HochspannungsGleichstromübertragung

HochspannungsG... is not a standard or widely used single term in electrical engineering. In German, words beginning with Hochspannung often refer to high-voltage topics or components. This article provides a concise overview of high-voltage concepts and common German terms that might start with Hochspannungs-.

High voltage generally denotes voltages well above ordinary distribution levels. In practice, this means alternating current (AC) voltages above about 1000 volts or direct current (DC) voltages above around 1500 volts. Systems designed for high voltage require specialized insulation, generous clearances and creepage distances, robust enclosure protection, and stringent safety procedures.

Common related terms include Hochspannungsgleichrichter, Hochspannungsgenerator and Hochspannungsgerät. A Hochspannungsgleichrichter is a high-voltage rectifier that converts AC to DC at high voltage, often used to power scientific instruments, accelerators, or HV test equipment. A Hochspannungsgenerator denotes devices that produce high voltages, which can be static or pulsed; architectures include transformer-based supplies, Marx generators, and Cockcroft–Walton multipliers. Hochspannungsgerät refers to high-voltage equipment in general—power-electronic converters, HV test benches, insulation systems, and protective enclosures designed for safe operation at HV levels.

High-voltage networks cover transmission and distribution. In power systems, voltages of 110 kV, 220 kV, or 380–400 kV are common for long-distance transmission, with stepped-down voltage at substations feeding lower-voltage distribution networks. Insulation coordination, insulation testing, and protection schemes are essential to maintain reliability and safety.

Standards and safety: international and regional standards (IEC, CENELEC, and national bodies such as VDE in Germany) govern insulation, clearances, testing, and electrical safety practices for HV equipment and installations. Compliance, risk assessment, and appropriate training are critical in any HV context.
