Creative Micro Systems offers Distribution Transformer Monitoring For Smart Grid Communication Solutions in Bangalore. Distribution Transformer Monitoring is a reliable solution which offers the monitoring, the centralized diagnosis of the alarms and the immediate dispatch of the electrical, non-electrical parameters is very important in order to improve network efficiency and reliability then reduce the frequency and duration of failures which helps to improve restoration time and also reduce operational costs. Smart Grid is a form of electrical grid which includes a variety of operational and energy measures such as smart meters, smart appliances, renewable energy resources. Distribution Transformer Monitoring is the process of gaining and processing of data which is related to various parameters of transformers so as to predict and prevent the failure of a transformer.

Distribution Transformer Monitoring For Smart Grid Communication Solutions

Smart grid is a term used to describe the transmission and distribution (T&D) infrastructure of electrical power in a region. Smart grid solutions can help optimize energy efficiency, reduce carbon emissions, and improve reliability and security. The main components of a smart grid are sensors that collect data about the power system and communication networks that enable real-time information sharing. Sensors in smart grid systems include voltage, current, and power flow analyzers. They transmit their data over a network to a central control unit. Transformer monitoring is a key component of smart grid monitoring solutions. It includes monitoring voltages, currents, and power flow across transformers in order to detect abnormalities and predict failures before they happen.

Transformer monitoring systems use different types of monitoring devices: voltage sensors, current sensors, or power flow analyzers that measure voltage or current levels across the transformer’s primary winding(s). Voltage sensors monitor voltages within the transformer’s primary winding and provide an alarm if there is a short-circuit or open circuit. Current sensors measure currents through the transformer’s primary winding and alert operators if there is an open circuit or excessive leakage current through the winding. Power flow analyzers measure voltage across the entire transformer’s primary winding at any time during normal operation.
