Safety by design: solid insulated technologies challenge ...· PDF fileapplication of 10 MVA distribution transformers as shown in Fig. 1, the 4.16 kV switchgear interrupting rating would need to be 10 MVA/(1.73 X 4.16 kV)/0.0575 = 24.1 kA. Both are significant interrupting ratings for this class of switchgear. Historically, SF6 has been applied by utilities in high-voltage systems above 38 kV.Get Price
ABB's optimised instrument transformers and sensors design ...· Split-core design is an important feature for transformers because it enables power grid maintenance without any disruptions. ABB set out to design a split-core current transformer (sensor) that allows high-accuracy current measurement while the switching is done by other devices and the need for switching is evaluated by IED based on signals from the sensor.Get Price
