Internal Arc Performance of Instrument Transformers Filled with Different Dielectric Liquids
EnergiesInternal arc testing is still a controversial topic in the instrument transformer world. The main reason for that is the fact that even a fully successful test guarantees only a certain degree of transformer safety. Furthermore, the test does not cover a

New Directions in Categorical Logic, for Classical, Probabilistic and Quantum Logic [PDF]
, 2014 Intuitionistic logic, in which the double negation law not-not-P = P fails, is dominant in categorical logic, notably in topos theory. This paper follows a different direction in which double negation does hold.
