2019-9-17The leak-rate test (MAC test):This test is based on the Penning Discharge Principle which is named after Frans Michael Penning (1894-1953). Penning showed that when a high voltage is applied to open contacts in a gas and the contact structure is surrounded with a magnetic field, the amount of current flow between the plates is a function of the gas pressure, the applied voltage…
[email protected]High Voltage Switchgear Circuit breakers are needed to ensure that our energy supply systems run smoothly. Until now, they’ve used gases that are much more harmful to the climate than CO2. Sylvio Kosse and Paul Gregor Nikolic at Siemens Energy are working on a way to use pure air in place of these gases.
