tandem bridge

A tandem bridge is an electronic device used to measure electrical currents with high precision, often in complex systems such as power grids or laboratories. It consists of two connected measurement paths (bridges) that work together to compare the unknown current against a known standard. By balancing these two paths, the tandem bridge can detect very small differences in current accurately. This configuration improves measurement sensitivity and reduces errors from external influences, making it ideal for precise calibration and testing of electrical components and systems.
