CAN anybody explain me the significance of testing operation times EHV CIRCUIT BREAKERS? Also if bounce/ chattering is observed during the timing tests , for how much duration bounce/chattering is allowed? what are ill effects of the chattering? or should we ignore it even if test instrument is indicating it's presence?

is there any iec standard with ref to chattering time?

Awaiting your guidance
