How can we get a Neutral from a three phase suply? If we meet all three phases at a point to take neutral then why dont thay get sparked?

1 2768hi, in the event earth grounding is not available in a project, is there any other way to make the elcb work? fyi, i have an instant water heater (6.5kw) installed, however if there is grounding in the heating element inside the heater assembly, i will get grounded. thank you in advance to those who will answer my question.
1962I FINISHED MY B.TECH IN EEE . I AM IN NEED OF A GOOD TRAINING INSTITUTE TO DO COURSES .. CAN ANYONE SUGGEST GOOD CENTRES IN TAMILNADU ,BANGALORE ,OTHER AREAS???????
1961bit confused - am i correct in thinking that to determine line to line voltage in a star config 110v 3 phase 4 wire distribution system i would use a voltmeter? I have a circuit configured as an unbalanced load, consisting of three incandescent lamps (1x40w, 1x60w, 1x100w - all 110v rated)connected in a star configuration to a 110v 3 phase 4 wire distribution system. I want to find out what types of meters i would use to obtain: a) each line to line voltage b) the line to neutral voltage across each load c) current flowing in each line and load d) current flowing in the neutral conductor e) power supplied to the loads im assuming i would be using ammeters in series along each line and voltmeters in parallel across each line to neutral? Also how could i predict these meter readings before taking them and with which formulae? Any help would be greatly appreciated A.
1 3205I need to compare the energy consumption of an industrial machine before and after improving. Shall I compare the apparent power or the active power? I know usually factories use compensated capacitors (or other similar components) to compensate the reactive power, so if I use the apparent power, it's not the real power consumed.
