What is the most important thing in a substation?
Lightning Arrester Lightning arrester is a most important protective device of distribution substation to protect valuable equipment as well as working personnel. It arrests and discharges over voltage to earth during lightning strokes.
What is the job of a substation?
Substation Superintendent 5 years of experience as a heavy electrical foreman or superintendent building and/or modifying electrical substations is preferred.
What does a substation maintainer do?
Under general supervision, the Substation Maintainer performs journey level tests, maintains, repairs, and overhauls electrical substation equipment.
What are the duties of a substation technician?
Substation technicians install wiring systems and control panels, as well as perform routine maintenance and emergency repairs on electrical substations that send energy into nearby homes and buildings. In this role, you may collaborate with architects and engineers to develop the layout and plan of the substation.
What is DC substation?
Subscribe. DC Substation Solutions. For Metal Processing Applications. GE’s Direct Current (DC) substation solutions are custom designed systems that provide highly reliable and efficient DC voltage and current for specific metals processing operations.
Why do substations have batteries?
A substation battery charger ensures all the essential electrical systems in a substation continue to operate in the event of a power outage. An absence of an electrical supply could result in damage to equipment and personnel.
What is a substation and how does it work?
A substation is an electrical system with high-voltage capacity and can be used to control the apparatus, generators, electrical circuits, etc. The Substations are mainly used to convert AC (alternating current) to DC (direct current). Some types of substations are tiny in size with an inbuilt transformer as well as related switches.
What is the voltage between two phases of a substation?
The voltage of any two phases will be 400 volts, and the voltage between neutral and any phase will be 230volts. This type of substation is placed at different points in an electrical network. They can connect different parts of the network and that are a source of sub-transmission or distribution lines.
What is the difference between service rendered and operating voltage substations?
The service rendered based substations are service rendered which includes a transformer, switching and converting substations. The operating voltage based substations are high voltage, extra high voltage, and ultra-high voltage substations. The importance based substations are grid and town substations.
What is the difference between substation and load center?
Based on the availability of different resources, substations are building at different locations, but these locations may not be closer to load centers. The actual power utilization can be done by the load center. So it is essential to transmit the power from the substation to load center locations.
