Partial Discharge and Internet of Things: A Switchgear Cell Maintenance Application Using Microclimate Sensors

Abstract

This paper proposes a solution for the development of microclimate monitoring for Low Voltage/High Voltage switchgear using the PRTG Internet of Things (IoT) platform. This IoT-based real time monitoring system can enable predictive maintenance to reduce the risk of electrical station malfunctions due to unfavorable environmental conditions. The combination of humidity and dust can lead to unplanned electrical discharges along the isolators inside a low or medium voltage electric table. If no predictive measures are taken, the situation may deteriorate and lead to significant damage inside and outside the switchgear cell. Thus, the mentioned situation can lead to unprogrammed maintenance interventions that can conduct to the change of the entire affected switchgear cell. Using a low-cost and efficient system, the climate conditions inside and outside the switchgear are monitored and transmitted remotely to a monitoring center. From the results obtained using a 365-day time interval, we can conclude that the proposed system is integrated successfully in the switchgear maintaining process, having as result the reduction of maintenance costs.

“…Data collected for microclimate regulation are intended to be accessed by public and organic certification bodies and integrated with Internet-of-things-based real-time monitoring systems based on cloud platforms [92] or edge-distributed computer systems [93].…”

Energy Collector Based on Piezoelectric Nano Materials in the Power Supply System to Improve the Efficiency of Industrial Internet of Things (IIoT) for Industry 4.0

“…When 0 q  , the two roots of Equation ( 18) are real roots and different signs. The singularity at this time is unstable, and the steady state motion of the energy cannot be achieved [22]. When 0 q  and 0 p  , the singularity is stable, and the steady state motion of the energy collector can be achieved.…”

Switchgear Digitalization—Research Path, Status, and Future Work

“…If a full condition monitoring system for switchgear is utilized, such as in [ 45 ], it would yield a reduction of 65% in three-year maintenance tasks, increasing the maintenance cycle by 30% and undoubtedly having a positive impact on cost reduction, and ultimately, ensuring a reliable long term switchgear operation. The safety study of ship power failures [ 46 ], concluded that in many power failures caused by worn or old components, the root sources were actually deficiencies in the maintenance system.…”

“…The implementation of real switchgear operation data will positively impact the overall accuracy of the digital twin, especially in the context of digital twins for ships. Additionally, using effective condition monitoring may reduce maintenance tasks by 65%, saving costs in labor and parts, while also reducing the risk of equipment damage during unnecessary inspections, decreasing failure probability, and optimizing the complete maintenance program [ 45 ].…”
