Because knowledge is power, the monitoring of high voltage assets such as power transformers has always been of the utmost importance for the electric utility industry. Ontime accurate data on the condition of a power transformer fleet supplies valuable information on the grid’s health, allowing electric utilities to make informed decisions on a daily basis. Being the bridge between the utility operator and the power transformer data, the main control cabinet saw its volume getting bigger over the years to house an increasing number of electronic devices. Electronic temperature monitors, electronic annunciator panels, global monitoring devices, tap changer controller and monitoring units, paralleling controller, dissolved multi-gas analyzers and bushing monitors have all made their way on power transformers and into the main control cabinet.
Nowadays, as the power industry faces the big data era, power transformer manufacturers are required to select, integrate, install and configure these devices, gather all their data efficiently, and most importantly make sure the data will securely transfer to the final customer SCADA system using their specific communication protocol once the transformer is energized. Considering the number of possible devices, the various brands and models for each device type and the electric utility-specific SCADA requirements and communication protocol, the task can be daunting. As a specialized power transformer control cabinet designer and manufacturer, Nomos’ recognized expertise can be requested. We can conduct for our business partners an Integrated Factory Acceptance Test (IFAT) at the power transformer factory on any of our control cabinets.Brochure - IFAT
