalsDeliver electrical power to consumers and are connected through a fuse unit for protection against faults.All Day Efficienc

Previously there was very little demand for electrical energy. A single small electrical generating unit could meet the localized demand. Nowadays the demand for electrical energy is tremendously increasing along with the modernization of human lifestyles. To meet this increasing electrical load demand, we have to establish quite a large number of big power plants.But from the economic point of view, this is not always possible to build a power plant nearer to the load centers. We define load ce

It can be of three (3) types of electric cable faults found. They are There may be a short circuit between two conductors, There may be earth fault, i.e., fault between conductor and ground, There may be open circuit caused due to disconnection of the conductor.There can be more than one of the faults at a time.The primary cause of the 1st and 2nd fault is due to damage of insulation caused by water, moisture or other reason. Due to the defect in the armour, plumbing or the lubricant compound ge

For carrying of overhead line, wooden poles, concrete poles, steel poles and rail poles are used. Which poles are to be used, depending on the importance of load, location, and place, cost effect of such construction, including maintenance cost, and keeping its profit element in mind. In low voltage line for all phases, natural and earth we use single pole line. There are different types of poles used in the electrical system. These poles are Wooden Electric Pole Concrete Electric Pole Steel Tub

What is Load Factor?In electrical engineering, the Load Factor is defined as a ratio of the average load divided by the maximum (or peak) load in a given time of period. In other words, the Load Factor is the ratio of total energy (kWh) used over a specific period of time to the total possible energy available within that period (i.e. peak demand over that specific time period). Load Factor can be calculated on a daily, monthly, or yearly basis. The equation of Load Factor is;The Load Factor is
