Home made VLF? or DC Megger?
(OP)
Hey,
I am currently looking into creating a tesla coil, and now that i have gotten started, i would rather build a VLF test set, since they are quite rare around here.
Was wondering if anyone here new if you could make a vlf test set with a high voltage transformer, operating with regualr 120vac, 15A.
and to measure the low frequency and display output with an osciloscope i presume?
I could calculate how the vlf could input a specific chosen voltage from a variac, and measure the current produced, to give me the capacitance, and resistance value of a high voltage cable.
anyone have any ideas on building one of these? i have used them many times before, but regret not taking it apart as it is going to be a fun project to make.
any help on builidng any part of a vlf would be greatly appreciated.

Some design parameters you will need up front are your intended voltage (peak) and load (capacitance). I can not stress the safety aspects enough.

I especially like the truck.

I cannot beleive that how expensive a VLF test set is! I rented one and used a few times, and would like to purchase one now, but at 32 000$, i find it would be fun project to make one. but alot more complex than a tesla coil.
Thanks for the info! any more anyone?
