    SWITCHGEAR One of the long-term trends in MV switchgear design has been towards smaller size. In conventional switchgear, current transformer (CT) and voltage transformer (VT) takes a significant part of the total volume of the cubicle. The volume of the sensors is less than 1/3 of the volume of conventional instrument transformer.
