# What kV are distribution lines?

## What kV are distribution lines?

Typically, 34.5 kv to 69 kv, this power is sent to regional distribution substations. Sometimes the subtransmission voltage is tapped along the way for use in industrial or large commercial operations. Some utilities categorize these as transmission lines.

## What is normal operating voltage of primary distribution?

Primary distribution voltages range from 4 kV to 35 kV phase-to-phase (2.4 kV to 20 kV phase-to-neutral) Only large consumers are fed directly from distribution voltages; most utility customers are connected to a transformer, which reduces the distribution voltage to the low voltage “utilization voltage”, “supply …

What are the standard transmission and distribution voltages?

Electrical Transmission and Distribution Systems That network consists of electrical distribution substations which step-down the transmission line voltage levels between 69 kV and 765 kV to distribution voltage levels, usually 35 kV or less. Typical distribution voltages range from 34,500Y/19,920 V to 4,160Y/2400 V.

### Which is the voltage range of secondary distribution in kV?

Detailed Solution

Power carrying system Voltage level
Primary transmission 66 kV, 132 kV, 220 kV or 400 kV
Secondary transmission 33 kV
Primary distribution 11 kV
Secondary distribution 400 V

### Is 34.5 kV high voltage?

Higher voltage equipment costs more – cables, insulators, transformers, arresters, cutouts, and so on. But higher voltage circuits can use smaller conductors….Table 1 – Power Supplied by Each Distribution Voltage for a Current of 400 A.

System Voltage (kV) Total Power (MVA)
22.9 15.9
34.5 23.9

How many kV is high voltage?

In the United States, the American National Standards Institute (ANSI) establishes nominal voltage ratings for 60 Hz electric power systems over 100 V. Specifically, ANSI C84. 1-2020 defines high voltage as 115 kV to 230 kV, extra-high voltage as 345 kV to 765 kV, and ultra-high voltage as 1,100 kV.

#### Is 13.8 kV high voltage?

If the distances from the main utility substation of the campus to the individual buildings are great, higher voltages could be used, but the 13.8-kV distribution system is very common. Other common voltages are 12.47 kV, 24 kV, and 24.9 kV (nominally 25 kV).
