How do you test an impulse line and why it is necessary?
The voltage is measured by high and low range. Measurements are referred to as r.m.s. , switching impulses reflected by line to line, earth to line contact.
Can you use 240 volts to 220 volts?
Each voltage has a range and devices rated in that range will all work . The 110 to 120 volts is one range of voltages. The 220 to 240 is another range of voltages. The reason there is a range of voltages is to help the utility company out. They are mandated to keep the voltages within a + or - 5% range of a set voltage. Because there are loads coming on line and loads dropping off line the voltage fluctuates. Using a base voltage of 115 and 230 volts means that the voltage can rise by 115 +5% = 121 volts and drop by 115 - 5% = 109 volts. In the 230 volt range the voltage can rise by 230 + 5% = 241 and drop by 230 - 5% = 219 volts. As you see they are still in the usable voltage ranges.
How can you change a 200 volt socket into a 240 volt socket?
You do not need to. Each voltage has a range and devices rated in that range will all work . The 110 to 120 volts is one range of voltages. The 220 to 240 is another range of voltages.

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 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 fluorescent bulbs work?
It is a gas filled container and the gas need a higher volts to initially breakdown for conduction so a starter is necessary to increase the line voltage to higher voltage at the same time a heater is applied at both ends to heat the gas to maintain conduction
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.
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.
