How do you measure the current and voltage in high tension line?

To measure high voltage use suitable instrument transformer (potential transformer)
Very carefully. It can kill you. The higher the voltage the more the danger or arcing over even when two conductors are not touching. Voltage meters are rated and the rating should not be exceeded. Depending on the voltage you will need the proper meter and a high voltage probe rated for the voltage you are measuring. If you don't know what you are doing, don't mess with high voltage. Leave to the pros.

What is the high tension line?
High Tension transformer means (HT) high voltage transformer.
What is the difference between HT and LT line?
ht cable that means voltage level is high , it is obvious that power is going to remain same ,so if voltage rises ,current has to be lowered .since current level is less in ht cable therefore size (dia) is less compared to l.t cable , (p=v.i),lt cable current rating is more and voltage rating is less
What is high voltage motors and low voltage motors?
None: "high tension" is just another way of saying "high voltage".
How do you measure Input high voltage?
You can measure high voltage by using Potential Transformer (PT). or by using utility meter or power manager. ANSWER: Adding a hi resistance in series with a low resistance and measuring that voltage drop. If the resistance is known then current is determined and the source can be calculated. transformers do not work well with DC,
If voltage is increased in a circuit what happens to current series and parallel respectively?
In this case current flows from a high voltage to a lower voltage in a circuit.
What is high tension motor?
High Tension motor is High Voltage Motor.
What is the high tension line?
High Tension transformer means (HT) high voltage transformer.
Why are high tension electricity wires called that?
The high tension does not mean mechanical tension, it means high voltage, generally in the hundreds of KV
An ammeter and voltage range are measure the current and voltage electric lamp if mistake meter interchange what will happen?
1. Voltmeter has high impedance and hence will restrict the current severely.a) Electric Bulb will not glowb) The Ammeter will just measure the current that Voltmeter allows and since this current is much smaller than actual current nothing will happen to ammeter.c) The Voltmeter will measure the Voltage that is being applied.d) This will allow you to measure the resistance of the Voltmeter.VR=V/I

None: "high tension" is just another way of saying "high voltage".
How many voltage will pass through the high tension line?
It depends on the line, but AC high tension lines are typically between 100kV to 750kV while some DC high tension lines are as high a 1MV.Another AnswerVoltage doesn't 'pass through' a line. It appears between, or across, adjacent conductors. It's CURRENT that 'passes through' a line.

ANSWER: Adding a hi resistance in series with a low resistance and measuring that voltage drop. If the resistance is known then current is determined and the source can be calculated. transformers do not work well with DC,
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 spark plug voltage?
Spark plug voltage is high tension voltage, needed to jump a spark between the plus and minus poles. Needed tension is about a minimum of 10.000 Volt between the poles.
What is The operation of Current Transformer?
CT together with a ammeter is used to measure the current in high current or high voltage circuit, where a normal ammeter can not be connected in series in such high voltage or high current circuits. It is a secondary winding (like in transformer) wound on a single core primary wire and relative secondary current reperesnets the primary current. CT are also used protection purposes. Basic principle of CT i same either for metring or protection.
Why high voltage does not kill?
Its not voltage that kills it is current.High voltage CAN kill, if it can also provide high current (especially if the current comes near the heart as it takes under 1mA to stop the heart which isn't much current).However if the high voltage source is current limited and/or the current only passes through the extremities it is very unlikely to kill.
