Monitoring System
Transformer monitoring system is efficient tool to monitor and diagnose status and condition of transformer and its equipment. NSET solution gives the customer scalable opitons to monitor and diagnose different parameters of transformer. The system is equipped with scalable options for integrating sensors and meassuring equipment to common procesing platform. All the data are processed on the transformer unit, equipped with efficient processing unit suitable for outdoor installation. Processing unit is equipped with different communication options. It has capability for agregating and buffering the data and it has a web server option that gives online visualization option for remote connecting over internet . In the control centre server PC platform ensures appropriate database storage for lifetime data of the transformer.
• Efficient power transformer monitoring system
• Customer‘s tool helps to diagnose problems and maintain equipment
• State–of–the–art technology
