    ABB protection IEDs are preferably tested by aid of components from the COMBITEST testing system described in information B03-9510 E. Main components are RTXP 8/18/24 test switch usually located to the left in each protection IED and RTXH 8/18/24 test handle, which is inserted in test switch at secondary testing.
