The Resiliency Continuum
Storm damage can wreak havoc on the electrical distribution system and instantaneously create a major impact on those who continuously depend on unfettered access to electrical energy. “Keeping the lights on” is a bedrock principle of utility operations, but is increasingly being challenged by more frequent and turbulent natural disasters. The quest for greater utility […]

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 […]

Assessing the impact of transmission investments on the Italian Ancillary Services Market using MODIS simulator
The justification of transmission investments is becoming more complex and challenging with respect to the past decades since environmentally friendly solutions shall be adopted and the benefits for the society must be clearly highlighted and quantified. Clear and objective indicators of the benefits arising from transmission projects are playing a key role to foster the […]

Issues related to spark discharges
In the general public environment, ambient power-frequency electric fields are relatively small, except when near high-voltage (HV) transmission lines. Electric fields from aerial HV transmission lines are greatest directly under the conductors and decrease with. In occupational environments, elevated electric fields also exist in HV substations/switchyards, and in particular under busbars/equipment. Other sources of power-frequency […]
