Shunt element for measuring current comprising compensation means |
摘要 |
In order to minimize the effect of return current flow on a current measuring shunt, the present invention proposes a shunt having a compensation circuit to compensate for the asymmetrical effect of such return currents. Such compensation is provided by two measuring circuits which are to measure the voltage drop across the shunt, and each circuit is located in a median plane of the shunt. The path of each of these measuring circuits is optimized and established in the calibrated configuration of the shunt. These parallel measuring circuits also have their inputs and outputs connected together respectively. Particularly, the present invention relates to shunts having a tubular or rectangular configuration and including such compensation circuits.
