Maconic Shunt Resistors

The currents to be measured are associated with system voltages (potentials) which must be safely separated, i.e., galvanically isolated by the shunt isolator. Here, it is important that the voltage measurement is not affected by common mode influences. This can be achieved even for shunt voltages as low as 60 mV by suitably designed shunt isolators. Higher shunt voltages are not necessary with high-quality shunt isolators and because of the physically larger shunt resistors, they are generally not desired.
