Operation and Maintenance of 66KV Substation

What Is an Electrical Substation?
Electricity isn't delivered straight from the power station to your home. A process is needed to lower the voltage supplied from power stations to a safer, lower voltage which can be delivered to homes and businesses. It is the job of an electrical substation to present this task. The substation also manages the network to ensure it is working optimally and fault free.
What is creating in a Substation?The main section of a substation is a power transformer. The transformer is a device which is used to decrease or increase the voltage of the power fed to it. Switchgear is a key aspect of a substation to control and guard circuits, as well as raising the trustworthiness of the electrical supply, plummeting fault currents.

Circuit breakers are included to cut the power supply in case of a problem. When the circuit is disconnected, the circuit breaker pulls separately the contacts. A number of different property types can trigger this opening including oil, gas, vacuum and air.

• Oil relies on vaporization of oil to inject a shot of oil through the arc 
• Vacuum circuit breakers are frequently used in medium voltage switchgear as they have minimum arching
• Gas quench the arc using the power of the attractive ground
• Air circuit breakers use compressed air to satisfy the arc
• Whatever the material, circuit breakers can disconnect the circuit extremely quickly, from as little as 30ms.

The voltage of the electric current leaving a power station is 25,000 volts. The explanation of a substation is to boost or reduce the voltage depending on its location.

Huge Substations
To send the power across long distances a large substation increases the voltage for such a journey. High voltage currents leave a system substation on high overhead lines carrying insulators to ensure that the current doesn't travel to the ground.

Small Substations
In the country smaller substations are present to lower voltage to 33,000 volts. In more build up areas substations lower the voltage much more, between 11,000 and 33,000 volts. These substations directly deliver factories, hospitals and the rail network for pattern.

Extremity mounted transformers also live to lower the voltage to 230 volts, a secure voltage which can be delivered to homes. 11kv Cable End termination and Jointing
An electrical current may pass throughout several substations on the way to its goal.
