Ferroresonance in Inductive Voltage Transformers Or Power Voltage Transformers: analysis, laboratory tests and solutions
A ferroresonance analysis related to HV Inductive Voltage Transformers (IVT) and power Voltage Transformers or Station Service Transformers (PVT/SST) was addressed to develop models based on EMT formulation, enabling detailed ferroresonance risk analyses in specific HV station conditions and helping in the equipment technical specifications (including anti-ferroresonance remedial provisions). The research relied on a comparison […]
