What is typical line voltage tolerances?
Tolerances are about +/- 5 percent. Scroll down to related links and look at "List of countries with mains power_plugs, voltages and frequencies - Wikipedia".
Does voltage vs current graph passes through origin?
Yes. While it isn't clear what device you are talking about, and different devices have different characteristic curves (for example, a straight line for a resistor), a voltage is required for a current to flow, so if there is no voltage, there won't be any current, either.
Why Base Transceiver Station equipments require negative 48 volt DC to function properly why not positive?
it has two reasons.one is to prevent corosion due to the elecrtolitic effect and the other is to protect operator from the line voltage.. it has two reasons.one is to prevent corosion due to the elecrtolitic effect and the other is to protect operator from the line voltage..
What is a temperature line?
a temperature line is a line of temperature
How warm should air be out of heating ducts?
That would depend on a number of things, including the size of your furnace and heat loss rate and size of your home. Example: I replaced a 100,000 btu furnace with a 50,000 btu to heat my 1200 sq ft home. Both do/did the job but the 50,000 is more correctly sized and thus runs longer and cycles less. The 100,000 on the other hand was oversized, cycled more often for shorter periods and as you can imagine the air out of the ducts was warmer than with the 50,000. Bottom line,the proper sized furnace correctly installed will do the job better with less wear and tear on the equipment than an oversized unit. Though the oversized unit will give you warmer temps at the duct outlets. To see if you can raise your duct outlet temps, have a contractor perform a heat rise test on your furnace and if there is room to do so he may be able to give you warmer air temps by slowing down the fan. Be aware, all furnaces have a maximum heat rise rating set by the mfr and this cannot be exceeded, But if by chance you are moving too much air in the heat mode there may be room to slow it down without compromising the life span of the equipment.
How the voltage regulation in 33kv line?
It does not depend on the line. The regulation is the percentage change in voltage caused by applying the full load current, and that depends on the transformer supplying the line. A value of 5% would be typical.
Is transmission voltage a phase to phase voltage or a phase to ground voltage?
Phase to Phase voltageCorrection to the above answer:There is no such thing as a 'phase-to-phase' or 'phase-to-ground' voltage. The correct terms are 'line-to-line' (or 'line voltage') and 'line-to-ground' (or 'phase voltage'). Transmission-line voltages are line-to-line (or 'line') voltages.
What is a condensate line in a furnace?
its the drain line for water to drain
What is the typical line voltage for gas furnaces?
For the internal fan operation, 110v AC is the standard. For thermostat control, usually low voltage, like 12 or 14 v DC.
What is edge speed in electronics?
A voltage is applied to a signal line. The voltage of the line changes gradually from 0 to +V. The "edge speed" is the rate of change of voltage of the line. A voltage is applied to a signal line. The voltage of the line changes gradually from 0 to +V. The "edge speed" is the rate of change of voltage of the line.
How do you convert 3 phase RMS line-line voltage to RMS line-neutral voltage on an unbalance system Basically how do you calculate using trig for all 3 phase?
The term, 'unbalanced system' refers to an unbalanced load. Under normal circumstances, an unbalanced load leads to unbalanced line currents. The line voltages are determined by the supply and remain symmetrical, even when the load is unbalanced. As your question refers to a 'line to neutral' voltage (i.e. a phase voltage), you must be referring to a star (wye) connected load, in which case the phase voltage (line to neutral voltage) is 0.577 (the reciprocal of the square-root of 3) times the line voltage (line to line voltage).
Is 220V line voltage or phase voltage?
Phase, if you are referring to line, as power line from pole.
What is the line voltage between two lines?
the voltage between 1 line & phase =120v The voltage between 2 line =240
What is a line to line voltage?
In a 3 phase system, the voltage measured between any two phase is called line to line voltage.And the voltage measured between line to neutral is called phase to neutral (line to neutral) voltage.AnswerThere is no such thing as a 'phase-to-phase' or a 'phase-to-neutral' voltage. The correct terms are 'line-to-line' and 'line-to-neutral'.The voltage between any two line conductors is called a line voltage.In a three-phase, three-wire, system, the line voltage is numerically equal to the phase voltage.In a three-phase, four-wire, system, the voltage between any line conductor and the neutral conductor is called a phase voltage. The line voltage is 1.732 times larger than the phase voltage.
What furnace is 98 percent efficient?
Lennox top o the line furnace is 98.2 percent efficient
How match 2 phase line voltage between them?
To match 2 phase line voltage it has to be the same voltage.
What is line regulation?
Line regulation is a measure of the ability of the power supply to maintain its output voltage given changes in the input line voltage. Line regulation is expressed as percent of change in the output voltage relative to the change in the input line voltage.
