Parallel operation of transformer means HV and LV of two (or more) transformers are connected to the source busbars and load busbars respectively. Busbar design is still resistance/heat engineering: thickness, width, material, and mounting affect performance. To achieve the maximum tot l output, the individual voltage sources must however have the same data. With unequal no-load voltages within the parallel circuit, a. The high magnitude fault currents require high-speed operation of the busbar protection to limit equipment damage. However, this high-speed clearing must be balanced against the need for security. It not. In high-power applications, such as industrial motor drives or renewable energy systems (e. Solar, Energy Storage Systems), it is a common practice to employ multiple IGBTs in parallel to distribute the load.
