Sensor system for measuring electric current and voltage esp. for medium voltage conductor and ohmic voltage divider for voltage measurement also capacitive voltage divider

摘要

The ohmic voltage divider (5) and the capacitive voltage divider (6) for the voltage testing are arranged together in a combination unit (1) along with the prim. conductor (4) and the current sensor (3). The sensor, the prim. conductor and the two dividers are cast in a block of casting resin.The current sensor is designed as an inductive current sensor with a wire coil (7) arranged around the prim. conductor. The prim. conductor is designed U shaped in the combination unit, and both its ends are led through on the upper side of the combination unit
