  • Publication number: 20150214855
    Abstract: A high powered current generator for electromagnetic inspection of hydrocarbon pipelines from an AC stabilized with rectangular waveform and whose measurements and interpretation are used for evaluating the condition of the lining of the pipelines of five main modules: self-programmable regulated voltage power source module; power source reference decoupling module; H Bridge inverter module; feedback module, and control and processing module. The generator was specifically designed as part of the instrumentation of (TI EMS); which supplies an electric current in the pipeline to produce electromagnetic radiation along the hydrocarbon pipeline. This energy is detected by antennas for obtaining the location of the pipeline and the electric current flowing therein. The generator produces an alternating current at a frequency that can be set within the range of 0.1 Hz to 1 KHz. However, to simplify the job of the operating personnel, default values of 0.1, 0.2, 0.
