Validação laboratorial do dispositivo descarregador em forma de chifre para isolação de cabos para-raios em linhas de transmissão

open access: yes, 2020
The use of ground wire for insulated spokes is an alternative to reduce the induced currents existing in cables with multiple grounds. In order for this method to be applied, it is necessary to use horns coupled to the electrical insulators, isolating ...

Eletrodos quimicamente modificados aplicados à eletroanálise: uma breve abordagem

open access: yes, 1997
Chemically modified electrodes (CMEs) have been subject of considerable attention since its inception about 23 years ago. CMEs result of a deliberate immobilization of a modifier agent onto the electrode surface obtained through chemical reactions ...
