6.6Kv Switchgear CFPP 2X30Mw Amurang: Insulation Test, Contact Resistance & Timing

This document summarizes test results for a 12kV switchgear CB panel. Insulation resistance tests found resistances between 16-30 GOhms when closed and 88-97 GOhms when open. Contact resistance tests found values between 15-17 uOhms. Timing tests found close times around 51ms, open times around 39ms, and close-open times around 42ms, all within specification. The tests were performed using calibrated equipment and the switchgear was found to comply with specifications.
