Frequently Asked Questions - SWG 505 Megger
What is the Megger SWG 505 used for?
The SWG 505 is a surge withstand tester used to verify the insulation coordination of electrical equipment by applying high-voltage impulses.
What is the output voltage range of the SWG 505?
The output voltage is adjustable from 0 to 5 kV peak with both positive and negative polarity.
What waveform does the SWG 505 generate?
It generates a standard 1.2/50 μs impulse waveform as per IEC 60060.
How do I connect the test leads?
Connect the high-voltage output to the device under test using the supplied shielded cable. Ensure the ground connection is secure before operation.
Can I use the SWG 505 on DC systems?
Yes, but only after confirming the impulse voltage does not exceed the DC system's rated insulation level.
What safety precautions should I take?
Always disconnect power from the test object before connecting leads. Wear insulated gloves and use only on de-energized circuits. Follow IEC 61010-1 guidelines.
How often should the SWG 505 be calibrated?
It is recommended to calibrate the SWG 505 annually or after 1000 hours of operation to maintain accuracy.
What is the maximum repetition rate?
The maximum repetition rate is 1 impulse per second (1 Hz).
Can I replace the high-voltage cable myself?
Only use approved replacement cables from Megger. Contact an authorized service center for replacement to ensure safety.
What does the error code 'E01' mean?
Error code E01 indicates an internal fault. Cycle power; if it persists, return the unit for service.
