What are the standard voltages for transmission?

The standard voltage for transmission is about 115 to 1,200 kV (long-distance transmission). The extreme high voltages are measured more than 2,000 kV and it is exists between conductor and ground.Answer for UKThe standard transmission voltages in the UK are 400 kV and 275 kV. Primary distribution voltages are 132 kV and 33 kV, and secondary distribution voltages are 11 kV and 400 V. These are all line voltages -i.e. voltages measured between line conductors.

What voltages should never be measured directly with a VOM?

A VOM 'Voltage Meter' measures from a electrical outlet. Any voltage over a 1000 should never be measured directly with it.

High AC voltages are usually measured with?

They are usually measured using potential transformers that lower the voltages so that normal metering equipment can be used. Potential transformers PT's are almost no different that regular transformers except they are designed to be extremely accurate since they are used for metering purposes.


How do you calculate the resultant 3 Phase voltage when each has a different reading close to 230?

Your question is not clear.There is no such thing as a 'resultant' three-phase voltage. There are three, separate, line voltages (i.e. voltages measured between line conductors) for a delta-connected supply, which are equal in magnitude to the corresponding phase voltages. For a balanced wye-connected system, there are three line-voltages (again, measured between line conductors) which are 1.732 larger than the three phase-voltages (measured between each line conductor and the neutral conductor). For an unearthed unbalanced three-phase wye-connected load (unusual, but possible), the figure of 1.732 doesn't apply; instead the relationship must be determined by vector addition.If your question means to ask how do you determine the line voltages of a wye-connected system, given a set of unbalanced phase voltages, then you must vectorially add the relevant phase voltages to determine the relevant line voltage, taking into account the sense, or direction, of each phase voltage.


What is the dimension of displacement?

Radians.Another AnswerIf you are referring to 'angular displacement' in the context of three-phase transformer connections, then it's defined as the angle by which the secondary line voltages lag the primary line voltages, and is measured in (electrical) degrees.

What are the effects on the voltmeter if voltages measured exceed the range?

If the voltage measured exceeds the voltmeter range then the voltmeter needle remains in it's maximum position until it's voltage values are considerably reduced.


Why potential difference at every point in parallel circuit is same?

Kirchof's Law - the voltages are measured between the same starting-point and end-point.


What is the term of null balance?

Null measurements balance voltages so that there is no current flowing through the measuring device and, therefore, no alteration of the circuit being measured.
