Protection Testing Library

The OMICRON software technology including the OMICRON Control Center, XRIO, and LinkToXRIO enables users to create specific test templates which adapt automatically to the actual relay settings. This functionality is the technological basis of the Protection Testing Library (PTL), a comprehensive test template library for a wide range of protection relays. Using the PTL allows considerable time savings as test plans and nominal characteristics do not have to be created from scratch.

PTL's test templates contain complete test plans for all important protection functions, XRIO Converters and parameter import filters. 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. Finding a particular setting is quite easy because the structure of parameters is modeled closely to that of the relay software. In addition, special filters allow the relay settings to be imported directly from the relay manufacturer's software.

The PTL test templates are developed by OMICRON experts and external specialists. The content of the library is continuously extended and maintained. Therefore users of the PTL can also benefit from the extensive application knowledge included in the test templates. 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.

The PTL is part of the Test Universe software DVD and available for free download in the Customer Area.
