Dielectric testing is a evaluation process performed by applying a voltage to an electrical component that exceeds its normal operating voltage. The purpose of the test is to determine if a componentâs insulation is adequate enough to protect the user from electric shock.d. The most common type of testing is the dielectric breakdown test. In this procedure, a high voltage electrical current is applied to the component. The dielectric tester monitors the amount of current leakage during the test to determine if the insulation has failed.
With the development of the new 8-speed automatic transmission by ZF, the focus is not on the number of speeds but rather on the minimization of fuel consumption. There are a number of innovations that contribute to this development.
CVT = continuously variable transmission. That's a transmission that doesn't have gears and instead uses pulleys to generate the gearing desired.By doing it this way, they can be continuously varied to generate more than just a few specific gear ratios. manual transmission has gear sets that have a fixed ratio for each set--hence the five speeds. One ratio (speed) per gear set. The CVT is automatic or can be operated in a simulated manual mode (if it is electronically controlled) while you must disengage a clutch to manually shift a manual transmission. Source(s):
