Ramp Measurement (Ramp Voltage Test)
4.4 Ramp Measurement (Ramp Voltage Test)
Used to determine whether the insulation resistance of an object under measurement
is a󰀨ected by a change in test voltage, in the same manner as the step voltage test.
This test subjects the object under measurement to less stress than the step voltage
test because the test voltage is continuously increased in a gradual manner.
(Reference standard: IEEE 95)
Overview of test
The applied voltage in the insulation resistance measurement is gradually raised until
it reaches the set voltage. The measurement automatically ends once the applied
voltage reaches the set voltage.
Default setting: 1000 V/min
