If they don't touch ground, they can take as much volts as they want.Unless they get too close to ground, but the conductivity of the air is variable depending upon weather conditions. (moisture etc)
It's all about conductivity Vs resistance.

ahh but the pole is grounded thus if they get close to that or betweentwo wires on a different phase angle, zap in the case shown the bird seems to be too far away to have been zapped but its possible for a bird to fry itself on some wires.

No, the pole is insulated.. the current is carried across it.(not through it)

insulated byInsulator This black "knob" is a ceramic or plastic insulator. This is the piece that prevents the pole itself from becoming electrified and allows the current to pass through without resistance.
but if a bird joins the pole and the wire its no longer insulated.
the pole is grounded even without any electricity flowing. I mean i could stick a pole in the ground thats not hooked up to anything its going to be grounded. at least thats what im thinking, I think

The bird was no where NEAR the insulatorWasn't it?.. it was on the wire (as in the adage)

B bbbbbut shurely...There would be potential difference between the two feet and a If the If a bird stood with it's legs far enough apart then a proportion of the current would flow through the bird.
The amount would depend on the relative resistance of bird and wire. Obviously the wire is less resistant so most would stay in the wire, but a fraction would go up one leg and down the other.
So... how far apart would it's legs have to be to generate zappable amounts?
That's right innit?

It's not grounded at all..This entire thread is fictional.
Which should not detract from the original beauty of the slop work!
(said bird could spread it's legs across MILES of wire, if it is still not grounded to earth, no shorting effect)

HmmmOk, on a wire... if you put a meter across a section of wire with a current going through it, you will indeed get a potential difference regardless of grounding. Cos wires aren't superconducting.
That's what I learned at skool =)

When currents are involvedThen you can start the math for the incidence of lethality
I hope you are more learned than me as you are hopefully the future.. any hoo, my bed calleth, g'night :)

there is a minimum current for conductivityand bird vs steel your more likely to get a current excited in the birds (magneticaly premiable) body resulting from the magnetic field surrounding the cable, than from the diference in distance of its legs on the wire when it lands.

unless you have a very slaggy bird who has legs that are miles apartuhmm and are very wet with some kind of juices

hmmResistivity = 11.8 × 10-6 Ωcm" for steel at 0c
resitance of a dead chicken (Frozen) over the aproximate distance of a starling groin = thats not really fair i mean its forzen and full of water. im going to have to put an ohmeter over a birds groin while its still alive to find out. this is how scientology wins so many arguments. its because people just cant be bothered to refute such atupid claims. Im going to make myself a gin and orange and sulk. and let you win the argument i was having with myself.

EGGSACLY!So, the question remains, how far apart would a birds legs have to be before it got zapped!
