35kV busbar PT burns out at wind farm

A 35 kV PT explosion in a thermal power plant caused busbar outages and grid risks. Explore root causes, fault progression, protection response, and how to prevent similar failures with insulation testing and resonance overvoltage mitigation. This article introduces a case of 35kV ring main unit. With the increasing use of wind turbines as a renewable energy source, it is important to address the potential risks associated with arc flash incidents. Study the wiring structure of the 35kV system of the wind power, the actual operation of the wind power, the restrict of. A busbar protection must be capable of clearing all phase-to-earth faults, and in the case where they can occur, phase-to-phase faults. The Partial Discharge test is crucial for determining long-term part performance and discovering inefficiencies in power transfer.
