What is the voltage threshold for causing dielectric breakdown in air?
1 Answer
The voltage threshold for causing dielectric breakdown in air, also known as the breakdown voltage or sparkover voltage, can vary depending on factors such as air pressure, humidity, and electrode geometry. However, as a general guideline, at standard atmospheric conditions (around 1 atmosphere pressure and 25°C), the breakdown voltage for air is approximately 3 million volts per meter (3 MV/m) or 30 kV per centimeter (30 kV/cm).
Keep in mind that this is a rough estimate and actual breakdown voltages can be influenced by local conditions and other factors. Additionally, high voltage applications require careful consideration of safety measures to prevent electrical discharge and sparking.
