摘要： The invention relates to a current measuring apparatus for redundant measurement of an electric current (I) with a low-resistance current measuring resistor (1) for current measurement according to the four-lead technique and with a magnetic field sensor (14). The invention provides that the electric current (I) to be measured in the current measuring apparatus is divided into a main current path with a main current (11) and a secondary current path with a secondary current (12), the main current path and the secondary current path together forming a parallel circuit. The low-resistance current measuring resistor (1) is arranged in the main current path and has the main current (11) flowing through it, while the magnetic field sensor (14) is arranged in the secondary current path and measures the secondary current (12).

摘要： The invention concerns a resistor, in particular a low-resistance current measuring resistor, having two connecting parts made of a conductor material and a resistor element made of a resistance material inserted between the connecting parts, the resistance material having a specific thermal force which generates a specific thermoelectric voltage in the event of a temperature difference between the resistor element on the one hand and the connecting parts on the other hand. The invention additionally provides for a compensating element which in operation generates a thermoelectric voltage which at least partially compensates for the thermoelectric voltage generated by the resistor element. Furthermore, the invention includes a corresponding manufacturing process.

摘要： The invention relates to a resistor, in particular a low-resistance current-sensing resistor, with two connection parts made of a conductor material and a resistor element made of a resistor material. Furthermore, the resistor has two pairs of voltage measuring contacts for measuring the voltage dropping across the resistor element in two separate voltage measuring channels. The invention provides that the two pairs of voltage measuring contacts are arranged crosswise so that a connection line of the two voltage measuring contacts of the first pair of voltage measuring contacts intersects with a connection line of the two voltage measuring contacts of the second pair of voltage measuring contacts in a top view of the resistor.
