The Branch Current Balancing Devices, LV busbar, MV busbar, LV distribution panel etc. with very low impedance. temperature rise test of distribution systems etc. It is used to adjust the rated currents of the busbars and/or the functional units on these busbars very quickly and easily during the loading tests. The device has 3 independent test outputs with a maximum capacity of 1000 A and a minimum of 250 A. These outputs can be connected to test samples with a rated current of up to 1000 A.
