Switchgear Testing Guidelines and Values by anjna is a document available to read on EtoBox.

The document summarizes information from three training sessions on switchgear: 1) It provides the recommended megger and PI test values for low and high voltage motors, with minimum acceptance levels. 2) It lists the typical contact resistance ranges for various voltage circuit breakers up to 735kV. 3) It specifically calls out the contact resistance values followed at an AREVA factory for 6.6kV vacuum circuit breakers of different amperages. 4) It concludes by stating the contact resistance values
