How ground fault indicator lights work.

[@johntrauger68]

Thanks. Had that system in an old lead smelter in Pennsylvania. Along with the lamps.
Good memories, and essential for our workers to know this.
Still in the business in my 70th year!

Hii sir

[@bravindsouza3375]

I have doubt ... If earth fault comes then ship hull will be at phase potential ?

[@markchiu8667]

Good help. Thanks a lot.

[@izaacridler9234]

Care to elaborate on how a fault to ground doesn’t explode? Or at least cause the o/c device to trip. Or potentially share a video link with an explanation. My teachers tried explaining this to me multiple times & I’m still not getting it

Please if you can consider the effect of ferroresonance on a voltage transformer.

[@AmanKhan-nt3zv]

Thanks Sir.

[@bravindsouza3375]

Sir it means hull comes at the phase potential in case of earth fault ?

[@JarebMendez]

So does the right most leg of the Delta source have a potential of zero across it due to the ground?

[@PILETIZER]

Could you have the same light bulb setup on 600v 3 phase Y?

[@sergioalonso9222]

Is it possible to have a ground detection system on a 1P 2W system??

[@bravindsouza3375]

Ground fault current will not flow ?

Good video :-)

120 volts on the lightbulbs. you did not show the math to change the line voltage 208 to the Why phase/bulb voltage? thank you

120 × √3 = 208
