发明名称 Current rail support isolator
摘要 The support isolator (4) has a sensor device for detecting at least one electrical parameter of the current rail, with a material part of the sensor device (6,7) incorporated in the seating for enclosing the current rail at the upper end of the support isolator. Pref. the sensor device uses an annular electrode (6) capacitively coupled to the current rail for measuring its voltage and a Rogowski coil (7) for inductively measuring its current
