Electrical Safety & Function Tester. V. 154.

Zoomup
I have just obtained a Clare V.154 "P.A.T" tester.


It has a flash test facility at 3000V or 4000V and a large test probe that looks like a 50s sci-fi film ray gun. I will thoroughly service the instrument before use, and am not inclined to use the flash test facility, but am curious about how it produces the high Voltages. I have not opened the instrument yet so it will be a treat to have a look inside. Circa 1984 I believe.

    By mains transformer and rectification - no need for clever inverters when 50Hz is available. The voltage is not that inconvenient, I'd expect a voltage multiplier rectifier to keep the winding efforts reasonable - Cockroft and Walton  style. Maybe not as big as the ones in the photos on that page.
