NOJA Power Switchgear provided a practical demonstration during a recloser training session to the engineering trainees in Hermosillo, Mexico. The impromptu practical demonstration took place when a nearby OSM recloser operated to lockout on a 3kA earth fault.
The OSM recloser was minutes away from where service director Oleg Samarski was conducting a training session on the OSM Recloser to the installation and service crew. The training covered basic recloser configuration theory and applications and advanced data analysis using TELUS - the OSM Recloser's built-in data analysis software.
Oleg demonstrated the OSM's data-logging and reporting functionalities in a real-world setting. Connection was made to the device using TELUS software and the data was downloaded and analysed. The software translated the data into relevant, useful information and diagnosed the cause of the fault. Trainees were able to view the practical applications of their training on the recloser device that was operating in +42°C conditions.
