Gauge Pressure
The amount of pressure is expressed in terms of atmospheric pressure. It is referred to as “positive pressure” when it is greater than atmospheric pressure, and “negative pressure” when it is less than atmospheric pressure.

Generation Mix
The generation mix is a term used to describe the contribution of various sources of electricity make to the power supply serving a particular region or population. The portion of renewable energy in the global generation mix is rising in response to concern over climate change and increasing demand for electrical power.

Harmonics
Generally, harmonics are oscillations in the base power frequency. In electrical AC systems, the base frequency is typically 50 or 60 hertz (Hz) and harmonics occur in multiples of this, for example, 100 Hz, 150 Hz, 200 Hz, etc. where the base frequency is 50 Hz. Harmonics occur whenever there is a disturbance of the voltage or current, e.g., if the current is interrupted or if AC current is synthesized in a converter. The problem with harmonics is that electrical devices may react differently when exposed to a different frequency than the one they are designed for, which may cause damage. Harmonics are an increasing problem in power systems as most power electronics solutions cause harmonics. Harmonics can be reduced by the use of power filters.
