Where the system voltage is high enough, an electric arc may form between power system conductors and ground.
Low Distribution (system voltage) is covered by 250.20(A) of this code.
A system voltage of 160 V DC is used for the main power distribution throughout the station.
However, because third rail systems present electric shock hazards located close to the ground, higher system voltages (above 1,500 V) are not considered safe.
Further tweaking on other system voltages could doubtlessly have cut the rate further.
Virtual instrument dials on the display show time, electrical system voltage, the road's slope and the compass heading.
The voltage magnitude must be the same as the system voltage.
When the voltage at the generator is opposite to the system voltage (either ahead or behind in phase), the lamps will be bright.
When the voltage at the generator matches the system voltage, the lights will be dark.
It is mainly aimed at providing a reliable estimate of the system voltages.
