![]() The PTL test templates are customizable for specific needs and the XRIO converters can be used in user-created test plans as well as single tests. ![]() Therefore users of the PTL can also benefit from the extensive application knowledge included in the test templates. lead engineer for new product development of pad-mounted and overhead switchgear, integrating eight new configurable control cabinets with three different sel relay families (751, 451, and. The content of the library is continuously extended and maintained. The PTL test templates are developed by OMICRON experts and external specialists. In addition, special filters allow the relay settings to be imported directly from the relay manufacturer's software. Attach the rear panel (new if applicable) and reconnect the terminal blocks and CT/PT wires. Remove the card from its slot and insert the new card. Disconnect the terminal blocks and CT/PT wires. Finding a particular setting is quite easy because the structure of parameters is modeled closely to that of the relay software. Finally Hardware-in-the-Loop validation of the model is done by using the overcurrent protection feature in Schweitzer Engineering Laboratories Relay SEL-487E. Use a ground strap between yourself and the relay. ![]() The XRIO Converters model the protection characteristics and tolerances (e.g., impedance zones, I/t diagram shape, etc.) based on the parameters and technical data documented in the manual of the protection device. PTL's test templates contain complete test plans for all important protection functions, XRIO Converters and parameter import filters.
