Efficient setting-based testing with the Protection Testing Library (PTL) 


As OMICRON’s protection experts continuously update and extend the PTL, users can now benefit from test templates for more than 360 relays.
With the latest update of the PTL all SEL PTL items have been enhanced with a new integrated guided workflow, and the new PTL items for: 

  • SEL 311L
  • SEL 411L
  • SEL321
  • SEL 421 and
  • SEL 351S

are now available.
Specifically tailored for OMICRON’s CMC test sets and the Test Universe operating software, the Protection Testing Library helps users save valuable time, since test plans and nominal characteristics do not have to be created from scratch.
