VOLTAGE SURGE
This test requires 160 volts output. If the power source is set at the low voltage range, the high
voltage range will be selected before the test starts. At the end of the test, the power source will
be switched back to the low range automatically

The output voltage will follow the sequence in Table 9-4. The above sequence will repeat itself
three times. Each repeat will start from sequence two. US and Group 1 will run at 400 Hz.
Group 2 and Group 3 will run at 360 Hz and 650 Hz for Group 2 and 800 Hz for Group 3. The
frequency will return to the nominal setting when the test is completed. The
will terminate the test at any time.
