Patent ID: 8000933

Claim:
A power system comprising: a high voltage switchgear operatively connected to a power line, said high-voltage switchgear comprising two associated contacts which can be switched between a first position where they are coupled and a second position where they are separated; a switching device which is operatively coupled to said high-voltage switchgear for switching said contacts between said first and second positions substantially synchronously with said power line, wherein said switching device comprises a first computer device having code therein configured to: record data related to switching operations executed by said high-voltage switchgear; based on the recorded data, calculate values, E elect , indicative of the accuracy of the switching operations executed with respect to predefined target switching operations using the equation: E elect =t feedback −t target where t feedback is a value indicative of the time occurred for the executed switching operation and t target is a predefined target time for said executed switching operation; a second computer device in operative communication with said first computer device, said second computer device having code therein configured to: form a histogram using said calculated values; and show the formed histogram to a user.
