4.5.4 Pulse Control Mode
The pulse control mode is recommended for troubleshooting
(locating the point of flashover).
Breaking current I
MAX
is set to a fixed value of approximately
125 mA for the 204HP and 5 mA for the 204HV in the pulse
control mode. If this value is exceeded, test voltage is switched
off within 0.5 ms. After approximately 0.6 s, test voltage is
increased from 0 to the selected maximum value within a period
of 0.2 s, or is switched off again if breaking current is exceeded.
➭ Set I
MAX
to >>>>>>> for selection of the pulse control mode
(see chapter 4.5.2, page 37).
➭ If continuous operation is required, set test duration to >>>>>>>
as well (see chapter 4.5.2, page 37).
4.5.5 Ending the Voltage Test
