How to Solve Single-Phase Grounding Fault Judgment for 3-Phase 4PT in Ungrounded Systems？

Four Fast In 10 kV and 35 kV ungrounded systems, single - phase grounding faults cause minimal current, so protection rarely trips. Per regulations, operation is limited to 2 hours; prolonged undetected faults may worsen, even damaging switches. While the State Grid promotes small - current grounding line selection devices in 110 kV and 220 kV substations, their accuracy remains low, requiring monitoring/operation staff to analyze remote measurements. For ungrounded systems with three - phase 4PT voltage

How Does Temperature Change Affect AIS Voltage Transformers？

Four Fast Impact on Insulation Performance Changes in Insulating Material Properties: AIS voltage transformers rely on air as the insulating medium, and they also contain some solid insulating materials, such as insulating paper and insulating bushings. When the temperature rises, the migration and evaporation of moisture in solid insulating materials like insulating paper will accelerate, resulting in a decrease in the electrical strength of the insulating materials and an increased risk of insulation br
