Arc Voltage Characteristics in Ultrahigh-Pressure Nitrogen Including Supercritical Region

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1528706

A supercritical (SC) fluid is formed when both pressure and temperature of a fluid exceed the critical point, where distinct gas and liquid phases no longer exist. SC fluids demonstrate combined properties of gas and liquid, which make them interesting to investigate them as an arc extinction medium...

Contact and nozzle wear from 100 interruptions for a puffer-type air load break switch

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1475813

One type test requirement for medium voltage load break switches is to interrupt 100 consecutive "mainly active loads". A puffer-type switch with axial-blown arc has been tested according to the 630 A/24 kV ratings. The nozzle and contact wear were measured regularly to investigate design requiremen...

Empirical Relationships between Air-Load Break Switch Parameters and Interrupting Performance

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1251486

A simple gas blow switch consisting of an axisymmetric tulip/pin contact and a cylindrical polytetrafluoroethylene (PTFE) nozzle has been used for empirical studies of medium voltage load current interruption in air. Only the thermal phase of the interruption is considered. Based on the results of m...
