Hi all
Can you tell me if there is a cheap and easy way of testing an earth electrode, without the expense (which I can't afford yet!!!) of buying a dedicated tester?
This is one person's recommendation, tell me what you think:
"Anyone with a bit of electrical common sense, knowledge of Ohm's law, and a decent multimeter can measure earth electrode resistance quite easily. You need to isolate the electrode in question and then find a way of getting some current to flow into it. A safe way to do this is to use a double-wound mains transformer with a secondary voltage of around 24V (exact value not critical). It is preferable to use AC for this test since that eliminates any electrolytic effects (if you must use DC source such as a car battery, then conduct two readings, reversing the polarity for the second)."
I don't fully understand this, but you have more experience than me, perhaps a diagram, or an easy explanation?
I have just passed my 2382-12, with 90%, came top in my class. I'm delighted!! :rockon:
Any congratulations happily received!!!!! :grouphug: :musical_note: :musical_note:
