It measures Meg ohms, it generates a high voltage, very small current
measures up to 100M ohms or more.

I guess its the same reason I keep my Klenex on the Frigidare.


In the US I most often hear them called hipot testers... another brand name

It measures Meg ohms, it generates a high voltage, very small current
measures up to 100M ohms or more.

Or it might be called a megger because it produces about 1 million volts dc.
If it produced a thousand volts, they'd have to call it a killer!

Wasn't there also a company making insulation testrers called Meggar? Bit
like vacuum cleaners being called Hoovers.

As in, "Who has the AVO?" - just as the word AVO has become
synonymous with multimeter, Megger has become so for a high
voltage tester.

"Manufacturing insulation testers from 1kV to 10kV is where
the company Megger started, and the Megger brand name is so
well know today that maintenance professionals often
incorrectly use it as a verb when they refer to doing an
insulation test on wiring. This famous brand name dates back
to 1889, when the first portable insulation tester was
introduced with the MEGGER brand name on it. The firm enjoys
an outstanding reputation in the areas of ground testing,
oil testing and a wide variety of electrical contractor
maintenance tools such as multimeters portable appliance
testers and clamp-on meters."

It is, of course, part of AVO International.


My Megger was "handed down" to me by my great-uncle and
dates from 1935. It still works perfectly and has a current
type III calibration certificate...

Last machine I used (Fluke) it went into GIG ohms. Not that any one really
cares at that level.

I'll second that! Ever come into contact with the leads, or the length of RF
transmission line being tested, and you will call it at the least a major
OWWWWIE. Teach me to be complacent when NOT dealing with a Hi-Pot!
