Substations & transmission lines are part of an electrical generation, transmission, and distribution system. Substation components such as CTs, VTs, PTs and ground grid must be tested for their performance during substation commissioning. The grounding system in substation is very important as it protects the substation equipments from surges & lightning strikes and also protect the operating persons. Transmission lines plays important role in power distribution.
Losses due to Ineffective Control Systems:
- Power outage.
- Equipment health deterioration.
- High-stress generation during sparking or flashover
- May lead to a cascading series of shut downs and a major regional blackout
