What do you use to mark the high voltage cable with respect to proper phasing?
exterior plastic tape
Where would you use xlpe cable?
for high voltage more than 11 KV and low current we can use XLPE cable.
What cable to use for light of 540 watts?
Need a voltage to answer this question.
Electrical Properties of Transformers why you use it?
Transformers are used to convert electricity from high voltage to low voltage and from low voltage to high voltage.
Is it okay to use thicker cable to avoid voltage drop?
It is mandatory to use a larger wire size to overcome voltage drop at the load.
What is the difference between high and low current?
The difference between low voltage and high voltage for the same size cable is that cable size affects current carrying capacity, while power is voltage times current. As a result, the same size cable can transfer more power at high voltage than at low voltage. This is why utility power transmission and distribution systems use high voltage. A typical transmission voltage in the US might be 69 kv, 138 kv, even 345 kv, and a typical distribution voltage in the US might by 13.2 kv.
Are low voltage pumps any good?
Sure, as long as you feed them reliable power. Low voltage means they'll need high current to do the job, so you have to use heavy cable and good connections. If you skimp on the power hookup between the battery/generator and the pump ... using cable that's too light or dirty connections, you lose voltage in the cable, and the pump has a hard time doing its job on what you're feeding it.
What does inductive load effect on High Voltage transmission line?
the inductive load which is generally use in high voltage transmission line known as transformer. the transformer transform the high voltage to low voltage.
Can use rectifier in high voltage?
Sure, as long as it's rated for that voltage.
Can a meggar tester be use to measure voltage standing wave ratio in a feeder cable?
No
What is the purpose Sheath Voltage Limiter in high voltage Under groung cabling?
A sheath voltage limiter is an arrester that is used to clamp the voltage induced on the sheath of an underground high or medium voltage cable during a fault on the system. It is common practice when applying underground cable to only ground the cable sheath at one end of the cable, and leave the other end open. Leaving one ungrounded reduces circulating currents and losses during steady state operations. IEEE standard 575-1988 indicates that typically distribution arresters can be used for this function. IEC Application guide 60099-5 soon to be published offers a formula to use to determine the voltage rating of the arrester, but does not offer any guidance regarding the energy handling rating.
What are the advantages of increasing the voltage in a circuit?
For appliances that need a lot of power, the advantage of a higher voltage is that less current is needed, because power = voltage x current. That means that the cable doesn't need to be so thick. It also means that for a given percentage of voltage drop in the cable, the allowable volt-drop in the cable is higher when the supply voltage is higher. This also allows the use of a thinner cable especially when the cable is 100 ft long or more.
