The grounding system in substation is very important as it protects the substation equipments from surges & lightning strikes and also protect the operating persons. Substation components such as CTs, VTs, PTs and ground grid must be tested for their performance during substation commissioning. Fire Wall & Oil Separator Pit for the EFLs Sigatoka Substation Energy Fiji Limited.Substations & transmission lines are part of an electrical generation, transmission, and distribution system.
High-stress generation during sparking or flashover Intersterization for disconnection and grounding in safety are used when the staff is The following are major electrical components of substations and their working.Other components of the transmission substation include various types of switches and relays to the control power, as well as a variety of protection equipment such as overvoltage waste in case of lightning. Multiple thermal and hydropower plants connected together for transfer of power to a single transmission unit from numerous co-located turbines. Losses due to Ineffective Control Systems:There is a need of collector substation as well in cases of large power generating systems e.g.
