Magazine | Issue 1 2023 fleet of generators. In addition, it can be easily integrated into existing monitoring and SCADA systems. The system allows users to configure settings and view data from a remote location using the system’s convenient web interface. Users can set thresholds of tolerable PD levels and receive automatic warnings and alarms when these thresholds have been exceeded so that they can investigate the situation in a timely manner. Convenient software features, such as 3PARD and cluster separation, help users easily separate PD signals from external noise to identify the exact phase indicating a problem. In addition, the pattern classification software feature gives users an indication of the defect type, so they can quickly figure out what’s going on and decide the next steps. Overall, we found the MONGEMO solution to be a very high-end PD monitoring and trending system that ensures users can make informed decisions based on the condition of their rotating machines. The system continuously collects and processes the measured data using expert software features, producing understandable results for users. Based on these strengths, it was easy to convince our customer that the MONGEMO system was their best choice compared to other monitoring systems. Our customer appreciated how MONGEMO could meet their continuous PD monitoring system specifications. It provided them with the information they could base their decisions on for maintenance and eventual replacement without needing a PD expert to review and interpret the collected data. Please describe the installation process at the customer’s site. We installed and commissioned the MONGEMO system ourselves, initially on nine generators located at one of the customer’s refineries. Since we already have a lot of experience with PD and monitoring in general, all we needed were system specifics for installation and commissioning, which we received from the OMICRON team in a training session. They also offered us support via video conference when needed. We previously installed PD couplers while the generators were out of operation for planned maintenance. The MONGEMO four-channel data acquisition unit was installed near each of the generators and is housed in an IP65-compliant protective enclosure to protect it from moisture and typical harsh conditions onsite. The computer used for storage and post-processing of the PD data was installed nearby for easy access to each location. The MONGEMO system was also easily integrated into the customer’s condition monitoring system to assess their generators’ overall performance and safety. Continuous PD trending by the MONGEMO system is a key component in the customer’s condition monitoring system. «The MONGEMO system enables our customer to ensure the reliability of their generators, extend their service life and avoid unforeseen outages.» Mohamed Helmy Halim, Manager, MHH Condition Monitoring Sdn.
