Distance between ehv lines?
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.
What is the line voltage between two lines?
the voltage between 1 line & phase =120v The voltage between 2 line =240
What is the VSWR and reflection coefficient?
VSWR = voltage standing wave ratio = ratio of the maximum voltage to minimum on a line = VSWR = Emax / Emin = Imax / Imin Reflection Coefficient is the ratio of reflected voltage to incident voltage. = ZL - ZO / ZL + ZO
Why voltage is measured between 2 points?
because voltage is the 'electrical potential difference'. since a "difference" can only be evaluated between two points so is voltage :)
What is the main difference between HT and LT Lines?
It's the voltage: HT high voltage LT low voltage Tension = voltage (French?)
What is the maximum touch voltage in dry conditions?
The maximum level of voltage allowed for a person to be exposed safely.
What is high voltage electrical field?
Two plates with a voltage between them have an electric field in the space between them equal to the voltage divided by the distance. A single sphere at a high voltage has an electric field round it that decreases with distance. High voltage components have a strong electric field round them, and this can be dangerous, so it is usual to specify the maximum acceptable field and set a safe distance for people on that basis.
Voltage drop not exceeding what percent is allowed for feeders?
According to the NEC (national electric code) a maximum of 2% voltage drop is allowed.
What is relation between voltage and conductors?
Your question is unclear. But, if you are asking what the relationship between voltage and the distance between conductors is, then the higher the voltage, the greater the distance must be.
What is the minimum distance allowed between two joints in a high voltage cable of 66 KV?
the minimum distance between two cable joint 2 meter (refer IEC 60052-4)
Distance between ehv lines?
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.
What is the difference between 1n4004 diode and 1n4007 diode?
The main difference between a 1n4004 and a 1n4007 are in the maximum RMS voltage, the maximum DC blocking voltage and the maximum repetitive peak reverse voltage. These are 280 and 700, 400 and 1000, and 400 and 1000 volts respectively.
What is the maximum length allowed on a 20 amp rated branch circuit if is a120 volt single phase?
A maximum distance of 52 feet will limit the voltage drop to 3% or less with a #12 copper conductor delivering 20 amps on a 120 volt system.
What are the rating of MOSFET?
The basic ratings are:ID, the highest average current (and IDmax, the highest peak current) that you are allowed to feed through the drain and source terminals, andVD, the maximum voltage that you are allowed to apply between drain and source.
What is a strong electric field?
THE MAGNITUDE OF ELECTRIC FIELD IS kq/radius-square . IF THE Q[THAT IS CHARGE ] IS BIGGER IN MAGNITUDE OR IF THE DISTANCE BETWEEN THE CHARGE PARTICLE AND POINT CHARGE IS MINIMUM THAN WE CAN SAY THAT IT IS A STRONG ELECTRIC FIELD
Distance maintain between phase to phase?
is there a minimum distance between 480 volt phases. ANOTHER ANSWERThere is no such thing as a 'phase-to-phase' voltage. The correct term is 'line-to-line', which is why that voltage is called a 'line voltage'. The distance between these line conductors depends on the value of the line voltage; the greater the line voltage, the greater this distance must be to prevent any flashover. These distances are specified in the utility company's standards or regulations.
Maximum generating voltage in world?
maximum generated voltage is 21KV
