...current. therefore, the first three channels remain for the overcurrent protections; for autotransformer/busbar/generator/reactor/motor applications, the first three (1st – 3rd) channels of ct+/5116 current module can detect the peaks of the differential currents, so the module can be only used for high impedance differential protection. more technical details can be found on the related product page:  https://www.protecta.hu/protecta_products/smartline/s24/variant-7  

  hsbt is a control ied made for realizing high speed bus transfer for busbar sections supplying induction machine load; the device provides solution for bus transfer applications where quickness might be a crucial factor even to a point of a live bus transfer. in addition, the function takes into consideration the changing voltage and frequency of high power induction motors operating on the unsupplied busbar by controlling the moment of switching in order to avoid high current
