Ferroresonance leads to a high saturation of the transformer core. This causes severe rise of
the amplitude of current and voltage of the transformer and leads to current and voltage non …

Inductive voltage transformers (VTs) are the most widely used instrument transformers in
power grids operating at 35 kV and below. Frequently, however, during disturbances, the …

Ferroresonance is a common and complex phenomenon in power systems. Some types of
ferroresonances are remarkably difficult to distinguish from others. This study adopts non …

This study employs a novel smart solid state ferroresonance limiter (SSFL) for stabilising the
chaotic behaviour of a voltage transformer (VT). It is shownthat the ferroresonance …

Ferroresonance, excited by saturated electromagnetic voltage transformers, can severely
damage power systems because it produces long duration large overvoltages. In this paper …

Ferroresonance, which is a common phenomenon in power systems, have threatened the
security of power systems for a long time. Although several ferroresonance suppression …

Non-contact voltage sensors based on the principle of electric field coupling have the
advantages of simple loading and unloading, high construction safety, and the fact that they …

This study presents a simulation model for a ferroresonant circuit. The proposed model
includes a transformer model and a vacuum circuit breaker (VCB) model. Hysteresis …

The occurrence of ferroresonances, due to the presence of voltage transformers in isolated‐
neutral in medium‐voltage (MV) distribution grids, results in overvoltages and overcurrents …

The paper presents a reduced form of the algorithm for converting a measured RMS
transformer characteristic into the corresponding peak instantaneous transformer saturation …
