Description
Summary:A mobile electromagnetic environment (EME) monitoring system for electric substations is presented that has been designed to register in real time the levels of electromagnetic interference that can degrade the quality of operating technical means, the purpose of this being to identify systematic disturbances of electromagnetic compatibility and establish the causes of these disturbances. Such interference includes impulse noise arising from lightning strikes, short circuits, and primary equipment switching; overvoltage affecting secondary equipment circuits; fails dips and interruptions in power supply of operating 0.4-kV auxiliary ac/dc systems; and magnetic fields in rooms with technological control systems. The system architecture allows it to be quickly transported and deployed at existing electric substations, which are of the most interest in terms of the EME control. The key functions of the monitoring system are implemented using digital EME recorders and tapped primary measuring data transducers (sensors). The recorder is a digital multichannel oscilloscope equipped with a measuring data solid-state drive and a wireless interface providing access to this data from a master computer. The monitoring system will prevent major accidents at power facilities due to the timely detection of EME deterioration and elimination of EMC violations, as well as collect objective evidence to analyze their triggers.
