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.[email protected]

Switchgear - Wikipedia switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.Get Price
