Assertion: grading ring | /r/CapableOf | reduce the gradient
Facets:
value: at the end
type: TEMPORAL
Source sentences:
text: It reduces the gradient at the end, resulting in a more even voltage gradient along the insulator, allowing a shorter, cheaper insulator to be used for a given voltage.
text: Grading rings also reduce aging and deterioration of the insulator that can occur at the high voltage end due to the high electric field there.
