What are the difference between high voltage and low voltage?

Hi, The main difference is Fuel consumption. High current genertors always consumes much fuel because the load on the engine will be high. The high voltage low current generators doesn't need much fuel to run. You can understand this by comparing 1 kva and 5 kva single phase generators. For both generators voltage will be same (230v) But output current differs. So the fuel consumption also differs. But you get a high current source. Low voltage high current generators can be used for welding kind of stuffs which needs high current to do the job. If you have step down transformer then you can save the fuel.

∙ 14y agoMedium voltage is typically the voltage going from the substations to the service drops. One typical distribution voltage in the US is 13.2 Kv. (That voltage is dropped by the distribution transformer to a low voltage, typically 12/240 split phase or 480 three phase.)
High voltage is typically the voltage going from substation to substation. One typical transmission voltage in the US is 138 Kv.

∙ 10y agoVoltage levels are defined by the electrical regulations in the country in which you live. In some countries, 'medium voltage' is not defined at all. For example, BS7671:2008 Requirements for Electrical Installations, the UK's wiring regulations define voltage levels as 'extra-low', 'low', and 'high' -no mention at all of 'medium voltage'.
According to BS7671:2008, 'extra-low voltage' is defined as 'that not exceeding 50 V rms'; 'low voltage' is defined as that 'exceeding extra-low voltage but not exceeding 1000 V rms'; 'high voltage' is defined as 'normally exceeding low voltage. Different values are given for d.c. voltages.

What is the difference between switchgear and switch yard?
we use switchgear for low voltage while switchyard is use for highvoltage transmission and distribution . There is an other factor known as insulation because for low voltage we should low insulation and for high voltage we need higher insulation.Cost is another factor between both.

How you understand which side of a transformer is high voltage side and low voltage side?
at high voltage side, current is low. hence the size of conductors is reduced or small. At low voltage side, current is high. Hence the size of conductors is large.
Lap winding and wave winding?
Both lap winding and wave winding are found in the use of DC generators. The main difference is as follows: lap winding is high current, low voltage, and wave winding is low current, high voltage.
What is classed as high voltage in the UK?
>1000V rms ACAnswerAccording to BS 7671:2008 Requirements for Electrical Installations, 'high voltage' is formally defined as that 'normally exceeding low voltage', where 'low voltage' is defined as "...(nominal voltages) exceeding extra-low voltage but not exceeding 1000 V a.c. (root mean square) or 1500 V d.c. between conductors, or 600 V a.c. (root mean square) or 900 V d.c. between conductors and earth".
What is the different between domestic and industrial electricity supply?
Electricity for industries are supplied with high voltage.Domestic supply is with low voltage.
What is the difference between LVD and HVD?
Lvd: low voltage differential Hvd: High voltage " signalling techniques
What is the main difference between HT and LT Lines?
It's the voltage: HT high voltage LT low voltage Tension = voltage (French?)
Difference between linear IC and Digital IC?
In linear IC'S the output voltage is very according to input voltage In digital IC's the output voltage is either high or low
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.
