Abstract	Currently, power demand in the world has grown at a rate faster than the infrastructure development. This has caused the power system network to be stressful that could disrupt system stability leading to voltage collapse in the entire system. This incident led to a cascading blackout in the whole system and required a voltage stability analysis to be properly conducted. Line outage in a power system could also lead to the event of voltage collapse which implies the contingency in the system. Line outage contingencies are ranked so that the line which highly affects the system when there is an outage occurs in this line in terms of voltage instability could be identified. The contingency ranking process can be conducted by computing the line stability index of each line for a particular line outage and sort them in descending order. The contingency which is ranked the highest implies that it contributed to system instability. This paper presents a new voltage stability index referred to a line used to rank the line outage contingency. The information from the contingency ranking indicates the severity of the voltage stability condition in a power system due to line outage.
