Line Switch Commissioning 101
There are many reasons why line switches do not work correctly over time. Utilities can avoid many operational issues if the component is specified for actual environmental exposure conditions and installed per the design requirements.
Reference Information
Selected Standards
This page lists selected standards related to overhead line switches (disconnect switches) and associated components, organized by components and year of publication. Descriptions of most listed documents are taken from the respective websites.
Calculators
Whip Testing (Web-based) a simplified software calculator has been developed to calculate the test circuit component values for a range of input parameters. With the known test circuit parameters, this software tool can also calculate the expected TRV transients and oscillation frequencies, that can be compared to oscillographs captured during testing.
