Where are you checking the wires at? The service panel or at the outlet? If you're checking at the outlet, it looks like some bad wiring somewhere. If you're reading this at the service panel, then the main entrance wires are faulty (or your electric company is faulty). If the outlet is unloaded you have a resistive neutral. Call an electrician now, if you value your electronics.
Let's get the terminology correct. A 'phase voltage' is measured across a phase, whereas a line voltage is measured between two lines. So there is no such thing as a 'phase to phase' voltage -it's a line to line voltage (hence the term 'line voltage').
120 volt to ground---208 across 2 lines
Similar to the third wire on an RTD, 2 terminals are the current carrying conductors, 2 for the voltage. There will be a voltage drop across any current carrying connection. The voltage sense lines don't carry any current, so they accruately measure the voltage across the calibrated resistor/shunt.
Presumably, you are asking what happens when a conductor 'cuts' lines of magnetic flux? If so, then a voltage is induced across the ends of that conductor.
A line of cells across a spreadsheet is called a row.
The distance between high voltage lines is governed by either a switching impulse voltage or lightning impulse voltage. The distance between lines, or lines and tower must have a high enough dielectric strength to avoid flashover at these voltage. Air can withstand a voltage of 3kv/mm.
It is the transient voltage that appears across the contacts of the circuit breaker at or near the zero current instant during arcing period. A high frequency transient voltage appears across the contacts and is caused by the rapid distribution of energy between the magnetic & electric field associated with the station & transmission lines of the system at the zero current. This transient voltage is known as restriking voltage.
The voltage in the middle of line and impartial is known as the stage voltage. where the voltage between two lines called the line voltage.
The grid lines separate individual cells.
The generation of Arc in high voltage lines takes place whenever the voltage is enough to allow current to jump across conductors by breakdown of insulator. Arcing mainly occurs when the insulation properties of insulators are permanently damaged resulting in complete system failure
Latitude lines go -------- (across) And Longitude goes | | | (up & down)
Increase the voltage in the lines.
No, lines of longitude run north-south across the globe. Lines of latitude run east-west across the globe.
It's the voltage: HT high voltage LT low voltage Tension = voltage (French?)
The hazards in high voltage power lines are most commonly death, but other affects can also take place.
EHV lines are type of electrical lines commonly used for experimentation in physics. They stand for 'Extra High Voltage' lines.
They can. The current in each "line" (correctly, *branch*) depends on (i) the applied voltage and (ii) the individual resistance in each branch. If the branch resistances are different, the branch currents will be different. Ohm's Law will let you calculate the individual currents.
With increased voltage the line requires better insulation. The abbreviations, 'HT' and 'LT', stand for 'high tension' and 'low tension', respectively. In this context, 'tension' is a rather old-fashioned term, meaning 'voltage'. So, high-voltage transmission and distribution lines were termed 'high tension' lines, whereas low-voltage distribution lines were termed 'low-tension' lines. In the UK, 'high tension/voltage' lines are rated at line voltages of 11 kV, 33 kV, 132 kV, 275 kV, and 400 kV, whereas 'low tension/voltage' lines are rated at 400 V line-to-line (line voltage) and 230 V line-to-neutral (phase voltage).
Well, if you look at some different maps, some will have lines that make a grid across the whole thing. The individual lines will be numbered. If you take your coordinates and match them up to the numbered lines you will be able to find where these lines meet up. Where the lines meet is the location identified by the coordinates.
the voltage between 1 line & phase =120v The voltage between 2 line =240
Longitude lines are the lines going vertically across the earth, east and west of the Prime Meridian. Latitude lines are the lines going horizontally across the earth, north and south of the equator.
Yes usually it would be phase to phase voltage because most transmission lines are set up in a delta configuration. This means that there is no neutral conductor to use as a reference. So any voltage would be measured with reference to another phase.CommentLet's get the terminology correct. The voltages between the three 'hot' lines of a three-phase, three- or four-wire, system are called 'line voltages' even though, in the case of a delta-connected system, they are numerically-equal to the corresponding phase voltages. Therefore, we call the conductors 'line conductors', not 'phase conductors'.There is simply no such thing as a 'phase-to-phase' voltage. Just think about it; you can only measure a voltage acrossan individual phase, so how can you possible measure a voltage 'phase-to-phase' -I mean, where would you place a voltmeter to do that?For a delta system, the line voltage (or line-to-line) voltage is numerically equal to the phase voltage (notphase-to-phase). For a star (or 'wye') system, the line voltage is equal to 1.73 x the phase voltage.
