Abstract

The present invention relates to a system, a sensor and an electronic circuit with application in the field of devices for measuring low alternating currents, with the aim of monitoring electrical equipment in power substations and assisting in the performance of preventive maintenance, which is essential for ensuring the proper operation and safety of electrical systems. The system comprises a current transformer (1), a measurement module (2), a microprocessor unit (3) and a housing (4). The assembly in question operates in a comprehensive and self-sufficient manner in measuring low currents in power substations. Its operation, based on the magnetic principle, is robust and preserves the integrity of the network by means of contactless measurement from the current transformer (1). The housing (4) protects sensitive components from inclement weather and electromagnetic interference. The direct measurement method developed reduces uncertainties in the system and allows calibration and self-equalisation of the signal by means of simple adjustments made to the measurement module (2), without the need for post-processing to recover the information measured. The data acquired are processed and sent by the microprocessor unit (3) to the server, which provides binary-type files that can be viewed using any available source code editor.

Abstract

The present invention pertains to the fields of geology and geophysics, is designed for use for onshore seismic acquisition. The method involves distributing and arranging the elements used in the acquisition of two-dimensional seismic data from dynamite sources, enabling imaging quality to be improved. The use of sources of dynamite with single charges and variable weight at each shot point results in the generation of seismic waves with variable energy that provide reflections with complementary frequency and amplitudes content for use in the geophysical imaging of geological features. The stacking of this incremental content generated by charges of variable weights results in a significant improvement in the resolution of the processed seismic data on both the continuity of stratigraphic reflectors and existing geological framework.

Abstract

The present invention pertains to the fields of geology and geophysics, and is designed for use in land seismic acquisition. The method involves distributing and arranging the elements used in the acquisition of two-dimensional seismic data from explosive sources, enabling imaging quality to be improved. The use of sources of dynamite with single charges and variable mass at each firing point results in the generation of seismic waves with variable energy that provide reflections with complementary frequency spectrums and amplitudes for use in the geophysical imaging of geological features. The stacking of this incremental content generated by sources of variable mass results in a significant improvement in the resolution of the processed data on both the continuity of stratigraphic reflectors and on existing geological discontinuities.
