6 FAQs about [High-voltage GrounHV Series]

What is a high voltage direct current (HVDC) transmission system?

A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems. Most HVDC links use voltages between 100 kV and 800 kV.

What are the three types of grounding in a high voltage power supply?

There are typically three types of ground in a high voltage power supply system; the input power source, the low voltage control and monitoring circuits, and the high voltage return. These three grounds should have their own independent, dedicated current return paths and should be connected using a “star” grounding technique.

What happens if a high voltage system shares a ground?

Many high voltage systems require extreme accuracy, if the programming signal shares a ground with a power ground an error will be introduced. There are typically three types of ground in a high voltage power supply system; the input power source, the low voltage control and monitoring circuits, and the high voltage return.

What is a UHVDC supergrid?

UHVDC is defined as DC voltage transmission of above 800 kV (HVDC is generally just 100 to 800 kV). One of the problems with current UHVDC supergrids is that – although less than AC transmission or DC transmission at lower voltages – they still suffer from power loss as the length is extended.

Why is the output ground a problem in high voltage systems?

The output ground can be especially problematic in high voltage systems. Stored energy (measured in Joules) equals ½ CV squared (Capacitance and Voltage) meaning that energy transferred during a high voltage discharge rises very quickly with increases in voltage.

Does a high voltage power supply need a ground path?

In truth, there is no ideal ground, all ground paths have inductance, resistance and noise. Managing the various ground paths interfacing with a high voltage power supply makes the difference between a good design and a great design. With high voltage power supplies, ground path issues become increasingly problematic as the voltage increases.
