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.
In the 911, it's a seven-speed manual like the Corvette's. Porsche is also one of the only manufacturers to spend any money to improve the manual transmission, and what's most amazing is they did so for the mere 30 percent of 911 buyers who still like to row their own gears.he new 7-speed manual transmission (an 8-speed automatic is optional) is one of the best hooked to any V8. That's true even for the top-of-the-line Z06 model, which makes a rather astonishing 638 hp from its supercharged V8 and, when shifted by an expert tester, can hit 60 mph in just 3.3 seconds.
