Answer / katoch

it should be zero volts.but practicaly when we check
voltage b/w nutral and ground it is found near about 1 to 2
volts

Answer / rams dharavath

The voltage between neutral and ground should be less than 5volts

Answer / kalidassallinterview

It should be zero. In power plant and substaton thay
maintain less then 1 ohm of earth resistence. So, to reduce
the voltae drop the neutral and body earth shold be perfect.

it should be 55 volts if you keep isolated secondaries

ASKED.

What size cable (based on voltage drop) is required to supply a 40 A three phase boiler if the wiring system is 75V single insulated cables installed in non-metallic rigid conduit 56m from the main switchboard? Voltage drop in the consumer's mains is 8V.

armature is that part in which current is induced since in dc motor we supply current to the conductor so why we call it armature?

Energy metering: On the property I am renting, the supply voltage is 2 x 110 volts. These 2 x phases enter a energy meter which then exit the meter to over head lines to my house. Question 1. The meter is single phase 240 volts but is being used as 2 x phase(2 x 110volt), is this acceptable? if not, please give me the reasons. The meter details are as follows: 60Hz 15amp Imax 100 amp Kd 3,6 Wh/R 1 fase 3 hilos Model FX 231. I think it was manufactured in Brasil From this meter, the cables run along over head aluminum conductors,I estimate the cross sectional area to be 25mm diameter, but the neutral is only about 10mm square diameter, which cover a distance of 170 meters and then terminate with an underground cable of 65 meter length, total length = 235 meters. There must be a huge voltage drop over this length. This line is protected with 2 x 200 amp aluminum fuses after the meter, there is no main switch in the distribution board. These 2 phases connect directly onto 2 busbars. Surely the neutral should be the same size as the conductors if not more? Question2. What are your thoughts about this installation, should there be better protection, is the neutral too small? During the night, the lights dim then brighten all the time, this cannot be good for my electrical appliances. In my home, I only have a small electric geyser and fridge, my stove works off gas. But when i use other appliances like the washing machine or microwave oven, the light dim. The internal wiring of this house is done with solid hard drawn copper wires and of course, they have to be under rated. I am a retired electrician by trade, but not on the metering and over head mains side, my experience is on the factory maintenance side of things. Your expertise on these matters will be greatly appreciated. Please inform me how to rectify or make any improvements Kind regards, my power bill is very expensive, so I need to know how to bring it lower. Kind regards, Brian
