Cheap high voltage insulation tester
« on: November 22, 2017, 03:38:16 pm »
Hello,
We need an end-of-line tester for our offline led lamps production line. (40 to 150W)
All it does is take the impedance between Mains Live/Neutral and Earth.
-And yet it costs £6000.
Why are they so expensive?
Do you know of a cheaper one?
Our production staff are having to share one and they are almost having fights with each other over it.
We desperately need another one.
Do you know of a cheap one?
 :scared:

We have the same fights in production, other departments keep stealing our tester because they broke theirs.

We have a Fluke 1662 type, far cheaper than what your saying. BY high voltage, how high are you wanting?

Without knowing anything else about your scenario, if you need to simply measure insulation would a basic UT513A work? It is a decent insulation meter (I have a UT513 non-A) in the range of a Fluke 1550C - it probably is not as sturdy as the Fluke but it gets the job done.

Oh, the "whys" of the datasheets... The information is there not to be an axiomatic truth, but instead each speck of data must be slowly inhaled while carefully performing a deep search inside oneself to find the true metaphysical sense...

Can you use a megger tester? If so, there are many models that let you select the testing voltage.

They vary in price from very cheap to reasonable.

i have a UT512, i find it to be highly inaccurate. i ended up putting the HV thru a uA meter to get an idea of the "insulation leak". does anybody else also use it in this way like me?
