Short Circuit Modeling in ASPEN or CAPE
PC-based short circuit and relay coordination program for relay engineers. OneLiner is a productivity tool. 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. OneLiner works very quickly under the control of the engineer. The engineer can change the relay settings and network configuration and see the results of the change immediately.
Protection and Control Design
PhasorGrid has significant experience in protection and control design with many thousands of LV, HV and EHV protection and control systems in use throughout the world. Its wide experience and in-depth expertise in protection and control design enables it to design the most complex power system schemes as well as providing elegant, simpler schemes for less arduous applications.

Relay Design and Settings Standardization
If Settings and Designs are not standardised, it is very likely that human error or a technical overlook will occur, which may cause a major breakdown in the power system. We can help your organization develop standardised templates for the protection of all your power system elements.
