What is high voltage

The term high voltage usually means electrical energy at voltages high enough to inflict harm on living organisms. Equipment and conductors that carry high voltage warrant particular safety requirements and procedures. This is in contrast to an overhead line, which does not have insulation. A high - voltage , direct current (HVDC) electric power transmission system uses direct current for the bulk transmission of electrical power, in contrast with the more common alternating current (AC) systems.

For long-distance transmission, HVDC systems may be less expensive and suffer lower electrical losses.

Technical Issues: Certainly, for most engineers, high voltage is different voltage.

Other variables enter into the design and manufacturing processes.

You need to take into consideration creepage distance , insulation thickness, corona and geometrical arrangement. Some standards do define high voltage . THE MAJOR DIFFERENCES BETWEEN HIGH VOLTAGE SUPPLY AND LOW VOLTAGE SUPPLY ON BOARD SHIPS ARE: Why High Voltage in Ships? High voltage power supplies can operate from DC or AC input voltages. DC input voltages are economical to use in low power applications (watt to 1watts). A Ship cannot run on the traditional electrical systems with less voltage.

The high capacity marine diesel engines and other machinery on ships require higher voltage systems to produce more electrical power. Find out the reasons for using high voltage systems on board ships. While it is always prudent to consider safety regardless of the voltage or amperage, there are specific guidelines that define high voltage (HV) and how one designs for high voltage. So why even worry about high voltage ? This is distinct from the local wiring between high - voltage substations and customers, . For decades, Siemens high - voltage substations have been the reliable nodes of power systems all over the world.

They enable the reliable transmission of large amounts of power. Our technology leadership continues to facilitate developments in areas such as ultra- high - voltage . V-2kV are referred to as “ high voltage ” and voltages 2kV-1kV are referred to as “extra high voltage,” with 1kV also referred to as “ultra high voltage. The emphasis of this guide is on low and medium voltage distribution systems.
