High-quality printed outputs on a large variety of printers and plotters. Detailed modeling of distance relays using make- and model-specific parameters and operating logic. The leading aspwn circuit and relay coordination system. Automatic plotting of overcurrent and distance relay characteristics on the screen, as well as fault-based time-distance diagrams for all relay types. OneLiner is a productivity tool.

Graphical display of post-fault solution and relay operating time on the one-line diagram and the phasor diagram. Automatic checking of overcurrent and distance relay coordination, plus automatic checking of overcurrent relays' pickup and instantaneous settings.

Accurate modeling of 2- and 3-winding lneliner shifters, lines, switch, series capacitors with and without nonlinear MOV elementsgenerators, loads, shunts, dc lines, and zero-sequence mutual coupling.

It relieves the engineer from the tedious and time-consuming tasks of leafing through stacks of printouts and plotting and re-plotting relay curves and one-line diagrams. Detailed modeling of fuses, reclosers, and overcurrent relays.

Unlimited system size with modest memory requirement. OneLiner works very quickly under the control of the engineer.

Built-in boundary equivalence program. Built-in short circuit program that simulates apen classical fault types bus faults, and close-in, line-end, line-out and intermediate faultsas well as simultaneous faults arbitrary collections of classical faults, plus phase-open and bus-to-bus faults. Parallel processing on muti-core computers.

Tools for PRC compliance: Modeling of VSC converter. Modeling of over- and under-voltage protection relays. The following are some highlights of OneLiner: The engineer can change the relay settings and network configuration and see the results of the change immediately.

Modeling of line differential protection schemes. Modeling of current-limited generators for wind and solar plants. Native Microsoft Windows program.
