Power Transformer Generation of electrical power in low voltage level is very much cost effective

this low voltage level power can be transmitted to the receiving end. This low voltage power if transmitted results in greater line current which indeed causes more line lossesBut if the voltage level of a power is increased, the current of the power is reduced which causes reduction in ohmic or I2R losses in the system

reduction in cross sectional area of the conductor i.e. reduction in capital cost of the system and it also improves the voltage regulation of the system. Because of these, low level power must be stepped up for efficient electrical power transmission. This is done by step up transformer at the sending side of the power system network.


Switchgear are favorably priced high-voltage substations

They are popular wherever space restrictions and environmental circumstances

from Siemens are renowned for highest reliability, economical operation, and low maintenance requirements. is an integrated provider of high-voltage systems for more than 80 years and also supplies particularly space-saving, compact and even portable air-insulated switchgear solutions


Electrical Application

they are classified into different types: Generation substation Indoor substation, Outdoor substation, Pole mounted substation, Switching substation, Transmission substation, Converter substation and Distribution substation

n rare cases like wind farm power generation system, multiple hydroelectric and thermal power plants one can observe the collector substation which is used for transferring power from multiple turbines into one transmission unit.
