In neutrino physics, most of the experimental data importants can be explained due to neutrino oscilation induced by mass and mixing. However, there is the posibility that the neutrinos have some properties, new physics or beyond Standard Model. This new physics can be explained with some so far unknown exotic particles that are responsables for extra interactions ornon standard interaction with neutrinos and here we studied fenomenologically, without concerning about any theoretical model. In this Thesis, we study the effects of Non Standard Interaction (NSI) with matter in experimentsof oscilation in long baseline. We consider two identical detectors, but wih diferent baselines from source, in two cases: first, we study the probing potencial to analyse the NSI effect for experiments that use conventionalneutrino beams coming from pions decay. For example, we should consider a neutrino beam created at the Proton Accelerator JPARC (Japan Proton Accelerator Research Complex) in Japan. We consider two detectors, in additionto the front detector at JPARC to monitor the beam; we have the first in Kamioka, Japan and other somewhere in Korea, the first is at 295km, and the second is localizate about 1000 km from JPARC. In sequence, we also evaluate the potencial of Neutrino Factory, where a neutrino beam come from a muon decay storage ring, in order to study the non standard interactions parameter and its impact in CP phase sensibility and the mixingangle 013. In this work we combined theses simulated data from two detectors with differents baselines, with the first localized at 3000 km and the other at 7000 km from the source. The baseline of this second detectorwas chosen because it has a special feature, the Magic Baseline, where theoscilation probability do not depend of CP phase violation when the nonstandard parameters are absent.
