摘要

A method for correcting a by means of an electrical voltage measurement is carried out indirectly electrical current measurement with the use of a shunt resistance state (4), wherein the method, a correction of the resistance value of the shunt resistance state (4) with respect to the current ambient temperature (t_U) , characterised in that the correction method of the further a correction with respect to the through the due to the current flow in the shunt resistor (4) which is generated power loss (p) to increase the temperature of the shunt resistance state (4) contains, for which properties of the heating caused by the flow of current correction of the intrinsic heating of the shunt resistance state (4) by folding a from the measured voltage (u_Measuring) determined power loss (p) as input variable with the impulse response of the shunt resistor system is simulated.
