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 low voltage distribution system?
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.
How much does amperage drop with distance?
It is dependant on the voltage being used, size of wire, distance of the run from the distribution and load connected at the other end.
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.
Define recovery voltage in circuit breakers?
It is the transient voltage that appears across the contacts of the circuit breaker at or near the zero current instant during arcing period. A high frequency transient voltage appears across the contacts and is caused by the rapid distribution of energy between the magnetic & electric field associated with the station & transmission lines of the system at the zero current. This transient voltage is known as restriking voltage.
What is AM voltage distribution?
Amplitude Modulation voltage
How can voltage drop in radial distribution be minimized?
Voltage drop can be minimized in a radial distribution by increasing the cross-sectional area of the conductors.
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'.
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.
How is one secondary distribution center connected to another secondary distribution center?
high voltage cable with loadbreak elbows
How many high voltage outputs does a secondary distribution center have?
2
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 difference between primary electrical distribution and secondary distribution?
Primary electrical distribution carries medium voltage power to distribution transformers near the customers. Secondary electrical distribution transfers the power from the transformer to the households.
How do you increase voltage of distribution bus bar?
A hybrid grid mini-system
What is the electrical function of the secondary distribution centre?
An electrical distribution centre is used to distribute circuits through out the building that it supplies. An electrical panel in your home is classified as an electrical distribution panel. The electrical distribution panels come in varying sizes and voltage ratings depending on what the building requirements are. Amperages for different loads are supplied through breakers that are part of the distribution panel.
What do substations reduce the voltage for?
A: Substations step down the transmission voltage for distribution for the local area. The reason being that their input is in the range 0f 475 Kv trying to distribute that kind of hi voltage would be totally impractical because of insulation. So a substation step down the hi voltage to a distribution level of 16kv or so.
What is difference between nominal and terminal voltage?
The rated voltage of a motor listed on the nameplate is called the terminal voltage. This indicates the actual voltage on the motors terminals at which at which the manufacturer designed to operate. Whereas, Nominal voltage is the design or configuration voltage of the electricity distribution system.
