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.
The Vehicle Speed Sensor measures vehicle speed. If it fails or malfunctions the automatic transmission may not operate properly. It may also cause the automatic transmission to go into failsafe mode making it appear that the problem is more severe than it actually is.he Turbine Shaft Sensor measures the input shaft speed of the automatic transmission. The electronic transmission control module uses the information provided by the TSS to determine the amount of torque converter clutch slippage. If it fails it usually produces an automatic transmission fault code.
