Insulation Online Monitoring Method for Dry-Type Current Transformers Based on Virtual Voltage

Insulation Online Monitoring Method for Dry-Type Current Transformers Based on Virtual Voltage

To improve the accuracy of insulation state online monitoring for capacitive dry-type current transformers (CTs) and to address the limitations of traditional methods relying on potential transformer (PT) voltage signals and reference devices, a virtual voltage-based online monitoring method is prop...
