In the Typical sense its anything 50 volts or below. When speaking of service voltages its 600 volts or below. The threshold of 50 volts is believed to be the point where skin will resist shock so a lessor hazard is encountered. Type your answer here...

A low voltage distribution system is an electrical network that delivers electrical power at a lower voltage, typically below 1000 volts, to various electrical loads such as buildings, residential areas, or industrial facilities. It consists of Transformers, switchgear, distribution panels, and wiring that distribute power from the medium voltage or high voltage grid to the end-users. These systems are designed to ensure a safe and efficient delivery of electricity to different equipment and appliances.

What is a distribution voltage?
An intermediary voltage between high voltage and low voltage. I previously wrote 69kV and 34.5kV were distribution level voltages. This is not true, these are generally considered "sub Transmission" level. Anything below ~ 33kV and above ~1kV is considered distribution. Common voltages of this range I've seen are 2.4kV, 12.5kV, 13.8kV.
What is the Use of distribution transformer?
A transmission transformer steps the voltage up to a very high value so electricity can travel long distances on transmission lines from the power plant to a city or area with low loss. A distribution transformer steps the high voltage back down to a level that can be used for local distribution and use by businesses and homes.
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.
Can you run a double phase motor on home 220 volt system?
If you mean a dual voltage motor 120/240 then yes these will operate on a 240 volt home distribution system.
Can 120v 20w bulb be used in low voltage 12 volt system?
No, it would glow very dimly or not at all. Bulbs must run at the voltage they were designed for.
What is service mains in power transmission system?
A 'service mains' is not associated with an electricity 'transmission' system, but with a low-voltage 'distribution' system. The service mains is the name given to the cable that connects a building to the low-voltage mains supply.
How many volt in low voltage?
There are three main categories of low voltage. It depends on what type of system the voltage belongs to, as each system has a bottom end or low voltage assigned to it.
What is LT system?
LT is Low Tension - it means Low voltage. generally up to 440 Volts system is known as low voltage system
How do you solve low voltage in electricity problems?
low voltage problem may arise due to unbalancing of distribution transformer in your area. please ask your electricity provider to balance load on distribution transformer.
What is the function of transformer 33kv?
A '33-kV transformer' is a three-phase primary-distribution transformer, used in the UK's electricity system to step down the 33-kV primary-distribution voltage to the 11-kV secondary-distribution voltage -the lowest voltage used in the high-voltage distribution system. These transformers are categorised as 'power transformers', and are located in what are termed 'primary substations'.
When connecting low voltage cables to a Secondary Distribution Center where should you start?
At the bottom

How 33kv power converts into 440volts?
33 kV (not 'kv'!) is the standard primary-distribution voltage used in the UK's electricity supply system. Low voltage (400/230 V -not 440 V) is normally provided by transformers supplied from the 11-kV system, not the 33-kV system.
Why is auto transformer is not used as a distribution transformer?
They can be. The benefit of an auto transformer is it can be made smaller than a traditional transformer and have the same power rating - this is because some of the power in an auto is transferred via conduction, while in a traditional transformer all power is transferred via induction.If the voltage ratio between High / low voltage is much above ~3, this size savings is lost. The highest ratio I've seen in an auto is 3.33. Many distribution transformers convert voltage from 30-70kV to 2.4-13.8kV, so for many cases you will end up with a ratio in the 4-10 range, although I have seen some as low as 2.5.Another AnswerAutotransformers are not used in the secondarydistribution system -i.e. they are not used to step down a high-voltage distribution voltage to a low-voltage distribution voltage- for two reasons.Firstly, they do not provide electrical isolation between the high- and low-voltage systems. This is essential, for reasons of safety.Secondly, should a break occur in the low-voltage part of the winding, the whole of the primary voltage will be applied to the load.For this reason, autotransformers are restricted to transmission and (in some cases) primary distribution systems -i.e. they are used as power transformers, rather than as distribution transformers.
How much voltage in phase to phase?
First of all, the correct term is 'line to line', not'phase to phase'. The line to line voltage is called a line voltage, and its value depends on the electrical standards in your country, and the point in the electrical tranmission/distribution system where it is measured. In the UK, for example, its value could be between 400 kV (high-voltage transmission line) and 400 V (low-voltage distribution line).
How do you increase voltage of distribution bus bar?
A hybrid grid mini-system
Can auto transformers be used as distribution transformers?
Yes they could, depending on the design of the distribution system. It's important to note the voltage ratio usually needs to be less than 3 or 4 for an autotransformer to be cheaper than a normal two winding transformer.AnswerAutotransformers are not normally used as distribution transformers, because the low-voltage secondary circuit is not electrically isolated from the high-voltage primary, and this is potentially very hazardous.
