The H24005 power suppply and a lightning strike
« on: March 15, 2019, 01:52:35 am »
About 5 weeks ago during a fairly nasty fire season in Victoria we were also hit by a series of lightning strikes. One came close to our house.  :--

It appears that current travelled up through the earth leakage device on the switchboard and took out all sensitive earthed appliances. All two pin appliances survived. :bullshit:

The same switchboard feeds another switchboard some 70 metres away in my workshop. The H24005 was connected. When doing the damage assessment I came to the H24005 with 2 blown fuses, replacement of the fuses saw the new earth leakage device (yes it blew too) trip again.

To make a long story short, replacement of the 2 TVS devices (and 2 more fuses) saw my baby come back to life. I suspect also that the H24005 sacrificing itself may well have saved other appliances in the workshop. Thankyou Prasimix.

Does anyone think I should also replace the MOVs too?

A MOV generally degrades as it absorbes each power surge. So if in doubt on how much lifespan is left in them, just change them out.
