Measuring transducer

摘要

The measuring transducer (1) which is provided in particular for measuring on busbars and cables of power distribution networks has a voltage sensor (6) which can be coupled capacitively to the busbar or the cable core and a current sensor (4) which responds to the magnetic field which surrounds the busbar or the cable core. In addition, it has an electronic signal pre-processing system (11) to whose input the voltage sensor and the current sensor (4) are connected, and a microcomputer which is connected downstream of said electronics. <IMAGE>
