Test bench of RWA laboratory was upgraded. It facilitates to monitor all stages process chain of  manufacturing of automation and supervision systems. Test bench renders possibility to check the correctness of design and engineering solutions, monitor working efficiency of circuit components at all stages of science-research and design engineering works. At stages of procurement and installation it allows provide incoming control of apparatus and equipment. Such inside testing of components before their delivery to installation site provides significant reduction of period of start up and commission works and provide their fail free performance of the systems. In situations, when experts of RWAperform installation, start-up and commissioning outside of the Ukrainian territory, in short terms, or at operating stations laboratory testing of effective performance of components ensure successful performance of project. Presently, the functionality of test bench is renewed and enlarged due to capabilities to provide tests of components of lineup of TSX Quantum and М340 of M/s Schneider Electric.
