How to handle 35kV busbar PT resonance
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. Abstract— It is shown in this paper that single-phase fault s in a 110 kV supply network result in the occurrence of resonant overvoltages, which are dangerous for substation equipment at the 35 kV side where capacitive current compensation via Petersen coils is used. Analysis after on - site investigation: 1. Common methods of protecting busbars include overcurrent-based interlocking schemes, overcurrent-based differential protection, high-impedance differential protection, and percentage differential protection. The series resonance withstand voltage test is a critical step in ensuring the insulation performance of high-voltage equipment such as 35kV cables used in prefabricated substations (commonly referred to as “box transformers”).

10kV busbar section grounding fault
When the electrical bus bar insulator suffers insulation damage, it can lead to a ground fault in a 10kV busbar at best, and a phase-to-phase short circuit at worst, causing extensive power outages and potentially severe consequences to the distribution network. The high magnitude fault currents require high-speed operation of the busbar protection to limit equipment damage. The proposed scheme successfully detects single-phase-to-ground busbar faults by using the standard settings of the wide y available overcurrent IEDs, and an IEC 61850 communication between them. Additionally, ferroresonant overvoltages (several times normal voltage) may occur, breaking down insulation and causing major. Also, in the case busbars sections are separated, only one section needs to be isolated to clear a fault. Busbar protection is actually the strongest when bus sections are separated.
