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.
本文提出了一种使用 PRTG 物联网（IoT）平台开发用于低电压/高电压开关柜的微气候监测的解决方案。这种基于物联网的实时监测系统可以实现预测性维护，从而降低由于环境条件不利而导致电气站故障的风险。湿度和灰尘的结合可能导致沿中低压电桌内的绝缘子发生计划外的电放电。如果不采取预测措施，情况可能会恶化，并导致开关柜内部和外部的重大损坏。因此，这种情况可能会导致未经计划的维护干预，从而导致整个受影响的开关柜发生变化。使用低成本、高效的系统，可以监测开关柜内外的气候条件，并将其远程传输到监控中心。从使用 365 天时间间隔获得的结果可以得出结论，所提出的系统已成功集成到开关柜的维护过程中，从而降低了维护成本。
