Nitrogen Capacitors: a false belief, now revealed!

The use of Nitrogen as capacitor filler continues to be advertised by some manufacturers, even though performance guarantees without any foundation. Therefore, COMAR ACADEMY publishes two Insights on the topic, to shed light on a technology that, although cheaper, does not provide any technical advantage, unlike oil (or resin). COMAR uses ecological vegetable oil that, while respecting the environment, prevents the creation of electric arcs inside the capacitor, penetrating the wire breakpoint if the overpressure disconnector has intervened.
